I have a cell module that contains six volts and 50mA. I was wondering if it could be possible to make it charge batteries. I have it hooked up to some potable speakers but it only manages to allow the speaker to run at half the power. I am looking for something that can hold solar power so that speakers can work at full capacity. I have some rechargeable triple A batteries but I am not sure if I can just wire those up to the solar module and it will charge it. How can I make solar power cell module charge? I would really appreciate your useful information. Thanks.
