Batt Ultra Battery to Battery Charger

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 profle with a very simple and speedy installation.  All of the benefits of advanced charging without any of the drawbacks.  Simply connect the B2B between the battery being charged and the battery you wish to charge.

WARNING: Not to be confused with Sterling PCU models (Sterling Pro Charge Ultra Battery Chargers)

4 stage battery charging. The B2B charges batteries between 5-20 times faster than a stand alone alternator
