The new Triton field charger from Great Planes is an excellent charger. It able to Fast Charge, Discharge, and Cycle. It will do NiCd, NiMH, Li-ion, and lead acid batteries(field box). You will need to purchase a table top power supply for home use. A 12 volt 10 amp power supply should be great for most needs. Pyramid makes some very cheap power supplys around 50 bucks.
