Product Description

Unleash the full potential of your electric bike with our 72V 20Ah Triangle Battery. Engineered specifically for the UK market, this pack is designed for high-performance builds, including Stealth Bomber clones, Enduro frames, and 3600W+ hub motors.


🚀 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 50A BMS

Equipped with a robust 50A Continuous (150A Peak) BMS, this battery can safely support motors from 500W up to 3600W. It offers full protection against over-charge, over-discharge, short-circuit, and thermal runaway.
