Charging 24V system

[lowenbrau]

So conect one jumper to + on battery 1 and one jumper on + to battery 2?

right?

Well if by the first 'one jumper' you mean the cable that is connected to the + terminal of the running vehicle or charger and you identify battery 1 as the high battery ( a meter shows +12v to gnd on the - terminal and +24V to gnd on the + terminal) and you mean the second "one jumper" to be the cable that is connected to the - terminal of the running vehicle or charger and battery 2 is how you have identified the low battery ( a meter shows 0V to ground on the - terminal and +12V to gnd on the + terminal) then uh, yeah I guess you're right.

It seems easier to me to connect + to + and - to -

so if I am using my power box, I just put the jumper cables on the high battery just like I would if it was a 12v truck, right?

If by "power box" you mean the main ac electrical panel in your home and by "just like I would if it was a 12v truck" you mean connecting the red cable to the + terminal and the black cable to the engine block then, no that wouldn't be right.
