Estimated shipping time: 2-4 weeks
Sterling Power DC Battery to Battery Charger 12V Input/24V Output DC to DC converterCharge your auxiliary battery bank with the correct multistage, temperature-compensated charging curve by using the input power of any vehicle's alternator thru the start battery system automatically while the vehicle is running. 12v input at up to 70 amps, and output is 24v at up to 35amps.
Simply connect in between a starting battery and house bank, and any time the vehicle's alternator is running, this smart charger will smart charge the output bank. Preset Charge Profiles and one user customizable profile are available.
Sterling's range of Battery to Battery Chargers (B2Bs) has grown significantly over the past few years. This is in an effort to supplement the ever-growing demand from the commercial vehicle, recreational vehicle and marine industries.
The B2Bs have become extremely popular as they fast charge batteries as you cruise along without the need for complex wiring, touching your alternator, voiding the alternator's warranty and tampering with the electronic control units (ECUs). You can provide the onboard batteries with a fast 4-stage charging profile with a very simple and speedy installation.
All of the benefits of advanced charging are without any drawbacks. Simply connect the B2B between the battery being charged and the battery you wish to charge.
Multiple Activation Modes: Automatic for most non-vehicle applications,
- Manual for remote activation.
- Regenerative braking (requiring ignition feed),
- Automatic regenerative braking, requiring no ignition feed.
Input 12v & Output charging at 24V
Much larger model up to 3000W coming soon
Current is NOT taken from the input battery and given to the output battery
The B2B uses alternator power to charge the output battery. Manual mode and regenerative braking mode allow you to override this.
- 100% fireproof plastic box.
- No screws to corrode.
- Thermal power reduction.
- Multi-stage fan cooling.
- The internal heat sink temp is between 158 – 180F. The unit shall drop to half power by this point – additionally reducing temperature.
Night Time Setting
Allows the unit to run at half the power, so the fan noise is kept down.
Boost / Reduce Charging
The B2Bs ensure batteries get the correct charging profile irrespective of high or low input voltages.
B2B turns on at 13.3V and turns off at 13.0V (x 2 for 24V)
Thus, does not drain the input battery. Regenerative braking mode allows the input voltage to drop to 12.2V (x 2 for 24V).
Choose your own charging profile on the front panel.
9 preset battery chemistry options
Including AGM, LiFePO4, Gel, Flooded and sealed lead acid.
4-stage battery charging
The B2B charges batteries between 5-20 times faster than a standalone alternator.
Very Simple to install
No electronic Control Unit (ECU) issues. No complex wiring. No warranty issues. Fully prepared for smart alternators (regenerative braking).
