Hello everyone,
It may be discussed before somewhere but i could not find it..
I would like to build portabe speaker with inbuilt 3s battery pack and charge it with smart balance charger so i wanter to do little system that when i connect charger the relay would disconnect battery from amplifier but also i would have ability to use external power pack to power amp while it is charging or if decide to use external power instead battery.
So basicaly i need to automaticaly disconnect the battery from amp if charger or external supply is connected (2 separate inputs carger and external power)
So i was woundering if somebody done anything similar befor and could point me to right direction?
Sorry for my English it is not my first language..
