This custom lipo battery for your polarstar is barely larger than the standard, low quality 250mah lip0s, and has almost double the capacity! The longer, thinner design fits far better in buffer tubes and under AK dust covers than the current “brick” style models. Wired to JST and a standard balance plug. Comes charged and ready to go!
Makes a perfect filler for free shipping orders! Wires are 2.5 inches long. If you need longer wiring, check out our extended wiring batteries HERE.
We are not responsible for puffed or dead batteries due to incorrect charging, or letting them discharge to far. All batteries are charged and tested before they are shipped.
