Victron EnergyBattery Balancer

When the battery goes over voltage does the unit move the power to a lower voltage battery or does it just dissipate the power in the heat sink?

Can this be used to balance my 24v lithium battery that is made up of 8 x 3.2v series-connected cells?

Do connect the 4battery bank with the 4/0 cable (I use 4/0 ) or do you connect with 18 awg wire, which is min. spec. of wire connect battery balancer?

Will this protect both the starting (lead acid) and an auxiliary lipo battery. will it protect the alternator?
