Looking for 12v AC-DC battery charger recommendation.
I'm looking for an AC-powered DC battery charger for supplementing my battery array on cloudy days. I am not looking for an inverter charger, or anything that starts a generator. I have smart and dumb chargers but all the smart chargers I can find are tailored for maintenance free automotive batteries, not an array of golf cart batteries under load.
Basically what I'm looking for is a charger with thresholds I can set. Like it doesn't do anything unless the battery voltage drops to 11 volts and then it kicks on and begins charging until it reaches 13v and then goes back to sleep until/if it's services are required again. Or whatever voltages I set. Because the solar chargers are doing the heavy lifting and just need help every now and then when the clouds roll in.
This seems like a no-brainer product that should be easy to find but I haven't been able to find it, just a bunch of DIY "workarounds". If anybody can make a recommendation I look forward to reading it. Thanks.
