Adafruit Li-Ion 3.7V Battery, 6600mAh

Product Description

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 at a rate of 0.25C (1.5A) or less.

Like most lithium-ion packs, the batteries we sell do not have thermistors built in. This is why we suggest charging at 0.2C or even less - 1A max in this case. Of course, you can charge at a lower rate - it'll just take a little longer to fill up.

Additional Safety

Do not use a NiMH/NiCad/lead-acid charger. Also, do not abuse these batteries, do not short, bend, crush or puncture. Never charge or use unattended. Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or possibility of short circuits. As with all Lithium ion polymer batteries and with any power source - they should be used by experts who are comfortable working with power supplies

Please note: There are some shipping restrictions when it comes to shipping lithium ion batteries. If anything occurs we will notify you as soon as we are aware of an issue with the order.

  • Color coded wires
  • JST 2-pin cable attached for use with Adafruit 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.
