Sterling Power

Sterling Power builds battery-charging and power-management electronics for van, marine, and overland builds where a simple relay won’t do. The range centers on the Saturn series of bidirectional battery-to-battery DC-DC chargers: intelligent, multi-stage units that turn your alternator into a fast, controlled charge source for lithium, AGM, and lead banks, with jump-start assist, six battery profiles, and full smart-alternator (Euro-6) support.

Alongside the DC-DC range sit alternator-to-battery chargers, Pro Charge Ultra mains chargers, alternator protection devices, and remotes. Every unit is engineered in the UK, conformal-coated, and backed by Sterling’s factory warranty. The lineup runs from 25A to 200A — size the charger to your battery bank’s recommended charge rate and your alternator’s rated output before you buy.
