Hello. I've been building these little battery powered practice amplifiers. I was using switched DC jacks to take the battery out of the loop when a power cord is plugged in. However, i want to move to rechargeable batteries.
I have 10.6v Ni-Cad battery packs. Last year a kind gentleman on these forums posted a constant current charging schematic specifically for my needs. I built that circuit and it works well. However, i'm confused on how to integrate it into the design in such a way that the batteries will charge while the amp is plugged in and in use.
Should i wire the DC jack to the battery charging circuit, which then outputs to the battery and then to the amp, with a current limiter between the battery and amp circuit?
Thanks for your time!
