All-in-one Power Management System for your caravan
BatteryPlus35-II-SI is a complete Power Management System designed specifically for recreational vehicle applications. This all in one power solution combines a 35A power supply for 12V loads, 20A multi-stage AC charging and 20A Solar PWM regulation as well as a host of battery protection features. For more robust solar capability, choose a BatteryPlus35-II-SRÂ with an inbuilt 30A Solar MPPT regulation.
Connect the unit via CAN bus to the Trek battery monitor or to Odyssey touch screen via the OdysseyLink to monitor the status of your battery and to control your caravan features and functions or use it to connect to the BC300 to monitor high currents via CommLink.
Connect solar panels to the solar Power Management System and power your adventures with renewable energy.
BatteryPlus35-II-SI is pre-cabled with a permanent mains power supply cord for use with 240V or 110V input power – great for powered sites.
The unit also features a 40A rated uncontrolled +BRK battery output. This output is specifically designed for loads which do not need to be isolated or have a current rating of higher than the inbuilt circuit protection of the individual outputs and have a current rating less than 40 A.
Use it to connect, for example:
• Proactive Electronic Stability Control SwayControl
• Emergency Trailer Break-Away Safety System TrailSafe
• Heaters
• Stereo memory
For Lithium Ion batteries, check BatteryPlus-II-HA high amperage Power Management System featuring a charger with lithium profile.




Upgraded from old Battery Plus 35 and was easy to install. Very happy with it.
With a voltage of 12.2v it’s only charging at 7.5A & output of 6.6A
Fantastic support from the team. Our issue turned out to not relate to our BMPROplus35 unit at all. That unit was found to be working fine. However, for us amateurs to discover this, took a lot of time and support from the tech support team in Melbourne, over a few days. Thank you Steve so much for your courtesy, amazing patience and quality guidance, especially in these trying times of lockdown. Much appreciated. Jackie and Nigel.
