🚀 Why LG INR21700-M50 Cells Matter?
We use genuine Grade-A LG M50 cells (5000mAh). These 21700 format cells are the industry standard for high energy density. They provide consistent voltage even under heavy load (sag less), meaning you get higher top speeds for longer.
⚡ High Discharge 60A BMS
Equipped with a robust 60A Continuous (150A Peak) BMS, this battery can safely support motors from 1000W up to 4000W. It offers full protection against over-charge, over-discharge, short-circuit, and thermal runaway.
