Li-ion 12V 50Ah Lithium Batteries

A quality BMS with a separate charge and discharge port, plus temperature and balancing!

Tested at 90% or better capacity which means they have very few cycles, will work like new, and have a lot of life left. Eve cells are rated at 1000 cycles!

Using the charge port of the BMS wire you can charge these at 4A。The BMS is top quality and trusted by major brands. It protects against over charge, over discharge, balances cells, and has temperature protection with probes.

These Li-ion batteries are our longest lasting E-Bike Battery, and have a longer lifespan than other types of Lithium batteries. They typically last 2-4 years. They are also our lightest batteries – at half the weight of lead-acid batteries.
