POWER / LIION & LIPOLY / BATTERIES / LITHIUM ION POLYMER BATTERY - 3.7V 350MAH
DESCRIPTION
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
350mAh for a total of about 1.3 Wh. If you need a larger (or smaller!) battery, we have a full

TECHNICAL DETAILS
range of LiPoly batteries.
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 350mA or less. We suggest our Micro Lipo charger, which has a 100mA default
rate.
Like most lipos, the batteries we sell do not have thermistors built in. This is why we suggest
charging at 1 C or even less - 100 to 350mA is a good rate, and available from any USB port if
using a USB-powered charger
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. Never charge or use unattended.
Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring,
or 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 Lithium ion
polymer batteries and with any power source - they should be used by experts who are
comfortable working with power supplies
