NEW PRODUCT – Lithium Ion Polymer Battery – 1200mAh. Lithium ion polymer (also known as ‘lipo’ or ‘lipoly’) batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 1200mAh for a total of about 4.5 Wh.

The batteries come pre-attached with a 2-pin JST-PH connector as shown and include the necessary protection circuitry. The protection circuitry keeps the battery voltage from going to high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead. It will also protect against output shorts. 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 500mA or less.

Additional safety notes: 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.
