12V 10Ah Lithium LiFePO4 Deep Cycle Battery

I bought this for a small backup power setup and it’s been excellent so far. It’s lightweight, charges quickly, and holds power better than I expected for the size. I’ve used it for lights and a few small electronics, and it’s been steady and reliable every time. The built-in BMS is a nice bonus and gives some peace of mind. For a compact battery, it punches above its weight.

I needed a replacement battery for a 15 yr old rechargeable battery in my backpack sprayer that was an old NiCad battery. Saw a video on YouTube for my identical backpack sprayer, and he loved this replacement battery (lithium). It came fully charged, I installed it and had to do some minor terminal wiring modifications and for a 12 volt battery it came out of the box with about 14 volts. Sprayer was back to life and do my annual Demon WP spray on eves and weep holes for all the spiders and wasps that bug me. Sprayed over 5 gallons and battery was still close to 14 volts.

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.

Eco-worthy might have one of the best support organizations I have seen and worked with. We exchanged communication data and details and we were able to come to a reasonable conclusion of a small problem I was facing and that I'm very satisfied with the result. I got my battery bank back up and running thanks to help from support. Thank you Eco-worthy for working with me and for allowing me to share my feedback. It was my bad for misunderstanding the true use of these batteries and now that I have that knowledge, these little puppies are back in action and helping me with various diy projects I do around the shop.

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.

This is exactly what I ordered and exactly what I needed. Thank you

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.

Revised: I've downgraded this to one Star after it provided only about 5 minutes of backup during a recent blackout. A Gel battery would have lasted half an hour. The idea of replacing a Gel Battery with Lithium is very appealing. Almost every specification of Lithium Batteries is superior to Lead Acid it would appear - except - the charging cycle is different with different voltages and the sustained watts rating seems to be lower than the standard batteries. The BMS enforces the rules and that can be a stumbling block. In other applications Lithium batteries can replace Lead Acid and still work well, although at a reduced capacity if the standard charger is not replaced. Anyway, I decided to try replacing my expired Gel UPS battery with a Lithium Type. I have a Minuteman UPS. I installed the new battery and the Minuteman turned on and seemed to be fine. However, when I moved the UPS to its home, plugged in my many devices then turned it on - the UPS instantly went dead. I had read about folks finding ways around startup problems, I did the following: 1. Unplug all plugs in back. 2. Open case, then momentarily remove, then reattach one of the battery leads. (UPS should beep) 3. Close the case and turn on UPS. 4. Replace the plugs in back one at a time. (This avoids the initial too-high initial draw.) By starting in this way, my UPS is happily doing its job. If I unplug it - it seems to work with power outages. I assume that if I ever have a power outage long enough to discharge the new battery, I will need to repeat the above procedure. I'll know if that event ever comes. I don't know the long-term prospects - or if this procedure will work for you, but if you have issues, give this a try before giving up.

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
