BRAND NEW PRODUCT


The Sterling Power Pro Batt Ultra DC to DC battery to battery (B2B) chargers take battery to battery charging, or "Echo Charging",  to a whole new level.

The Sterling Power Pro Batt Ultra BB123670 is a 12v 70A input to 36V 23A output fully independent buck (drop voltage) or boost (increase voltage) 36V 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 BB123670 can then send the Start/AUX/Windlass/Thruster battery either a higher or lower voltage than the house bank requires. These units can also independently float the start, windlass or thruster battery, even before the house bank has entered float.

The BB123670 is perfect for charging a 36V bank from a 12V bank using a fully independent 4 stage smart charging. This is a true smart battery charger that charges from one 12V DC battery bank to a 36V DC battery bank.

Important Features:

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 BB123670 turns on at 39.3V and turns off at 39.0V.

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 BB123670 can also equalize your 36V battery bank when required.

Very Simple to install: No complex wiring

Battery Temp Sensor:  The BB123670 comes standard with a remote on-battery temp sensor.

Optional Remote Control:  The BB123670 can be fitted with an optional remote control model # BBURC.
