The Most Advanced DC to DC Chargers You Can Buy!
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 BB1260 is a 60A fully independent buck (drop voltage) or boost (increase voltage) 12V 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 BB1260 can then send the Start/AUX/Windlass/Thruster battery either a higher or lower voltage than the house bank requires.
Imagine you have a 600Ah GEL house bank that needs to be charged at 14.1V and a Odyssey TPPL AGM start or windlass battery that needs 14.7V. The Sterling BB1260 can do this! The BB1260 can take an input voltage of as little as 13.3V and boost the output to 15.1V, depending upon the charge voltages chosen.
The BB1260 is perfect for charging a starting, reserve battery or a windlass bank with fully independent smart charging, not just voltage following of the house bank..
The Sterling BB1260 is not just a simple "voltage follower", like the Xantrex Echo Charger, it's a true smart battery charger that charges from one DC battery bank to another DC battery bank.
Sterling battery to battery chargers are ideal for charging windlass banks too.
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 BB1260 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
