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

Great replacement for mobility scooter batteries. Much lighter weight and the charge lasts significantly longer than the original lead acid batteries. Be sure to order a new LiFePO4 compatible charger if replacing sealed lead acid batteries.

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 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 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.

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 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.

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

Brought my 3 min backup time to 34 minutes. Definitely worth it. Went right in to my ups with no modifications.

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
