2 Pack 12V 15Ah LiFePO4 Deep Cycle Battery, 2000+ Cycles Rechargeable Battery for Lighting, Power Wheels, Fish Finder and More with Built-in 16A BMS

I replaced the singe 7ah battery that was in my daughter's jeep power wheel with both of these. She has used it for multiple days in a row without needing a charge. They are really good for the price. I haven't tried the really expensive ones, but these work great. They are compatible. Easy to install. Right size. And easy replacement.

I bought two sets of these batteries to replace the batteries in my go go scooter. They went right into my small battery box and had to move the wires a little bit to get them to work. I used a lithium ion charger to charge them and they work great. Very strong. I have had no issues but I have only had them for a few weeks. You have to purchase a lithium ion charger for these to work. I bought bigger ones for my big battery box and they work great also.

Bought for dune buggy, thy seem to be working great and lasting

I ordered a pair of these for my mobility scooter to replace the tired lead acid batteries. They worked great and would last all day shopping and going to the park. Then in September, one of the batteries just died. No warning; my scooter's battery gauge showed full charge, then nothing in a split second! Like flipping a switch to off. Immediate death. I removed them from the scooter and charged them individually; one was fine and still working, but the other shows 6.6 volts and refuses to charge. I suspect one or more cells died inside. I ended up having to push the scooter, which is difficult for a person who is disabled. Not sure I'd buy this brand again.

Ordered on the 9th, delivered on the 11th, installed and charged evening of 11th. On the 12th, 6 miles on the mobility scooter. The original batteries were lead-acid, 12 ah. They had been replaced with lead-acid, 15 ah. 5.5 miles max, and only lasted 4 months. (Manufacture said 9 miles with 12 ah) Now, after 6 miles, the battery level indicator has not started to go down. I don't know what the range is with these batteries yet. I know it's in excess of 6 miles. I'll have to update this when I find out. A little concerned about ithium battery fires, but I'm not going to replace batteries every 4 months.
