The ASOL 18650-4S2P is a professional-grade rechargeable battery pack delivering 14.6V nominal voltage and 5000mAh capacity (73.0Wh). Its 4-series, 2-parallel (4S2P) architecture doubles the capacity of standard single-row 4S packs, providing significantly longer operating time for high-drain equipment – fewer battery changes, less downtime, higher productivity.

Each pack is equipped with an integrated BMS protection circuit offering comprehensive safeguards against overcharge, over-discharge, overcurrent, and short circuit. This ensures consistent performance across a wide temperature range (−20°C to +60°C) and under demanding load conditions.

Produced by ASOLENERGY TECHNOLOGY under the ASOL brand, every unit undergoes a strict quality control process: cell voltage matching, full charge/discharge cycle testing, and BMS functionality verification – all before it leaves the production line.
