Adafruit Lithium Ion Battery Pack 3.7V 6600mAh

Need a massive battery for your project? This lithium ion pack is made of 3 balanced 2200mAh cells for a total of 6600mA capacity. The cells are connected in parallel and spot-welded to a protection circuit that provides over-voltage, under-voltage and over-current protection. If you need a smaller battery, or anything battery related, check out our collection of batteries and battery accessories here.  Each cell can provide 0.5C of current (1.1 A per) so all together the peak current you can draw is over 3.3 Amps. Note that these batteries are not designed to sustain such high loads, we suggest keeping any constant current draw under 0.2C or 1.3A. 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 about 3.0V. However, even with this protection it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and
