BB1270R

Reverse Charge permanently on -- all other functions the same.

Requires ignition feed to operate the BB1270 in the normal direction. Once ignition feed is off (0V) the BB1270 shall remain in reverse charger. 

This is idea for those that want to keep their starter battery at 13.4V constanstly. N.B. this shall use a small amount of power from leisure battery.

 Paralleling multiple battery to battery chargers together?

There are no problems installing multiple BBs together in parallel to increase the power. For example, you can parallel a BB1240 with a BB12120 to get 160A of charge current. Likewise, BB1270 w/ BB1240 or BB12120 etc.. it does not matter.

Benefits:

1) Redundancy, having multiple DC-DC chargers can help with reduncancy. If one was to get damaged, the other BB(s) shall continue charging.

2) fine tuning the current. As each BB has 3 different power levels, adding multiple BBs together gives you 6, 9, 12 etc.. different power levels. For example, if you wanted 90A you could get a BB1270 and a BB1240 and set the power levels to 85% each via the BBR remote (to give you approximately 90A). Thus, giving you large levels of flexibily to hone in to a specific charge current.
