Portable Homemade TV Answered
I built a TV from an old laptop screen and one of those LCD control boards you can get from eBay but I’m curious how to go about adding a battery to it to make it portable. So, my question is, how do I go about battery safety and how do I control charging and isolation? For example, if I plug the TV in because the battery is dead, do I just have a charging board between the input and battery and let the charging board take care of the rest? And the same question is applied to when the battery is at peak charge but I don’t want to use the battery just simply plugged in. The battery is a 12v 2A lipo and I don’t want any fires.
I’ve thought about adding a switch to simplify things but that’s inconvenient and armature
I could make a circuit that would cut off the flow when the battery is at peak I suppose but I’m not sure of the schematics or if that is the right approach.
I’m good at building just not figuring this stuff out….
