Custom LiPo Battery LP475085 3.7V 2500mAh

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 2500mAh for a total energy about 9.25 Wh. If you need a larger battery, we also have a 3000mAh+ model

The LiPo batteries come pre-attached with a genuine 2-pin JST SYR-02T/02TY & SYP-02T/02TV-1 connector as shown and include the necessary protection circuitry. It’s a better solution of wire to wire connector with higher current and voltage, not a knock-off, the cable won’t 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 1250mA or less.
Like most lipo batteries we sell do not have thermistors built in. This is why we suggest charging at 1/2C or even less – 1250mA max in this case 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 LiPo batteries, do not short, bend, crush or puncture. Never charge or use unattended. Always inspect LiPo batteries and surrounding circuitry constantly for any damage, loose wiring, or the possibility of short circuits. Polarity matches all Adafruit LiPoly/LiIon chargers and boards, other brands may have reverse polarity and can destroy your battery. As with all LiPo batteries and with any power source – they should be used by experts who are comfortable working with power supplies.
