      Working Like It Should

      When I first used the charger I was not sure if it was working correctly. It cycle on and off a number of times. I eventually heard from support and they assured me it was working correctly. On subsequent chargings it only cycle on and off once, suggesting maybe it was doing initial battery conditioning?

      Now that I have used it a few times, I am happy to say that it charges well and gets my battery up to full charge. I have measured its charging rate and it is in the 19-20 amp range when first charging and then lowers as the battery reaches full charge.

      I plan to use it when the batteries are removed from my RV in the off-season.

      Worked well.

      I purchased this charger to fully charge my 3 new 12v 100ah batteries before hooking them up in series for my golf cart. Did the job quickly.
      Now I have the 36v charger installed that is also working very well.
      Batteries have performed well for the 2 weeks they have been in the cart. Less weight, a tad bit faster and longer run time.
      Happy so far!!

      Great battery with 200A continuous output capability!
      i replaced 3 old 100Ah AGM batteries that were old and no longer had any depth of charge.
      i ran my circular saw off this through my 2500W inverter. 🤣
      I also load tested a microwave and breakfast sandwich maker (Foreman grille style thing) and was able to run them at the same time. Great for at the race track.

      The app is nice to help keep track of the SOC, but it has some confusing warnings that are not really warnings, just normal functioning, like the Over Voltage warning as it approaches 💯 through solar charging

      Price was great compared to other options too.

      Great value!

      Ordered this battery to replace a 100Ah LiFePo that powers my teardrop camper. I wanted an option that did not add significant weight or size (went into same battery location as the previous battery). The new battery will power my dual zone 12v fridge,assorted lights, and Starlink.
      The WattCycle battery should allow me to spend longer while boondocking.
      Looking forward to testing it out in actual conditions!!

      Does the Job

      Use to charge Wattcycle 280. Charges in reasonable time. Helpful display to match my Victron shunt and Bluetooth from battery. Added inline heavy duty on/off power switch to better control charging cycle.

      amazing batteries

      I purchased 2 -12 volt 100 amp hour batteries connected them together for 24 V. I actually could go four days without heavy wind but in a pretty stiff current in the Missouri river. After four days, the battery still showed 74% I was amazed. The batteries did take quite a few days to get shipped however, it was a great price and well worth the wait.

      Battery works great in my RV. Replaced the 85Ah lead acid battery. Increased capacity by more than 300% but only increased weight by 30%. Cell balance is always within spec. I like being able to see my usage and estimated hours left. Starts my generator without any issues.

      BEST CHARGER IVE EVER OWNED

      This charger is an absolute BEAST!! By far the best 4 bank charger I've ever owned. I've been running it for about 6-8 months and its performed flawlessly!! Guys If you're not familiar with what I do, check out my socials and you'll see me put everything I own to hard work! I am rough on my stuff! I buy it to use it and I don't care about a scratch, ding, or dent. I put my boat and all my equipment through the ringer every time I go out. WattCycle makes QUALITY products at an incredibly low price! https://www.facebook.com/JoelDavisFishing

      Great battery

      The battery is nice. Great for ham radio and keeping everything charged up

      Nice batteries

      That are gonna work good for my 24 volt system. I am just now setting up system, this will have hydro power also.

      I plan to use it when the batteries are removed from my RV in the off-season.

      Absolutely love these batteries. I already had 3 of the 12v 100Ah for my Ranger Z520 and when I bought my Clubcar I knew I was going with the 12v 50Ah. I dropped 320lbs off my golf cart and I used to have to charge the lead acid batteries every day just to get around my neighborhood. So far the first charge on the WattCycle 12v 50Ah has lasted 4 days!!! I am extremely satisfied with my purchase!!!!

      Overbuilt & Over-Delivers

      Running heavy-duty tools at my remote job site. This unit laughs at 150A continuous draws! Case feels military-grade, and Bluetooth alerts saved me from accidental over-discharge twice. Surprised by how cool it stays even at 95% DoD.

      Solved Our Peak Demand Charges

      My solar company installed 8 units for a commercial client. The 100% depth of discharge and 6,000-cycle lifespan crushed competitors. Client’s peak utility charges dropped 65%! Installation was tool-free – slid right into standard racks. Customer service even helped tweak BMS settings remotely. Highly recommend for commercial scale.

      Overkill for Overlanding (in the best way)

      Powers my winch, fridge, and camp setup for a week. Survived desert heat (45°C) - BMS kept temps below 40°C at 120A draw. Bluetooth graphing showed voltage stability during winch spikes. Case took rock impacts without denting. Zero capacity loss in 8 months!

      EV Conversion Game-Changer

      Used two of these for my golf cart → mini-truck conversion. Delivers insane torque at 24V! Bluetooth monitoring shows cell balance within 0.01V even under load. 300Ah gives me 70+ miles per charge. Waterproof casing survived monsoon rains. Lifespan is unreal!

      RV & Golf Combo Perfection

      Dual-use superstar! Powers my EZ-GO TXT for 35+ miles, then runs my RV fridge overnight (5.3kWh is no joke!). Bluetooth alerts saved me from deep discharge during camping. Only gripe: Mounting holes needed slight adjustment for my Yamaha. Still – 10/10 performance in Arizona heat!

      Unbeatable Range for Resort Golf!

      Upgraded my Club Car Precedent with this 105Ah beast – now I get 48 holes on a single charge at our hilly Florida resort! The extra 5Ah over competitors makes a real difference. Bluetooth app shows precise battery health, and the weight reduction improved my suspension. Zero maintenance worth every dollar!

      Silent Hunting Machine

      Dead silent through deer country! This 105Ah monster pushes my lifted cart 45+ miles through mud and hills (knobby tires + 800lb gear). Low-temp cut-off kicked in flawlessly at 14°F. Bluetooth range meter is scarily accurate – never stranded. Survived torrential rain (IP65 works!). Best hunting upgrade ever.

      Silent Powerhouse for Hunting

      Rigged this to my hunting cart – dead silent through deer woods! 40+ mile range even with knobby tires and hills. The low-temp cut-off protected it at 19°F. App shows exact remaining miles – no more getting stranded. Survived muddy trails and creek crossings (IP65 is legit). Worth every cent!

      Runs hot

      Can't beat the price and it's compact but it runs hot. The surface is smooth plastic without vents or fins. Maybe it is fine running hot. I would make sure that as much surface as possible is exposed.

      RV Game-Changer

      Replaced 4x lead-acid batteries with this single unit. Powers my 45ft RV for 2.5 days (AC included!). Bluetooth alerts warned me before inverter shutdown. 70% lighter than old setup.

      Finally, a Truly Modular Industrial Solution

      As an industrial automation engineer, I’ve tested dozens of rack batteries. Wattcycle stands out for TRUE modularity – hot-swapped 4 modules in <10 mins when we needed extra capacity. The UL1973 certification gave our facility manager peace of mind. 200A continuous discharge handles our CNC machines perfectly. No cooling fans = silent operation!

      Marine Reliability Masterclass

      Installed this on my fishing charter boat for trolling motors and electronics. Salt spray? No corrosion. Deep discharges daily? Still shows 100% health after 300+ cycles. Bluetooth app tracks voltage dips during engine starts. Built like a tank – handles rough seas perfectly.

      RV Power Solved Forever

      This beast powers my 32ft RV for 4+ days without solar input! The Bluetooth monitoring saved me when my fridge spiked - got an instant alert on my phone. Super lightweight compared to 4x 100Ah batteries it replaced. BMS balances perfectly even at 10% discharge.
