True.

Nah, just add a little switchable resistance to the charging circuit, just
enough to cut the charging current in about half. On 240, charge normally. On
120, flip the switch to insert the resistance. A battery disconnect switch
should work fine. Just arrange it to short the resistor.
What pack voltage and charging current are you using? We can figure out a
resistance from that.
OR
Does the Zivan have an adjustable current limit? Maybe an internal pot? If
it does, arrange for two pots and a switch. One pot is set for normal 240
operation and the other is set to half current for 120.
