Series 12v Chargers ?
Bestconverter ad says, "The PD9100L Series can be wired in parallel to charge at much higher current rates. They can also be wired in series/parallel to charge 36, 48, 60, 72 and higher voltage bat...

Anytime you expect more amps than the charger rating the voltage sags. So if the 100a starts pushing more than the other charger is rated the other charger voltage will drop off and limit the amps.
Basically if you have the 55 and 100 in series then anything above 55 amps will cause the output voltage to sag from the combined set point (29.2v) to something less as dictated by the battery.
This is exactly the same effect as when charging at 12 volts. If the battery wants 100 amps but you only have 55 the voltage sags and we call that bulk as the charger is maxed out.
Or another way to look at it is that anything above 55 amps the 100 amp charger is on it's own and of course set at 14.8v those extra amps go nowhere into a 24 volt battery.
