We have developed a new battery management board capable of supporting up to 48V, so these batteries can be put in 12V, 24V, 36V, or 48V combinations by placing them in series. This is helpful in electric bikes, wheel chairs, and other higher voltage appliances. They can also be put in series-parallel combination, just like sealed lead acid batteries. Before putting them in series it is best to fully charge each battery at 12V (14.6V peak) to make sure they start out balanced.Â
