Couldn't load pickup availability
This 11.1v Lithium-Ion battery is a very slim, extremely lightweight battery based on the new polymer lithium-ion chemistry. This is the highest energy density battery currently in production. Each cell outputs a nominal 11.1v. These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium-Ion battery charger.
This Li Ion Battery includes built-in protection against over-voltage, over-current, and minimum voltage. Please use caution when using this battery in wearable projects. A short in the thread can create sparks and heat when using conductive thread.
