This is a 7.4V 2600mAh Li-ion 18650 battery pack, it’s a compact, high-energy solution built around two premium 3.6V 2600mAh 3C-rated NCM cells in a 2S1P configuration. Delivering 19.24Wh of reliable power, this cylindrical pack (Φ19 × 134 mm) is designed for space-constrained applications such as handheld instruments, medical devices, portable POS systems, and custom OEM equipment.
Each pack integrates a protection board providing over-charge, over-discharge, over-current, and short-circuit protection. Rated for 2A normal working current with a maximum continuous discharge of 4A, it handles moderate load profiles with confidence. The cells are wrapped in a neat blue PVC heat shrink, terminated with 20AWG red/black leads and a pre-fitted MOLEX 2695-03RP connector for plug-and-play installation.
Need more runtime? The same platform is available in a 7.4V 3500mAh (by 18650-3.6V-3500mAh cell) variant in a flat 19.5 × 19.5 × 134 mm form factor, letting you scale capacity without changing your product design. Both variants share the same protection board, connector, and lead color scheme for seamless integration across your product line.
