The Sterling Power BB484830 is a 48V to 48V DC to DC charger for moving energy safely between two separate 48V battery banks, lithium or lead acid. Think of a large rack battery topping up the smaller 48V packs in an electric boat, vehicle, robot or off-grid setup.
Joining two 48V banks directly is risky: if one is flat and the other full, the rush of current can trip a battery's BMS and nothing charges at all. The BB484830 limits the current to 30A and applies the correct charge voltages across a 39-60V DC range. It can be switched on by any 8-80V ignition signal, or by a selectable vibration-sense mode that wakes it when the vehicle is moving.
Features
- Current limited, so mismatched 48V banks can be connected safely
- Correct charging voltages for lithium or lead acid 48V banks
- Ignition feed activation from any 8-80V signal
- Selectable vibration-sense mode
