Lithium-Ion Polymer Battery - 3.7V 400mAh

Lithium-ion polymer (also known as 'lipo' or 'lipoly') batteries are thin, lightweight and powerful. The output ranges from 4.2V (when completely charged) to 3.7V. This battery has a capacity of 400mAh. If you need a battery with different capacity or size, we have a full range of LiPoly batteries.

The batteries come pre-attached with a 2-pin JST-PH connector as shown and include the necessary protection circuitry.

Additional safety notes: it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge the battery at a rate of 150mA or less. Do not use a NiMH/NiCad/lead-acid charger. Also, do not abuse these batteries, do not short, bend, crush or puncture. 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.
