Please I need a switchable 6V/12V Lead acid Battery Charger circuit?
I have an old Lead Acid charger that is 6V/12V Compatible but it has only 8amps current and a part of the label reads "suitable for up to 40ah battery" I have 6V/200ah batteries which I connect in series with a modified APC UPS (extended leads to external battery)
I need 6/12 so I can be able to charge a single battery if need arises.
I would like a 20amp charger so the batteries can charge faster. I was thinking the transformer can be used to achieve this. And also, I would like it to be current limiting (Current reduces as battery reaches full charge)
I would like it to have digital voltmeter and Ammeter displaying voltage and current used in charging the battery and maybe few LEDs to indicate FULL CHARGE.
Thanks
