6600 mAh 3.7 V lithium-ion pack
This battery pack combines three 18650 cells into a single 6600 mAh module with an integrated protection circuit. It is suited for hobbyists and engineers building custom 3.7 V power sources for bike lights, RC models, robots or portable electronics.
Sustained 7 A discharge with polyswitch limit
Under continuous load the pack delivers up to 7 A, capped by the on-board polyswitch that also guards against reverse polarity. The PCB prevents over-charge above 4.2 V, over-discharge at 8.0 A and short circuits, maintaining stable output during extended runs.
69 × 54 × 18 mm form factor
The wrapped assembly measures 69 mm long, 54 mm wide and 18 mm thick with 18-gauge wire leads, determining whether it fits inside the target enclosure. No other dimensions or mounting features are provided.

Questions about this item
Does the 7 A polyswitch limit heat when the pack runs all day at high load?
The 7 A polyswitch caps discharge current at 7 A, limiting heat build-up during sustained high-drain use.
What connector or charger do I need to charge the 3.7 V 6600 mAh pack?
The pack ships with 18 AWG wire leads; you need a 3.7 V Li-ion charger that terminates at 4.2 V and does not exceed 6.5 A charge current.
Will the 69 mm × 54 mm × 18 mm pack fit the battery bay of my older 18650 device?
The module measures 69 mm long, 54 mm wide and 18 mm thick; compare those dimensions with your device's bay before installing.
