Series/parallel charging question for les tinkerers grandes

did you buy a "true charge" with (2) outputs ?

then yes you can charge each battery separately, because it will monitor each battery, but you need to remove /disconnect the (inter connect) cable between A- and B+ when connecting the true charge

sorry about your cat..

but erroneous battery statements need to be corrected

using "individual" separate chargers will not be balanced and equal
