I only know basic electronics but if like to build a basic 20 amp transformer lead acid battery charger from reclaimed parts, they are not cheap to buy but consist of not a lot inside, a transformer, a rectifier and a tiny PCB, I can source all the parts but can I buy the PCB off the shelf?
Can I rewind a commonly found transformer like in a microwave oven to 14v?
Can I use multiple transformers to get a 20 amp output ?
