[AT] OK, oddball question...

[Bo Hinch]

If it were me , I would use a voltage reducer like below that cost around
$100.00 dollars and draws equal voltage from ALL the batteries never making
any two batteries weaker than the others . I have installed many of them in
my life time and years down the road , it pays off big time .Reliance
36V/48V-12V Voltage Reducer/Converter (Universal Fit) on sale now from
Buggies Unlimited . Normally 174.95 , sale price is 97.95 .
Just my opinion for whatever its worth .
