battery charger mods
« on: April 26, 2009, 11:34:31 PM »
Is there a way to change the output voltage of a battery charger?

I'm not talking about the variable output voltage chargers, but cheap regular ones. As an example, can I recircuit an old laptop charger to charge a 36v or a 48v battery?

Supposing the that current is not an issue (since the current output is similar in laptop battery chargers), I would simply need to change out a particular resistor or the LM piece right?
