Good battery
This is really affordable compared to the performance that it offers. I tested it to output 100 continuously for 30 mins. Works fine no problem. The capacity is accurate enough. Good battery

Huge Upgrade Over My Old 12V Batteries
These 12V 8Ah lithium batteries have been a real upgrade compared to the old lead‑acid ones used before. Perfect size and The first thing noticed was how light they are, which makes them much easier to move around and install in tight spots. They hold a charge really well; even after several uses, the voltage stays strong and consistent instead of slowly sagging like the older batteries did. Charging time is noticeably faster too, so there is less waiting around between uses. So far there have been no issues with overheating or weird behavior, and the terminals feel solid when tightening everything down. For the price of a two‑pack, this feels like a smart long‑term investment for any 12V setup that needs reliable power.

Nice 12v batteries and great for solar applications!
I use these batteries to power solar lights along with a solar panel. They hold a charge well and have plenty of juice so that I won't have to worry about changing them out for a while.

Perfect razor scooter replacement!!
Perfect for my son's Razor mini chopper! This battery is easily half the weight of the lead acid batteries his razor chopper had in it and these are higher Amp-Hour packs. Higher capacity (More run time) + less weight= BIG WIN!!!
