BATTERY CHARGING AND MANAGEMENT WITH THE BATTERYPLUS35-II
The BatteryPlus35-II can deliver up to 35A to simultaneously power loads and charge
the caravan battery, with a maximum charging current of 20A for the BP35-II-SI and
BP35-II-SR and 30A for the BP35-II-HA with the difference being reserved to supply
12 V loads.
The maximum charging current will be reduced if the loads present are drawing
significant current and as the battery approaches full charge. To ensure that the
caravan battery is charged by the maximum charging current, switch off non-
essential loads.
Auxiliary Charging
When charging from auxiliary, the BatteryPlus35-II monitors the battery voltage
level and charges as needed. Auxiliary charging is commenced only when the
auxiliary voltage exceeds the battery voltage by at least 0.5V and is greater than
12.6V.
Mains Charging
When charging the battery from mains, the BatteryPlus35-II applies a multi-stage
charging algorithm. Further details can be found in the Appendices.
Solar Charging with the BatteryPlus35-II-SI
When charging the battery from solar, the BP35-II-SI applies a multi-stage charging
algorithm.
The BatteryPlus35-II (SI) will use solar as a charging source if the voltage generated
by the solar panel is greater than the battery voltage.
Solar Charging with the BatteryPlus35-II-HA and BatteryPlus35-II-SR
When charging the battery from solar, the BP35-II-HA and BP35-II-SR applies a
multi-stage charging algorithm.
The BatteryPlus35-II (HA and SR) will use solar as a charging source if the voltage
generated by the solar panel is greater than 17.5V for at least two minutes.
WARNING
Do not attempt to charge non-rechargeable batteries. Charging a non-
rechargeable battery may result in the battery catching fire or possible explosion.
