Question:

hi, i have qty 4 renogy core series 200ah 12v lifepo4 batteries, in parallel for 12v 800ah system. I need a chargers that will charge these batteries quickly each battery can charge at 100A at 14.4vdc. the chargers i have right now. both taper the current drastically charging at 15A right now at 58 SOC after half a day on my 120A ac to dc charger. I need to charge quickly, high amps since Im running my generator. Will this charger put out 14.4v at its rated 80A without current limiting? If so, is there a charger that is rated 400A or would i need to buy 5 80A chargers? thanks and sorry for my ignorance

The highest rated charger we have would be the Go Power Pure Sine Wave Inverter Charger part # 34280055 which is rated for up to 100 amps and is lithium battery compatible. Running this to all 4 of your batteries would put a 25 amp charge on all of them if you charged them in parallel. Or if you had the power available you could run multiples of this charger to your bank.
