The ASOL 21700-4S1P delivers 14.76V nominal voltage and 4800mAh capacity (70.85Wh) through a proven 4-series, 1-parallel (4S1P) 21700 cell architecture. The larger 21700 cell format delivers approximately 35% more energy density compared to standard 18650 cells – translating to longer runtime and fewer battery swaps in the field.
Every pack integrates a multi-layer BMS protection board guarding against overcharge, over-discharge, overcurrent, and short circuit – ensuring safe operation even under heavy load or extreme temperatures.
Backed by ASOLENERGY TECHNOLOGY’s production capability, each unit undergoes full charge/discharge cycle testing, voltage matching, and BMS function verification before shipment. From cell grading to final packing, quality is built into every step.
