NEW PRODUCT – Lithium Ion Battery – 3.7v 2000mAh


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 2000mAh. If you need a larger (or smaller!) battery, we have a full 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 150mA or less. We suggest our Micro Lipo charger, which has a 100mA default rate. You can also set the Micro Lipo to 500mA rate for a faster charge.

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 500mA 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. 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.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. “it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 150mA or less. We suggest our Micro Lipo charger, which has a 100mA default rate. You can also set the Micro Lipo to 500mA rate for a faster charge”.

    Is the “rate of 150mA or less” “very important”, or will 500mA work for a faster charge without pyrotechnics?

  2. we suggest 100mA/500mA since its what you can get from USB. Quick charge is OK too – check DS!
