NEW PRODUCT – Large Lithium Ion Polymer Battery – 2700mAh

Lipo2700 Lrg

NEW PRODUCT – Large Lithium Ion Polymer Battery – 2700mAh. 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 2700mAh for a total of about 10 Wh. If you need a smaller battery, we also have a 1300mAh model

The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. 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 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 3.0V. 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 1200mA or less.

Like most lipos, the batteries we sell do not have thermistors built in. This is why we suggest charging at 1/2C or even less – 1200mA max in this case. Even 500mA is a good charge rate, which is how much you can get from a USB port.

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.

  1. Can you power a 5v Arduino with this? Or just a 3.3v?
