somewhereinusa Posted August 13, 2019 Report Share Posted August 13, 2019 I'm upgrading my house bank from 4, 6V lead acid golf cart to 4, 12V lithium batteries in parallel . My inverter has a max charge rate of 150 amps and each battery has a max continuous discharge rate of 150A. According to the various cable size charts I have looked at 4 gauge is good for 200A at 4 ft with 2% loss. My cables will be less that 2 ft. I can get a really good deal on some 4 gauge wire. Does that wire size sound right with a safety margin? __________________ Quote Link to comment Share on other sites More sharing options...
