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.

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.

Working well for powering my Icom 705

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.

So far, seems to be what I need. Time will tell how it holds up for the long haul. This LiFePO4 battery is a replacement for lead gel cell battery which is much heavier and seemed to weaken in ability to meet brief, high current demands sooner than I expected.

I ordered 2 of these last March and 15 months later one of the 2 has died and won't take the charge. I have used these in parallel to run my kids 12v DynaCraft and it was fantastic. My son would be able to use it for all day long and when we forgot to plug it back in, it was still ready to go the next day. I am saddened to have only 1 battery now, from what I see the 12v 10ah isn't what is sold now, so I need to understand if I can run the existing and a 12.8v 10ah in parallel.

I was initially excited about the arrival of two 10 Amp hour Lithium iron phosphate (LiFePO4) batteries to replace the SLA (sealed lead acid) batteries in my 24 volt battery lawn mower. They're far lighter and slightly smaller than the SLA batteries they replaced. They had nearly 15 volts right out of the box. However, after installing them in the mower's battery case and charging them up for several hours, they didn't even go as long as the SLA counterparts before abruptly failing. The SLA battery generally depletes gradually, but the LiFePO4 pack just suddenly quit. One of the batteries of the two-pack went to just under 10 volts while the other was around 14 volts.Thinking it was just a defective battery, I had Amazon replace it, which they did immediately and without problem (kudos to Amazon's customer service). I put the replacement in with the other and charged them up again, then went to mow the lawn. Same thing happened as the second of the original two LiFePO4 batteries failed.This time, I got a refund on the failed battery which, again, Amazon did immediately and without question.Currently, I'm using the remaining LiFePO4 battery coupled with a used SLA battery which, after appropriate charging time, came up to 27.5 volts and lasted about half the duration of the total SLA battery pack.I'm generally a fan of LiFePO4 batteries, but this company seems to have quality control issues and I will not be getting any more of this brand.

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