10.8V 6.7Ah 18650 Li-ion Battery Pack 3S2P Rechargeable Lithium Battery
$15.00
Rechargeable 10.8V 6.7Ah lithium-ion battery pack (3S2P configuration, 72.36Wh) built with 18650 cylindrical cells. Compatible with medical devices, portable instruments, POS terminals, and equipment requiring a stable 10.8V power source with long cycle life.
This 10.8V 6.7Ah lithium-ion battery pack is built in a 3S2P configuration using 18650 cylindrical cells, delivering a typical capacity of 6700mAh (minimum 6500mAh) and 72.36Wh total energy, with an open circuit shipment voltage of ≥10.8V.
The pack supports temperature-adaptive charging: 0.1C (670mA) between 0~15°C, and 0.4C (2680mA) between 16~45°C, protecting cell integrity across a range of ambient conditions. Maximum continuous discharge current is similarly adaptive — 0.2C (1340mA) in cold conditions (-20~0°C) and 0.4C (2680mA) at 0~60°C — with a discharge cut-off voltage of 8.25V and maximum charge voltage of 12.6V.
Rated for 1500 charge/discharge cycles at 0.2C while retaining above 70% of initial capacity, this pack is suited for applications demanding long-term reliability. Internal impedance is ≤220mΩ (AC 1kHz). The pack weighs approximately 302g.
Usage Notes: A minimum 10-minute interval between charge and discharge is recommended. For long-term storage exceeding 3 months, maintain battery voltage within 3.1V~3.45V per cell to preserve cycle life.
