Product details

STERLING battery-to-battery chargers allow the charging of an additional battery (e.g., bow thruster or windlass batteries) and ensure that the primary battery (e.g., the starter battery) is not unintentionally discharged. As soon as the voltage on the primary battery reaches more than 13.2 V, the secondary battery begins to charge. Very simple installation, since the existing system usually doesn't have to be changed.
  • Compact, lightweight design
  • IUoUoU
  • Adjustable for 8 common battery types
  • Also suitable for Li-Ion batteries
  • Separation of battery banks
  • Automatic activation
  • Incl. temperature sensor
  • Remote control is available as an accessory

It's becoming a habit....
The Sterling is still awaiting installation. Always remarkable The quirky 1960s design of Sterling appliances. But they do their job - at least the ones already installed.

Unique product to charge your household battery on board via your starter battery, while motoring. An earlier version of Sterling has operated on a previous boat for 11 years without problems.

Old stock?
The unit's plastic packing looks dated and its test report is from 21 July 2018! So it looks like old stock being sold.
