Two batteries on one charger...request for advice. Answered
Need some advice...
I busk using a Fender Amp Can and a head set mic. The Fender amp can is a complete unit with speaker, amp, battery and charger (15v 400mha). The headset mic I run off a separate 12v SLA battery.
I currently open up the Amp Can disconnect the internal battery, attach the external battery and charge it, then put the whole unit back together. I want to make an external terminal to connect the external battery for charging and this should be simple enough says I...hmmm...So I am canvassing for second opinions regarding possible problems and whether I should set the batteries in parallel or series?
The Amp Can is an awesome little unit and Fender have stopped producing them so I don't want to do it any harm.
I know I could just buy a separate charger for the battery but that would be more crap for me to carry and I don't have the $25 to spare just now...it would also be lame...
Thanks for listening,
