ECO-WORTHY 12V 10Ah Lithium LiFePO4 Deep Cycle Battery with 3000+ Cycles, Built-in BMS, Perfect for Fishfinder, Lighting, Power Wheels, Lawn Mower, Cyberpower UPS, Back Up Power

I bought 2 and tested them.* Over-discharge works, but a bit lower than I would prefer. It cut the voltage around 8.7V, when it should trigger at 10V.* Over-charge works, when charging at 3A and 14.6V (in CC then CV mode), the current would abruptly drop to zero near 14.6V and then after a while spike back up to 3A and then drop to zero, for a number of cycles. I've seen this behavior before as it usually indicates that cell-imbalance triggered a disconnect of the charging circuit (probably due to an over-voltage fault on a cell). After the BMS works to drain the highest voltage cell, it reconnects the battery for charging, which then faults again, and repeats. After leaving the battery connected to 14.6V for a long period of time, this ping-pong effect eventually stopped, which implies that the BMS was able to eventually re-balance all the cells. This is speculation as there is no serial port to directly ask the battery what it is truly doing. Note that when overcharge protection kicks in, the battery is still available for discharging.* When charging at 3A, the thermal camera showed very minimal heat production in the battery. This implies decent battery efficiency, as the production of heat implies energy lost, rather than being chemically stored (which we want more of).In terms of capacity testing, I fully charged each battery to 14.6V, and then drained it at a constant 1A:* Battery 1 had 10.06Ah of charge capacity and 125Wh of energy capacity.* Battery 2 had 10.07Ah of charge capacity and 124Wh of energy capacity.Relative to each other, these are well-balanced, so I'm comfortable using them in series.The batteries weigh 1004g and 1002g.I did not test overcurrent or short-circuit protection. I always use an inline fuse in my applications.

tired of replacing sealed lead acid batteries in your UPS, then this is the way to go. Just make sure you get the proper size.

Nice compact battery i use this battery on solar panel to open and shut my chicken door good buy

Working well for powering my Icom 705

Use in a portable case for Ham Radio POTA rig. I have two of the 10ah and one 20ah to run radios. runs for about 5 hours on 50 watts. Drops to around 4 for 100 watts. NO issue and charges back up quickly.

Purchased 2 of these for my Medical Scooter. It charges with fine with original 24 battery charger.It is very light. With SLA batteries, when the battery runs out of its capacity, I let the battery cool down a bit, and I was able to drive the scooter at a very LOW speed back home. As of any new batteries based on Lithium variant, the charge drops off dramatically toward the end of its capacity. So, I have to make sure the charge on battery is nearly full before I used it. I had to push my scooter back home a couple of times unfortunately. Otherwise, it seems to be working fine. Will have to see how long it lasts.

I bought my daughter a nice ride-on that was not cheap. It came with a double sized lead-acid battery and the voltage indicator (as they all do). After about 3 months, even the double sized battery didn't last 30 minutes before the ride-on would slowly start to die. You know. You've seen it happen.So...I looked up a lithium-ion battery and most were over $100. This one happened to be under $70, so I purchased it.I received it in a timely manner, it was half the size/weight of the lead-acid and was very easy to plug in (had to crimp the wires just slightly for tight fit.I also bought a battery meter for lithium ion as the voltage indicator won't accurately show discharge. https://www.amazon.com/gp/product/B08K341JBP/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1. they are cheap, comes with a pack of two. The only lesson I learned is that once you plug in the wire to the meter, it does not come out without destroying the wire. I digress.I took my daughter out for a ride on the charge it had. We went for about 45 minutes (prior to the battery meter install). It didn't miss a beat.I fully charged it this past weekend and then I got the full understanding of what this little battery can do.1. Daughter drove 10-15 minutes to another house, some uphill.2. Had friends driving around constantly for 30-45 minutes.3. Drove back home another 10-15 minutes.On arrival at home, the battery meter still showed 35%. So...a full hour(ish) and still had enough for maybe another 25-30 minutes? I'm sold!BTW, there were always 2 children in the vehicle when arrival at the alternate house. extra payload did not overstress the battery!Worth every penny.
