[PSUBS-MAILIST] Batteries

[hank pronk via Personal_Submersibles]

Alec,I charge two 6v at a time, but I do not uncouple the batteries.  I have holes drilled in my floor boards so I can connect the charger clamp to the battery terminal.  It seems to work fine.Hank

 I have what I think is a similar setup in Shackleton. There will be 12 batteries in all, with each pod having two series sets of three batteries, and the two three-battery sets being in parallel for 36 volts. 
As far as I know the "proper" way to charge would be to decouple all the batteries and charge them individually, for which you would use a bunch of charging relays to temporarily undo the battery interconnections, and a multi-output charger. However, with 12 batteries and especially considering all I have is two conductors coming out of the pod, I've concluded the "proper" way just isn't practical for me. I've got a dual output 36 volt charger and am just going to treat each pod as a giant 36 volt battery.
If anyone thinks this is a huge no-no that would justify opening up the pods and disconnecting every battery every time I charge, please do speak up!

Thanks,
Alec
