Key Features

  • Made of 2 balanced 2200mAh cells totaling a 4400mA capacity
  • Genuine JST connector
  • Not intended for high loads - keep contstant draw under 1A

Need a big battery for your project? This lithium ion pack is made of 2 balanced 2200mAh cells for a total of 4400mA capacity! The cells are connected in parallel and spot-welded to a protection circuit that provides over-voltage, under-voltage and over-current protection.

Each cell can provide 1A of current for about 4 hours so all together the peak current you can draw is a little over 1.5 Amps. Note that these batteries are not designed to sustain such high loads, we suggest keeping any constant current draw under 1A.

The packs come with color coded wires, and now they come with a JST 2-pin cable attached for use with our chargers! Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly. The cables are rated for 2A so if you use them keep that in mind.

The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 2.5V. However, even with this protectioit is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 0.5C (2.2A) or less.
