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 BB241235 is a 24v 35A input to 12V 70A output fully independent buck (drop voltage) or boost (increase voltage) 24V 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 BB241235 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.

Imagine you have a 600Ah 24V GEL house bank that needs to be charged at 28.2V and a 12V Odyssey TPPL AGM navigation electronics bank that needs 14.7V. The Sterling BB241235 can do this! The BB241235 can take an input voltage of as little as 26.4V and reduce output to your 12V bank. It can even equalize the target bank!

The BB241235 is perfect for charging a 12V bank from a 24V bank using a fully independent 4 stage smart charging. This is a true smart battery charger that charges from one 24V DC battery bank to a 12V 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 BB241235turns on at 26.2V and turns off at 26.0V.

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 BB241235 can also equalize your bow or start battery when required.

Very Simple to install: No complex wiring

Battery Temp Sensor:  The BB241235 comes standard with a remote on-battery temp sensor.

Optional Remote Control:  The BB241235 can be fitted with an optional remote control.
