14.8V 2600mAh 18650 Li-ion Battery Pack 4S1P Rechargeable Lithium Battery
$11.00
Rechargeable 14.8V 2600mAh 18650 lithium-ion battery pack (4S1P configuration, 38.48Wh) with dual output — a JST connector lead on one end and a nickel tab terminal on the other. Suited for robotic vacuums, portable instruments, and equipment requiring a compact 14.8V power source.
This 14.8V 2600mAh lithium-ion battery pack is built with 18650 cylindrical cells in a 4S1P configuration, delivering a typical capacity of 2600mAh (minimum 2550mAh under 0.2C standard charge/discharge) and 38.48Wh total energy. The pack features a dual-output design: a JST-style connector with red/black lead wires on one end, and a nickel tab terminal (for spot-welded or bolted connections) on the opposite end.
The pack supports standard charging at 0.2C (520mA) with CV cutoff at 16.8V, or fast charging at 0.5C (1300mA), completing a full charge in ≤5.5 hours standard or ≤2.5 hours fast charge. Standard discharge current is 0.2C (520mA), with a continuous maximum discharge of 0.5C (1300mA, momentary 2C peak), a discharge cut-off voltage of 11V, and discharge over-current protection triggering between 8-16A.
Operating temperature range is 0~45°C for charging and -10~60°C for discharging, with internal resistance ≤320mΩ (AC 1kHz). The complete pack weighs 205±5g.
