Welcome to RC Battery Clinic

Many kinds of batteries are useful for the rc hobbyist. Lipo's (lithium polymer) batteries currently offer the best power to weight ratio but require special charging attention. Nicad's (nickel metal cadmium) packs are rarely used these days due to the heavy weight, low power density and environmental issues on disposal. NiMh's are still used but are becoming less frequent (nickel metal hydride). They are more green for the environment but lack the power density that lipo's or li-ion can provide. There are voltage differences to be aware of as the lithium polymer packs run around 7.2V while the nimh and nicad packs are 4.8V. Some receivers and servers are ok with the higher voltage that the lipo packs provide but please check manufacturer specs. Here is a typical lipo pack with charging red rc outpout leads. |
