 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.
