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

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.

I bought it for a toy Electric car. Perfect Replacement for lead acid 12V 7Ah

Very light battery. Charging was quick.

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.

Used it one year and worked fine but on second year the battery is bulging so not safe to use. never overcharge or discharged just didn't last more then one year Edit: contacted customer support and sent in supporting photos and they sent me out a new one. Will see but hopefully this one will last longer

At work I scavenged some discarded APC UPS units (BR1000G) from the trash. People throw them out when the batteries die, and the SLA batteries that come with them typically only last a few years. You can buy replacement SLA batteries here on Amazon, the exact ones APC uses without the extra markup. But after doing some research, these Eco-Worthy batteries (2 of them) will fit perfectly in place of the stock SLA batteries. The downside is you really can only get about 200 W (100 W per battery) instead of the full 600 W that the UPS is rated for. If you try to get more, you risk the built-in BMS disconnecting the batteries (the BMS is a safety feature). But the upside is that these batteries should last many years, and unlike SLA, they aren't sensitive to frequent small discharges when the UPS goes onto battery. I hope that the UPS manufacturers move to these types of batteries in the future.

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.

So far, so good.
