Reviewed & Wrote by Panbo You may not have heard of WattCycle before, but if you are in the market for a value oriented lithium iron phosphate battery, you should probably take note. WattCycle offers numerous batteries in multiple voltages at attractive price points. We have certainly seen batteries with low price tags and performance to match. So, the question is, how will WattCycle’s batteries perform? I have tested a pair of batteries extensively and have some pretty positive results to share. I tested a pair of WattCycle’s 12 volt nominal, 100 amp-hour lithium iron phosphate (LiFePO4 or LFP) batteries with low temperature cutoff and Bluetooth communications. The batteries roughly fit BCI’s Group 24 size and currently sell for $219.00. WattCycle offers a possibly excessive number of 100 amp-hour, 12 volt batteries. Five to be exact. They offer a mini battery with and without Bluetooth communications (both are $189), a group 24 with and without communications, and a “pro” battery without communications and a lower rated BMS than the Bluetooth group 24. I can’t see why you would buy a battery without Bluetooth communications when one is offered at the same price with them. WattCycle’s 12 volt batteries are available in sizes up to 300 amp hours or 3,840 watt hours. They also offer a 24 volt, 100 amp-hour battery that delivers 2,560 watt hours. For higher voltage configurations, they offer bundles of two, three, and four batteries. The 12 volt batteries support up to 4 parallel and 4 series installations. The 24 volt batteries also support 4 parallel but limit series length to 2 batteries. Battery construction The case of the 100 amp-hour, group 24 battery I am evaluating is glued together. As a result, dissassembly requires some creative prying and pounding. Fortunately, the case wasn’t too hard to get apart and I was in pretty quickly. The 100 amp hour mini battery’s case is screwed together which makes disassembly a lot easier.    The battery opened reveals the BMS and cells held in place by a nicely made frame Once inside the battery I found a no frills but nicely constructed battery. The BMS sits well secured atop the cells. It is nice to see no foam in the case with everything instead secured via a well fit cell holder system. I wasn’t able to find a size marking on the positive conductor, but I think it is likely a 4 AWG wire. The negative leads both to the BMS and from the BMS to the negative stud are dual 8 AWG wires. Once I removed the cell pack from the case, I found the cells are actually on their side. A relatively stiff and robust metal frame holds the cells in place. There are two temperature sensors on the cells. Spot welds secure the bus bars to the cell terminals as well as the positive and negative connections from each end of the pack. Lastly, the balance and temperature sensor wiring is protected in a spiral loom. Interestingly, the QR codes for these cells don’t decode using any of the decoders I usually use. I am not sure if Watt Cycle is getting their cells from a new manufacturer or if the QR codes have been modified or faked in some way. I don’t really suspect that to be the case based on everything I’m seeing, but anything is possible. As soon as I removed the heat sink from the BMS, I knew I wasn’t going to learn too much about it. Black epoxy coats the entire circuit board. That certainly cuts down on any conclusions about the BMS beyond the 12 FETs visible at the bottom of the board. I assume these FETs are divided into charge and discharge banks meaning there are six for each purpose. Physically, this BMS is a good bit smaller than most I’ve reviewed recently. But, the proof will be in the pudding of how the battery performs and we will get to that next. The manual includes detailed specs, installation instructions, and more No review of a battery is complete without taking a look at the manual itself. WattCycle’s manual is better than most value oriented brands. The manual includes good detail on the operating parameters of the battery, installation instructions, wiring diagrams, and more. Unfortunately, there is some detail specified in ABYC’s E-13 Lithium standard lacking from the manual. That lack of detail, including items like physical restraint, would make it difficult to complete a compliant install with these batteries. Battery Performance First up, a capacity test of the battery confirms it delivers in excess of its 100 amp-hour rated capacity. In this case, it was just a little bit over at about 101.75 amp hours. That is slightly under the 2-3 percent margin over rated capacity I typically see, but still exceeds the manufacturer’s claim. That’s a luxury to which we are becoming accustomed. If you watch the video section above on high throughput testing, you will hear I had some skepticism about the battery’s ability to sustain their 120 amp rating. The reality was, the battery greatly outperformed that rating and only shut down at almost 200 amps of energy coming out of it. For a 100 amp-hour battery, that is crazy. At that rate, the battery will deplete its energy in half an hour. Overall, the battery met or exceeded WattCycle’s ratings and performed far better than I expected for a $219 battery. BMS BMS 120A Max. Continuous Output Power 1536W Max. Continuous Charge Current 120A Max. Continuous Discharge Current 120A Max. Discharge Current 220A (≤6s) Peak Discharge Current 400A (≤0.3s) Primary Current Protection 220A Secondary Current Protection 400A It might sound irrelevant that a 100 amp hour battery can deliver huge current without shutting down. But, take a look at the data table above. The BMS handles surge currents of 220 amps for up to six seconds and 400 amps for 0.3 seconds. Those huge peak current ratings help with inrush current from large motor loads including windlasses, thrusters, and possibly even engine starting (although WattCycle’s manual says the batteries are not to be used for starting). The ratings are impressive for a single battery, but I would expect that generally, boaters will build banks of 2-4 batteries in parallel. As a result, the current handling numbers are multiplied by the total number of batteries in parallel. The APP The app used for the batteries, named BMS Meta, isn’t WattCycle branded. Presumably the BMS manufacturer also publishes the app. The app provides good monitoring of the battery’s status and clearly shows any issues the batteries may be experiencing. The only oddity I observed, and I don’t know if it is an app issue or a BMS issue, involved cell balancing. Any time the BMS initiated balancing, the words “Balance open” appeared under the third cell. The second screenshot above shows this issue. The third cell always shows balancing, even if it is not the highest voltage cell. I suspect balancing is working as it should and there’s a bug in the way it is displayed. Watt Cycle publishes a surprisingly thorough and readable manual for the Bluetooth app. The manual includes good diagrams showing the meaning of various information presented in the app. Often I question the value of the data in the app if the user doesn’t understand what’s presented. The manual certainly helps increase the usefulness of the information. Charging the Battery  An illustration of the charging limitations WattCycle uses Like quite a few other recent batteries, WattCycle manages charging the battery by disconnecting the charge MOSFETs when the battery is full. These disconnects protect the cells from overcharging. LiFePO4 cells can be damaged by prolonged high voltage,low amperage charging. Since LiFePO4 battery manufacturers offer long warranties, they want a way to protect themselves from having to warranty failed batteries attributable to mistreatment. The solution they’ve found is to disconnect the charge MOSFETs. Charge sources expect the battery they are supplying energy to stay connected. If the charge is coming from an inverter, the sudden disconnection of the batteries will lead to voltage spikes. If the charge source is an alternator, the sudden disconnect will also lead to a voltage spike, but the alternator is also vulnerable to significant damage. When we design DC power systems on boats, we make some basic assumptions. One of those assumptions is that batteries will stay connected. With LiFePO4 batteries we understand that the batteries may disconnect in the event of a significant safety issue like a short circuit, over current situation, or over temperature. However, in my mind, a battery disconnect occurring when the battery and surrounding DC system are operating normally is undesirable. You are likely to read a rant similar to this in every review I do of batteries with this functionality. Fortunately, the workaround isn’t terrible. In order to avoid this behavior, we can reduce the absorption voltage. For the WattCycle battery, I was able to set absorption to both 13.9 and 14 volts without any undesirable disconnects. Although this reduced voltage might slightly increase charge time, I don’t expect that increase will be significant. Additionally, as I determined in another test, the total energy capacity of the battery is likely to remain unchanged with a small decrease in absorption voltage. Final thoughts $219 for a 100 amp-hour battery with Bluetooth, good construction and capable of deliver double its capacity is a serious bargain. I wish the charge disconnect behavior was different, but I may just have to make my peace with that. With available capacities up to 300 amp-hours at 12 volts, a large house bank can be constructed. I am confident these batteries can be used to build a reliable house bank at a serious value. It will be interesting to see what batteries they offer in the future and if feedback from reviewers like me, and potentially customers like you, can change the tide on full charge disconnects.

When it comes to building an efficient energy system, choosing the right battery is one of the most critical decisions. Whether you're powering an RV, supporting a solar setup, or running industrial equipment, the right battery can ensure reliability and longevity while meeting your specific power needs. Two popular choices in the market are the 12V 100Ah LiFePO4 battery and the 24V 100Ah LiFePO4 battery—but how do we choose? As a trusted manufacturer of high-quality LiFePO4 lithium batteries, WattCycle is here to help you navigate the differences between the 12V 100Ah and 24V 100Ah battery options. Which one is better for your needs? Understanding the Basics of 12V and 24V Batteries Voltage is the force that drives electrical current through a circuit, and it plays a crucial role in how power systems function. The 12V and 24V designations indicate the battery's voltage level: 12V Batteries: Provide lower voltage, making them suitable for smaller systems that don’t require significant power. 24V Batteries: Deliver higher voltage, reducing the current demand and improving system efficiency, particularly for larger or high-demand setups. The choice of voltage has a direct impact on wiring complexity, energy loss, and compatibility with devices and inverters. Capacity and Energy Storage The Amp-hour (Ah) rating indicates how much current a battery can supply over a specific period. While both 12V 100Ah and 24V 100Ah batteries in this comparison have a 100Ah rating, their total energy output differs because of their voltage. Energy Output Formula:   Energy (Wh)=Voltage (V)×Capacity (Ah)   12V 100Ah Battery: Stores 1,200 watt-hours (Wh) of energy. 24V 100Ah Battery: Stores 2,400 watt-hours (Wh) of energy. This means that while both batteries have the same capacity in Ah, the 24V 100Ah LiFePO4 battery provides double the energy output, making it more efficient for high-power applications. Comparing 12V 100Ah and 24V 100Ah Batteries Feature 12V 100Ah Battery 24V 100Ah Battery Energy Output (Wh) 1,200 Wh 2,400 Wh Current Demand Higher current flow, thicker wires Lower current flow, thinner wires Portability Lightweight and compact Slightly larger but space-saving Applications RVs, boats, small solar setups Industrial, off-grid, EVs Efficiency Moderate High efficiency for long distances   Key Features of 12V Batteries Compact and Portable The 12V 100Ah lithium battery is known for its smaller size and weight, making it easier to handle, install, and transport. This portability is especially valuable for mobile applications such as RVs and boats, where space is often at a premium. Energy Storage Capacity With an energy output of 1,200 watt-hours (Wh), the 12V LiFePO4 battery is ideal for systems with moderate energy demands. This capacity is sufficient for running basic appliances such as LED lights, small fans, and low-power electronics. Compatibility with Standard Systems Most common inverters, solar charge controllers, and electrical devices are designed to work seamlessly with 12V systems, making these batteries highly versatile. Applications such as backup power for small devices or powering trolling motors rely on the 12V 100Ah LiFePO4 battery for its compatibility and ease of use. Ideal Applications for 12V Batteries RVs and Campers: Provides power for lights, fans, and small kitchen appliances, ensuring a comfortable experience on the road. Marine Use: Commonly used for trolling motors, fish finders, and onboard electronics in boats. Backup Power Systems: Powers essential devices like routers, medical equipment, and emergency lighting during outages. Small Solar Setups: Perfect for small-scale solar projects where energy demands are moderate.   Key Features of 24V Batteries Higher Energy Density The 24V 100Ah LiFePO4 battery stores 2,400 watt-hours (Wh) of energy—double that of a 12V battery with the same Ah rating. This makes it a superior choice for systems that require higher energy output or need to run continuously for extended periods. Reduced Current Flow Higher voltage means less current is required to deliver the same amount of power. This reduces: Energy Loss: Lower current flow minimizes energy wasted as heat. Cable Size: Smaller, more cost-effective cables can be used in 24V systems compared to the thicker cables needed for 12V setups. Simplified Wiring and Setup Unlike 12V systems that may require multiple batteries connected in parallel to achieve the desired capacity, a single 24V battery simplifies installation. This reduces the number of connections and potential points of failure, making the system more reliable and easier to maintain. Ideal Applications for 24V Batteries Industrial Equipment: Powers heavy-duty tools, forklifts, and other machinery requiring substantial energy. Off-Grid Solar Systems: Ideal for large-scale setups that demand efficient energy storage and delivery. Electric Vehicles (EVs): Provides the higher voltage necessary for powerful motors and longer operating ranges. High-Demand Applications: Supports telecom towers, data centers, and other systems requiring uninterrupted, high-capacity power.   Why Voltage Matters The difference in voltage between 12V and 24V systems affects not just the performance but also the cost and complexity of your setup. Efficiency in Transmission A 24V battery delivers the same power with less current, resulting in reduced resistance and heat generation. This is especially beneficial for systems with longer cable runs, such as off-grid solar setups or industrial sites. 12V batteries, while adequate for small systems, can experience higher energy losses over long distances due to the increased current flow. System Design 12V systems are simpler and more accessible, making them suitable for beginners or small-scale setups. 24V systems often require specialized components like inverters and charge controllers, but these can pay off in terms of long-term performance and reduced maintenance costs. Scalability and Expansion 12V batteries can be connected in parallel to increase capacity or in series to increase voltage (to 24V, for instance). However, parallel configurations can lead to uneven load distribution. A single 24V battery eliminates this issue, offering a cleaner and more efficient design for larger systems. How to Choose the Right Battery Assess Your Energy Needs If you’re looking for a portable and cost-effective option for light to moderate power requirements, 12V batteries are a great choice. For larger setups or high-power applications like industrial equipment or off-grid systems, 24V batteries are better suited.
