Good battery so far…bad app

Time will tell on the battery itself but the ordering process was smooth and delivered as promised. The app is another story. The available instructions are worthless and there seems to be confusion as to what app to actually use. The app screen is not intuitive and provides info that is confusing.

24 volt wiring kit

Easy to use and works as it should

Battery contector

Parts are well make & work well

So far so good!!

Battery seems good; bluetooth and app, no so much

Not sure how to rate this battery as the bluetooth range seems really small and the "new" app seems to have issues. I can't seem to get an answer from wattcycle on if there's a firmware upgrade on the bluetooth or when the new app will be in better shape. Once I get a response, I'll update my review/rating

vert impressed

I needed longer battery life, my old 100ah battery just wasn’t cutting it. With this battery I can run my fridge/freezer 3 times longer without worrying about running low on battery life.

12v50Ah batteries

Seems to be really good batteries. They are performing well.

Excellent Batteries

I have 2 of these 100ah batteries hooked up in parallel that is use to power my mobile ham radio in my truck. They perform flawlessly. Fantastic price and shipping was fast. Highly recommend.

Weight Savings Revolutionized My Trailer

Saved 200lbs swapping to this lithium beast. Towing efficiency improved, and the 314Ah capacity outlasts my old 400Ah lead-acid. BMS is a safety hero during fast charges.

Bye-Bye, Lead-Acid Bulk!

Switched my off-grid cabin to this—saved 150lbs! The true 314Ah capacity lasts 2 days longer than my old 420Ah lead-acid bank. BMS protection is rock-solid. Zero regrets.

Lithium’s Math Just Makes Sense

Lead-acid needs 600Ah to match this 314Ah? Nonsense! This powers my trolling motor all weekend. Lighter, smaller, longer-lasting—the ROI is undeniable.

Unbeatable Value vs. Lead-Acid

Compared 314Ah lithium to 400Ah lead-acid—this outperforms in actual capacity while taking 60% less space. The BMS ensures stable voltage during high draws. Efficiency is unreal!

Great batteries

Converted the RV over to lithium batteries in May with 2 100ah batteries they fit great and so far they have worked well. Shipping was fast and the batteries arrived in good condition. Would order from watt cycle again.

Lead-Acid’s Death Knell!

Why tolerate lead’s inefficiency? This charges faster, discharges deeper, and lasts 10x longer. The 300A BMS and compact design make it the ultimate upgrade. Just buy it!

300A BMS = Peace of Mind

Runs my 3000W inverter flawlessly. Unlike lead-acid, voltage doesn’t sag at 70% discharge. Efficient, lightweight, and no maintenance. Lithium’s cost-per-cycle destroys lead-acid.

Blue Tooth needs improvement

Good Value overall. However the BlueTooth needs a better range. Installed these batteries in mu RV and cannot use the app inside the RV, not even standing over the batteries that are just below the floor. WattCycle also needs better Charge / Discharge graphs. The ones provided are difficult to read because of the scaling. A chart would also be very helpful, but WattCycle claims not to have any charts even though a chart was needed to plot the graph.

The only way to connect batteries

This harness takes all the guess work out of linking your batteries in a series. Just connect all the wires up and plug the ends in and it’s done. They also come with really nice heat shrink connectors to hook up to your main power wires. 100% a must have for a 36v system.

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.

Silent, Efficient Powerhouse

No fumes, no noise, no weight! Replaced 3 lead-acids in my solar setup. The 300A BMS handles surge loads safely. Efficiency gains cut my generator runtime by half.

Safety & Compact Design Win

No more acid leaks or ventilation worries! This stays cool under heavy loads. The size/weight saved my boat’s balance, and 300A discharge means quick starts. Brilliant engineering.

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!!

Half the Size, Double the Power

Fits where my old 200Ah lead-acid sat but delivers 314Ah real power. Charging is 3x faster, and the BMS prevents overloads. Perfect for tight campervan installs!

Game-Changer for My RV!

Replaced four lead-acid batteries with this single unit. Half the weight, triple the lifespan, and the 300A BMS handles my inverter without breaking a sweat. Worth every penny!

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.
