This single-cell Lithium-Ion battery is compatible with the Open-Q™ 835 HDK and Open-Q™ 660 HDK and can be purchased as an optional accessory. The HDK kits have a battery holder and mating connector on the bottom of the carrier board but do not include the battery by default.
Specifications: Nominal V = 3.85v Capacity = 3100mAh
Note about shipping: Separately shipped Lithium-Ion batteries must be shipped by ground and therefore will take longer than usual to arrive. If a battery is ordered with a development kit, it will be installed in the product before shipping and can therefore be shipped by air.
