BU4 is an intelligent charger, which combines convenience and fast charging into a single unit.
Charging times depend on each batteries current capacity, although the independent output (1A, 2A) and pulse charging circuit are compatible with any cylindrical Li-ion batteries (3.6/3.7v), Ni-MH and Ni-Cd batteries ranging in size between 10440 up to 21700. The BU4’s 3 LED display allows for clear viewing of the current charging status.
