The media could not be loaded. I bought my granddaughter a Mercedes Benz G-Wagon Power Wheels type car for her 2nd birthday, back in September. She didn’t ride it during the winter, the weather cleared so it was time to whip it out and bend a few corners. Nope, it was completely dead, not only that, it would not take a charge, so I was going to just buy her another one but that’s like throwing away your car because it has a flat tire. I did some research and decided to start with replacing the battery, I narrowed it down to 2 and ultimately settled on this one. I was hoping it was the right size and the terminals would be the same. For whatever reason, the toy car manufacturer thought it was a good idea to hot glue the connectors to the terminals (I’m guessing to keep out moisture?) but I got the glue off, removed the dead battery, to my surprise it was a lot heavier than this one, same exact dimensions though. With no modifying the connectors went right on, the battery slipped into the slot—perfect fit and it powered right up! I’m stoked beyond words because it’s not often that you hope you order the right part and it’s an absolute exact fit but also an upgrade. Not sure what anyone else may use it for but it worked perfectly for what my granddaughter’s little car. I’d buy it 100 times over because it shipped next day and brought her little car back to life.

I have used these batteries many times and am very happy with their performance. In my future I will be purchasing more batteries. I have one that I use of of a small 100 watt inverter. I use it to power a lamp in the corner of my bedroom where their is no outlet. I kill the DC current to the inverter by a switch on the wall. So when the lamp is off, you turn the other switch off too. This keeps from wasting power from the inverter sitting by idly. Not doing any work. I use the lamp in a wide and varied manner. It has a 8 watt bulb that is supposed to be the equivalent of 40 watts in lighting bulbs. I get 13 days out of it with intermittent. use.

Arrived , only thing is the box has no labels (this side up) or any sort of way to know what side terminal posts are on. Haven't benched the battery yet. Shipping label is placed on the bottom of box so likely you'll open it upside-down like I did assuming the label was put on the top not the bottom.

The seller doesn't write or understand English. It took over a week attempting to warranty less tan 1 year old dead unchargable12 volt 100ah lifepo4 battery. But seller said they will not replace even though I am willing to wait for new batteries to come in. They refunded me instead. I tried all the online tricks to wake up the battery with but no response. I might take it apart after I get refund but I went ahead ad bought another battery from alliance express. Amazon has no rv size lithium batteries anymore that can be shipped to Alaska.

BMS does not play nice with any of my chargers, and allows the batteries to continue draining as they self recover. Charging with any of my 3 different LiFePO4 chargers, cuts off prematurely, not sure what the BMS cutoff voltage is but it appears to be under 3.6v, gonna try 3.55v next time. Cannot run a discharge test with any of the chargers either, all 3 give the message "Error Balancer detected" So I'm unable to accurately measure battery charging or discharging capacity. But a run test with a DC motor pulling 0.43A tells me that these are about 5500mAh, not 6000, but that may be because of the BMS charging cutoff.... I will probably send these back & find something else.

It's super easy to set up and charge; it charges pretty quick based on your solar setup. It also holds a lot of electricity for how small the battery is. I used it for my solar panels and it lasts DAYS without sun. I would highly recommend this to anyone that is getting into solar panels or off-grid. Great product overall, as it's compact too!
