 Battery to Battery Charger Remote Control - BBR

PLEASE NOTE - BBR works best with brand new models in stock now (June 2022 onwards). If you have a BB1240/70/120 from before this date, you may have to send the BB back to use for latest firmware. As this is a new item, it has features that require BB firmware modifications.

(Optional)

BBR comes with 4m extension cable

What does the BBR offer?
- Live voltage and current readings from BB output
- Ability to set custom charge profiles | absorption, float and absorption time length
- Ability to adjust current limit to 85%, 65% or full power (100%)
- Allows the removal of float voltage feature in lithium profiles
- Desulphation / equilisation settings can be set in LEAD modes.

 

Why adjust the current limit?

The default current setting for the BB range is 100% - meaning that the performance default is full power. If you wish to reduce the performance of the BB, here you can set to 85% or 65% charge rate. Examples of why you may wish to reduce performance:
1) if you have solar panels and the weather is good, by reducing the power of the BB, you shall conserve fuel.
2) The alternator is better suited running at slightly lower current than what was expected.
3) It may be recommended by your battery supplier to charge the battery up at a slightly lower current. If one of your lithium batteries within your leisure battery bank fails, you may be exceeding the C rating of the remaining batteries.
4) future proofing. If you have installed a high powered BB, in the assumption that one day you shall put a larger alternator on and/or more batteries in your system. You can reduce the power for the immediate install and increase the performance of the unit at a later date.

 Instructions

 

 

 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.
