This allows the batteries to absorb equally putting less strain on the charging system.
If you are charging with an Echo Charge, Duocharge or similar it makes no difference. Commonly many have a house bank of 400AH or larger and a group 24 start. The battery is the determining factor - it accepts what it needs.
