So, I have this new to me Aaton 35-III cam and it uses 12V onboards with XLR connectors. Can't really find the original charger for these, so I thought I'd perhaps adapt my own. Camera takes 10-14V, so I'm assuming the best would be to find a 14V charger to charge the batteries with, right? I'm a bit clueless when it comes to electrical stuff, but I seem to recall from my science classes that to charge something to 12V, the charger needs to be more than that. So, here are some questions:
1. For a 12V battery, would 14v charger be best?
2. Would it charger quicker with a higher voltage, i.e. a 16V charger? Would I risk blowing something?
3. What would a good amp be for the charger, so I don't blow them up? They're probably around 20-40Wh these batteries. What's a good rule of thumb here?
Appreciate any insights.
