Ive got a solar panel question?
Posted by admin | Under 12v Solar Panels Monday Sep 5, 2011Ok so i was wondering if it were possible to take a 12v solar panel and hook it to a 7.2v battery would it charge it or would not do anything I need answers quick thanks people.
We could speculate all day long. You’re just gonna have to try it.
yes it will charge it. You need a volt meter to make sure you don’t over charge the battery.
The place for all your answers —->>> http://www.arosaenergy.com/ I used them to install my solar panels and they had all my answers on their website. And anything more than that, they were able to answer. Just a reminder: the most accurate and honest answers usually come from the professionals.
I’ve successfully resurrected two 14.4 volt cordless drill batteries, a 7.2 volt cordless drill battery and several Versatile batteries using the easy resurrection method. It is simply amazing when the meter shows life in them again.
As soon as you connect a 12V panel to a 7.2V battery, the voltage will drop, and yes, the battery should charge. If the panel is large, there is danger of overcharging. I’m assuming this is a NiCd or NiMH battery pack. If it starts to get warm, it’s being overcharged.
The constant current of a solar panel is not particularly good for charging NiMH, so you may not get a full charge, but will get something.
All this assumes that there are no other charging electronics embedded on the battery pack.
