This thin, large-capacity battery is perfect for providing stable, rechargeable power in projects/systems that are power-hungry!

Unlike our other batteries, this one comes with 3 flying leads. There's the usual positive power and ground but this one also includes another lead which can be used to monitor the temperature of the battery. Using an internal thermistor the temperature of the battery can be calculated using the NTC (Negative Temperature Coefficient). Basically, the resistance decreases as the temperature of the battery increases. This makes this battery great for use in projects that have additional safety requirements or temperature restrictions. Don't worry though you can still add a 2-pin JST connector on and use it in the same way as any standard 2-pin battery.

Like all of our other batteries, this one outputs a nominal 3.7V at 3000mAh (3A) and has built-in protection against over voltage, over current, and minimum voltage.
