So I have a question so I have a relatively large 12 volt system currently on FLA golf cart batteries
And I'm seriously considering going to LIFEPO4 but one of my biggest Hang-Ups is that I have a 3000 watt inverter.. and while I rarely go above 2,000 w it would be nice to have the capability for things like starting an air compressor or kicking a motor over
It seems like as long as you stay 200 amps or less on the BMS it's reasonably affordable but the second you step up to anything above 200 amps the price steps up pretty quickly
Now I know one option would be simply to build something in the hundred to 200 amp range and then add another battery Bank a little later
One person even suggested leaving my existing fla battery Bank in place to handle those relatively short but High amp draw loads... Well this is intriguing it seems like it would require some electrical wizardry and quite frankly I'm lazy these days
But then I read about the option of installing your high amp draw directly to Lifepo4 battery Bank and then everything else would be installed after the BMS this still allow the affordable BMS to handle charging and balancing... While still allowing significantly higher current draws
This seems like a workable option however I would think that you would still have a strong possibility of over discharging one or multiple cells especially if they weren't particularly well matched...
So I don't know
