Specifications:
The Kokam lithium polymer electric battery packs are composed of 1,2, or 3 cells wired in series utilizing a sturdy internal printed circuit board. There are three different connector types supported. The connectors are configured to support the current requirements of cells based on the capacity of the pack. Small, low capacity packs include a tiny polarized 1.25mm connector. Medium capacity packs include a polarized 3mm connector with a locking tab. High capacity packs include a Deans Ultra connector. The connector wire is strain relieved using heat shrink material that encloses and protects the assembly. Lithium polymer technology provides extremely high capacity in an ultra-low weight package. Packs are available in all standard capacities. It is recommended that you size the packs according to the current draw requirements of your electric propulsion system.
Unlike any other battery chemistry, Lithium batteries are designed for parallel or series/parallel operation. In choosing your configuration, first assemble cells in series to achieve your voltage requirements. Next parallel multiple series packs to increase your capacity. Other than size, there is virtually no limit to the current capabilities of a series/parallel LiPo battery. The more cells you parallel, the more current you can draw from the battery pack. Series/parallel packs are defined by NSXP where N = number of cells in series and X = number of series packs wired in parallel. As an example a 2S3P pack of 1500 mAh high discharge cells would be comprised of 3, two cell series packs wired in parallel. The nominal voltage of this pack would be 7.4V. The total capacity would be 4500 mAh. Running this pack at 8C means it can support 4500 mA x 8 = 36000 mA or 36A of current.
