I bought this battery four weeks ago, and wanted to use it for a while before writing a review. I use the battery to power amateur radio equipment while camping in the mountains and charge it with solar using a Victron MPPT solar controller. The battery actually has slightly over 100ah capacity, and works exactly as advertised. The iPhone app is annoying, as every time you open the app you have to reconnect to the battery, and it's also annoying that I have to create an account with the company to manage a battery I already own. On the plus side, the amp/volt/watt readings in the app agree almost perfectly with my own measurements across a 1-ohm shunt and the estimated time remaining to depletion and/or charge display saves me from having to do a bunch of mental math. App issues aside, it gets 5 stars as the battery itself it excellent. I'll almost certainly buy two more to replace the pair of failing lead-acid batteries in my camp trailer.

This is working great for my trolling motor. I made the mistake of derating it in the BMS and went overboard. You can charge this battery to 100% and still get 4,000 cycles. It has a lot of power. I run a 12 volt Haswing trolling motor all day with this and have plenty of power to do a second day, if I wanted. The motor can use up to 800 watts, but typical draw is about 120 when I am trolling for Kokanee. The battery is lightweight for its size, and is amazing. I highly recommend this!! Great seller who communicates and answers questions.

I bought this as a trial battery for my overlanding setup. This thing is amazing and the app is great!! Definitely worth it! I told our shop guy for overlanding to buy these!!

Only had about 4 days. The battery came at 50% charge. Filled it up and mounted in my trailer. So far it works great. App says the capacity is 101ah which is about what my charger says.The only complaint is the app/Bluetooth. It doesn't stay connected very well. And when it disconnects, it takes awhile to reconnect. But overall, the battery works as planned.....so far.

I have not had a chance to use these batteries during a blackout yet. They charged up fast. it is recommended to charge the batteries when delivered. Thy are less the half the weight of a glass mat battery.

This is my 2nd 100 ah battery. The price was so right that I bought another as a spare. Good thing too because my big name brand just shut down for the 2nd time in a month. Last time I was without for 2 weeks. The original 100 ah is dedicated to electronics in my boat and it’s been rocking along mirroring the performance of my name brands that run my trolling motor. The app is reliable and full off all the information I need as well. I’ve also purchased and installed 3 more in my neighbor’s boat. Another friend did the same in his boat and had an issue with the BMS reading the wrong temperature but that issue was resolved quickly by tech support and it was actually resolved via the app remotely. Nice!

I bought 4 of these to convert my Ryobi 48" Zeroturn mower from lead acid to lithium. The lead acid batteries in that mower are notorious for dying after a year or two. The cost of LiFePO4 batteries has come WAY down and are now in line with the cost of lead acid for equivalent energy capacity.Oddly, buying 4 of these batteries to create a 48V, 100aH pack is less expensive than buying an integrated 48V 100aH battery. That doesn't make sense to me. Anyway, these batteries are slightly larger than the lead acid they are replacing, but about 1/3 the weight. They still fit in the mower battery tray, but just barely.I bought a new charger to use with them as the Ryobi charger for lead acid does not charge to the right voltage for LiFePO4. I didn't bother changing the power gauge on the mower, so it doesn't read the capacity accurately due to the voltage difference between SLA and LiFePO4. That is where the bluetooth BMS on these batteries comes in. I can get info about their state of charge through my phone. It can also give me a chart of the current usage as well.The phone app to connect to the batteries is not very full featured and has a few translation problems, but it works for what I need it to. You have to cycle through each battery one by one and it can be a little slow to connect. Aside from the initial playing with it, however, that isn't really important. Just reading one battery gives a good indication of the charge left in all of them as they stay pretty balanced in series.I've been using these for about 3 months this summer and they are fantastic- they run the mower far longer than the lead acid batteries they are replacing. Hopefully they have a long lifetime and don't degrade quickly over time.5 stars for now. I'll come back and update this review should anything fail prematurely.

I've had it for a few months now so I thought I could provide a review based on actual use. So far so good. Have dry camped multiple times with it and it's performed well. I'm happy with the capacity and while the BMS app isn't ideal, it does work.Seasonal update: after a full season of camping and using solar to charge it has worked out well. I will update if anything changes. Otherwise thumbs up here.

It’s so light, hard to get over it.Just got it today, reads 109 amps so great start.Used overkill solar app.Changed the cold temp to 0c from -10c. Using the above app.Spec sheet says 4000 charges until 80%So, for me well over 10 years.I use it for my sump pump backup but obviously, extremely portable unlike its lead acid predecessor.Now I have double the power for a quarter of the weight!!!
