Batteries and Charging

Driven by the wind, powered by the sun, steered by the wind. Sail now

Batteries

The boat is fitted with two battery banks. The start battery is a 70 AmpHr Bosch  (July 2020) The house bank is two 120 AmpHr  Leochs (July 2020)

Charging

The engine is fitted with an 80 Amp alternator that charges the batteries through a Voltage Sensitive Relay (VSR (2016)) ( All the charge from the alternator goes initially to the start battery: only when that reaches the required voltage does the charge go to the house bank)

Each battery bank is fitted with its own hard wired mains charger. The start battery has a CTEK XS 0.8 (2016) and the house batteries a CTEK M200 (2016)

There are also two 100 Watt solar panels. (2016) Each is connected through a Victron MPPT solar controller, (2022)  one to the start battery, one to the house bank. When the start battery reaches the required voltage the VSR directs the charge from the start battery into the house bank. The two Solar Charge controllers will Bluetooth their charging information to an App.

There is a (two bank) Victron battery monitor (2016) showing battery status. The house bank is “Main” and the start battery is “Aux”. The Victron provides a variety of data about the “Main” and the voltage of “Aux”
