I want to build a Lead acid battery charger. for that I want to use a small IC engine coupled to a dynamo and the dynamo I got is rated at 12V, 35A and I want to charge 12V 7.5 Ah Lead Acid battery. so here are the doubts which arose.
- Can I connect the dynamo output directly to the battery(with blocking diode of course) and expect it to charge since the battery's full charge voltage is around 14 V and dynamo is rated for 12V.
- And why is there such rating on dynamo, will it not produce more than 12V if it goes faster??
- Will I need some sort of current control while charging the battery or the battery will draw required current.?
- I just want a brute method which just works, I don't want to go for full charging algorithm stuff.
