Molicel INR18650-M35A

MolicelBattery Cell

High-capacity 18650 cell from Molicel. 3500mAh capacity with 10A continuous discharge. The highest-capacity cell in Molicel's 18650 lineup, offering excellent energy density (264 Wh/kg, 730 Wh/L). Ideal for range-focused builds where moderate discharge is sufficient. A step up from the Samsung 35E in capacity.

In brief: 18650 Li-ion battery cell. 3500mAh capacity. 6A continuous discharge.
