🏆 Powered by LG M50 (21700 Technology)
We use Grade-A LG INR21700-M50 (5000mAh) cells. These are the same class of cells used in Tesla vehicles.
- 960Wh Capacity: Typical range of 35-60 miles (60-100km) depending on throttle use.
- Compact Power: By using high-density 21700 cells, we fit 20Ah into a case that usually only holds 13Ah.
⚡ High Power 50A BMS
Most 48V batteries only have a 25A BMS. Ours is built with a 50A Continuous BMS.
- Best for Bafang BBSHD: The BBSHD pulls 30A. Our battery handles this easily with zero overheating.
- Hill Climbing: Delivers consistent power without voltage sag on steep inclines.
- Compatible Motors: 500W, 750W, 1000W, 2400W up to 3000W Peak.
