The Sterling Power 12V DC to 24V DC battery to battery chargers take battery to battery charging, or "Echo Charging", to a whole new level.
The Sterling Power BB122470 is a 12V to 24V charger with 35A of output at 24V! It is a fully independent 12V to 24V smart battery charger. This means the voltage input battery,
most often the house bank, can be programmed for it's own optimal
charging voltage and the Sterling Pro BB122470 can then send the
Start/AUX/Windlass/Thruster battery its own optimal charging profile.
Imagine you have a 600Ah GEL
house bank that needs to be charged at 14.1V and a 24V Odyssey TPPL AGM bow thruster or windlass battery that needs 29.4V. The Sterling BB122470 can do
this! The BB122470 can take an input voltage of as little as 13.3V and
boost the output to 30V +, depending upon the charge voltages chosen.
BB122470 is perfect for charging a 24V thruster or
windlass bank with fully independent smart temp compensated charging.
The Sterling BB122470 is a true smart battery charger that charges from one DC battery bank to another DC battery bank. It does not need 120V C or 240V AC power to operate it simply charges from one 12V DC battery bank to the target 24V DC battery bank.
Sterling battery to battery chargers are ideal for charging from 12V to 24V.
Multiple Activation Modes: Automatic or Manual
Dedicated Voltage Sense Terminals:
For those long bow bank runs where voltage drop can be an issue, the
BB1260 features dedicated non-current carrying voltage sense leads for
accurate sensing of battery terminal voltage.
Step-up options: Fully programmable including custom options and absorption duration customization
Boost / Reduce Charging: The B2Bs ensure batteries get the correct charging profile irrespective of high or low input voltages.
Auto On/Off: The BB122470 automatically turns on at 13.3V and turns off
Profile Customization: Select your own charging profile on the front panel or build a custom charge program.
9 Preset Battery Voltage Options: Profiles for AGM, LiFePO4, Gel, Flooded and more.
4 Stage Battery Charging: Bulk, High Absorption, Low Absorption & Float / Maintenance
Equalization Mode: The BB122470 can also equalize your 24V bank when required.
