Talentcell 12V 12Ah LiFePO4 Battery Pack LF4021, 12.8V 153.6Wh Deep Cycle Rechargeable Lithium Iron Phosphate Batteries

I got 2 of these battery's to replace my dads VIVE mobility scooter. With the vive you have to have the screw down connectors not the clip kind!!!!!!!!!!! VERY IMPORTANT!!!!!!!!!!! Anyway they work very well and alot lighter than the lead battery's I am replacing. Only time will tell how long they last but it should be better than the ones i replaced.

I put this in my child's Peg Perego "Gator" and it works very well, letting him ride around all day. I charge it with a benchtop power supply, with current and voltage limits of 2.5A, 14.5V (about 0.2C). Charging takes about the 5 hours you would expect. The plaque on the battery indicates a maximum charging current of 6.5A, but I have no desire to "push the envelope" and decrease battery life. I have not noticed any leakage of charge when not in use, but it has not been stored for long periods. I've not noticed any degradation in the battery performance over about 30 charging cycles. The label indicates it is rated for 2000+ cycles at 0.2C.Compared to the older lead acid battery I took out of the gator, this battery is extremely light, at maybe a third or quarter of the mass. The casing is strong enough to handle the bumps and jolts of a 4-year old bouncing around a rough yard with no damage. That is important because this battery, at 12V, 12Ah, holds roughly 0.5 megajoule. A stick of dynamite is roughly 1 MJ. Treat it with respect.The terminals on this battery are #12 NF thread female and it came with corresponding machine screws and color-coded ~6" leads.

I’ve had it replaced only to fail twice. Don’t waste your money here with these tricksters.

These batteries look pretty good, and charge up nicely on the recommended charger. 13.4v is my end-of-charge voltage, and it stayed at that for a full mornings use in an RC model boat. Nice that the voltage does not fade away, and so much lighter than lead-acid. I feel happier using them, compared also to Li-Ion, as they are not so dangerous or likely to burst into flames. I leave them in the boat when recharging, which I would not do if Li-Ion. Hopefully the price will continue to drop, but already are competitive. Weight, level voltage, price and safety all add up to an excellent product !

Great little lightweight compact 12 V battery as long as your power leads are sized appropriately. It works amazing.

Bought these for replacements in a 48v electric go cart. Works great! Extremely pleased

The price to quality ratio of this product is right on point

Wish it had different terminal posts. A wing nut or post would be what most wire ends connect to battery. I guess I'll just modify the existing hook-ups in the Ice house. A deep cycle this light hoping it lasts awhile. 🙏
