OK so I purchased 2 2013 Brammo Empulse units. One which is like new with 3400 miles has been rebuilt as a reverse trike (zener-ecite) the 2nd is a damaged one I purchased just for the battery pack. My plan is to pull the batteries out of the 2nd and install them in parallel with the battery on the trike. I can see how the power out will work fine however am unsure as to how charging and balancing will be achieved. Any incite on this would be appreciated.
