Product overview

80mah lithium ion polymer for RC Models, Drones, and Smart Devices | Battery Manufacturers in China & Battery Supply Factory

The VTC-LP350840 is a compact Li-ion polymer battery pack designed for rechargeable low-current electronics that require a slim protected power source. The datasheet specifies 3.7V nominal voltage, 80mAh nominal capacity, 85mAh rated capacity, 75mAh minimum capacity, 4.2V limited charge voltage, 3.0V discharge cut-off voltage, 16mA standard charge and discharge current, and 80mA rapid charge or maximum discharge current. The pack dimensions are 3.7mm max. thickness, 8.0mm max. width, and 42.0mm max. height, with 30+/-3mm UL3302 30AWG wires and a MOLEX/510210200 connector.

Its protection circuit uses an S8261DAA-M6T1U protection IC and 8205 MOSFET, supporting over-charge, over-discharge, over-current, and short-circuit protection functions according to the PCB specification. VTCBATT supplies this lithium polymer battery pack for OEM/ODM projects, sample development, connector and wire matching, label customization, factory-direct batch production, and battery wholesale programs for device manufacturers and distributors.
