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.

Used these to replace the battery in my CyberPower 1100 UPS Battery Back-Up. I replaced the 7Ah PB Lead Acid Battery with a 10Ah LifePo4 Battery. Batteries came charged at 12 volts. Tested UPS after installing and everything works great! No issues so far!

Very light battery. Charging was quick.

So far knock on wood, using 4 LiFePo4 in dual CyberPower CP1500PFCLCD (daisey chained) to provide my heavy overload protection for summer time is perfect! Summary: Initially I could not "re-activate" 2 of the 4 batteries due to low battery state fail-safe shutdown, so i ordered replacement but looks like the user manual says to use an Re-activate charger type to wake it back up. Echo Worthy has this Reactivate-charger feature, I didnt know at he the time.

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.

I don't really like the spade terminals, but I just needed a super portable battery to power a 12v fridge. This does the job.

Solid LifeP04 battery for a great price. Sadly, it does not work in the CyberPower 1000AVR UPS that I intended to use it for, despite what the seller claims in the listing. The onboard BMS cuts out on powerup, and the UPS loops into a continual reboot cycle. I believe that the initial start-up battery test exceeds the 10A draw limit for the battery and the BMS cuts output. Otherwise, great battery for the price for other applications. I ended up putting this battery in my alarm system which now has days of backup power and a battery that won't have to be changed again for at least 10 years.

Charger début de l’été et installer dans 4 roues électrique pour enfant sans recharge fin septembre mes petits enfants sont venus et utiliser le 4 roues pendant plus de deux heures intensifs sur mon terrain en terre et légère pente et la batterie n’a jamais lâché, très bonne batterie
