Lithium Ion Polymer Battery - 3.7v 1100mAh

Regular price $14.95

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 1100mAh.

Note: due to postage restrictions, lithium polymer batteries can only be sent by road, unfortunately this means there is no express shipping option for these.

This is a normal discharge battery, and NOT a high rate discharge battery. It is NOT suitable for RC cars, planes, drones or other devices that require high power(current) for a short time. They are for applications that run for a long time(days to months) on a single charge, like portable electronic devices, dash cams, cameras or similar devices. The main difference between a high rate LiPo and normal LiPo is the discharge and charge performance. This battery has a continuous discharge rate of 1C, where a high rate battery has a continuous discharge rate of 5C, 10C, 15C, 20C, 25C, 30C 40C, 50C or higher.

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.


The JST-PH 2mm connectors are often just referred to as “2.0mm JST Connectors”. This is a generalisation of a specific product from JST, a Japanese company which make high-quality connectors. This connector is their PH series polarised connector. It has the advantage of being compact, durable, and difficult to connect backwards. Another feature, which can be an advantage or a disadvantage, depending on how you look at it, is that the JST connector is very hard to disconnect (although a carefully applied diagonal cutter can be helpful!) once it’s mated. While this makes it unlikely to fail during use, it
also means that disconnecting the battery for charging can damage the battery connector.

This connector is widely used for single cell lithium-polymer ion batteries. For example, most single cell lithium-polymer ion batteries from Sparkfun use this type of JST connector, and many of their boards include it as a power supply input. 

This connector is compatible with the power connectors on the Logomatic v2 serial SD datalogger and uLog 3-channel datalogger, with the red wire connecting to + and the black to −.
