Lithium polymer or as many call them lithium-ion polymer batteries are the preferred power sources for most electric RC models. They offer high discharge rates and a high energy storage/weight ratio. We stock the largest range and the highest quality Lipo (li-Poly) batteries, varying in capacities and voltage. No matter what your RC hobby is we’ve got you covered. Our range includes Graphene, Nano-Tech, MultiStar, Turnigy, Zippy and much more. One thing you need to keep in mind LIPO batteries do not like being over discharged and can even break if discharged too much. It doesn’t really matter what kind of LIPO checker you get, but the HobbyKing LIPO to USB charging adapter and cell checker is ideal because it can also turn your battery into a Phone charger!!
