Charging with a automotive charger
Has anyone used an automotive charger for charging their off grid system? I have been using the charger from my Xantrex Freedom 458 for 10 years now ( is 16 years old) and just smoked last week. I have it in MAYBE getting fixed (Mexico) so bought a Schumacher SC-1353 portable charger for temp use. I only need to use charger a couple times a month. It has 200 amo engine start, 40 amp boost and 6 amp normal charge. I thought I would ask their tech support about charging batteries in boost mode. The GUY told me boost would shut off in 10 minutes. I thought ohhh, it seems like a heavy battery charger to only use 6 amps. So had it charging yesterday morning, 8 - 6 volt golf carts, and yes it is 12 volts, and yes I know people don't like 4 parallel strings. Well it went to boost mode and stayed there for 1 hour untill I shut it off (solid 37 amps] . Wires were warm not hot , and unit wasn't very hot, and it's 90 f here. Any thoughts about problems using the charger in only boost mode.
