I have 48v system of 4 identical 12v 50ah batteries hooked in series (wheelchair deep cycle types). but to recharge, I break the clip link in the center, this gives me essentially two 24v series battery packs, I then hook up a used 24volt wheel chair battery charger to both packs at once....works great, auto shut off when topped up
if all your cells are identical you can charge them this way....doesn't work well to have disimilar 12v hooked in series, the charge won't evenly bring up both batteries and may stress the smaller one (so I've been told)

Subject: [Electric Boats] Charger Replacement Recommendations?
I have an Ericson 30+ with a Thoosa 9K motor. My only charging is done with shore power. My charger, a QuadPro has died. Well, half-died It's 4 12V chargers in a package, and 2 out of 4 are dead.
What do people here like for replacement? Another QuadPro? Something that instead would charge the whole 48 bank instead of charging each 12V battery separately? (Battery is made up of four 4D 12v 198 Amp Hour AGMs.)
I would like to maximize options like adding solar or running off a portable generator like Bianka does. Does that impact my charger options?
The general topic of charging the whole 48V bank versus each battery? If you do that do you use a separate 4 bank charger for equalization?
