Ansmann 2S2P Li-Ion batériový pack 4x 18650 s káblom 7,2 V 6700 mAh (2447-3043-40)

This ANSMANN battery pack uses a 2S2P configuration of four 18650 lithium-ion cells, delivering 7.2 V and 6700 mAh without the weight or memory effect of older chemistries. It is supplied with open wire ends and a JST-XH balance connector, so it can be integrated into custom devices or replace packs in compatible equipment.

Highlights

• 2S2P arrangement: two cells in series and two in parallel for balanced voltage and capacity
• Integrated PCB protection against overcharge, over-discharge, short circuit and overcurrent
• Open wire ends for flexible connection, plus a 3-pin JST-XH balance connector
• Shrink-wrapped housing keeps the pack compact and lightweight

In daily use

The pack supports a maximum continuous discharge current of 13.4 A (2C) and can be charged at up to 6.7 A (1C). It operates in temperatures from -20 °C to +60 °C during discharge and 0 °C to +45 °C during charging, with a cycle life of more than 500 cycles to 80 % capacity.
