I need some help figuring out how to charge my robot's 12v lead battery without taking it out of the robot.
This seems to be what should be done, but it's REALLY over my head:
I've seen people on the astromech forum mention that they simply added a switch to cut off the electronics from the battery when recharging.
So I've got some questions:
- Is there an easier way to do what I want without putting in a manual switch?
- Is it necessary to isolate the electronics from the battery when charging?
- If I do simply put in a switch, is putting it on the positive wire enough? I presume nothing needs to be done with the black / ground wire.
thanks in advance,
