WARNING: Not to be confused with Sterling PCU models (Sterling Pro Charge Ultra Battery Chargers)
4 stage battery charging. The B2B charges batteries between 5-20 times faster than a stand alone alternator
OEM lock: the unit can be locked by the installer to prevent tampering and misuse of the product by the operators. By locking the BB, you secure all previous settings in place and prevent subsequent tampering
Unit is current limiting, prevents large current flow and requires less cable thickness
B2B turns on at 13.6V and turns off at 13.3V (x2 for 24V). Thus, does not drain input battery. Regenerative braking mode shall allow the input voltage to drop to 12.2V (x2 for 24V).
