All DCS dual battery systems (DBS) are supplied with the fully programmed Victron Smart Battery Protect’s which are a load disconnect. This device is what governs the reserve for engine starting. Very efficient only drawing 1.2mA when engaged. We recommend to use the top 80% for deep cycling for accessories and the remaining 20% is reserved for engine cranking. The SBP’s should be installed inside the cabin and you should be protecting as many of your light loads as possible, USB sockets, fridges, lighting, dash cams, UHFs, Cel-Fi’s etc.. Inverters over 300W must be wired directly to the batteries bypassing the SBP’s.

With two of the DCS 130Ah Hybrid batteries connected in parallel you can charge up to a maximum of 125A x 2, so 210A. So ideally keep alternators under 210A. All DCS batteries feature high performance cylindrical cells, and this mechanical design is very efficient so it’s very easy to recharge these batteries, there is no need to install larger alternators, OEM alternators are the best for our batteries and will charge them back up very fast. If your running a vehicle with a lazy smart alternator focus on installing a quality commercial solar panel something at least 360W. Which will easily keep the batteries topped up when running a standard sized fridge.

This system is suitable for just about every make/model of 4WD on the market that can accommodate these sized batteries under the bonnet or of course in the cabin if one so wishes.
