You cannot charge lead acid that fast. That is the problem. Look at the charge algorithm for bulk, absorb and float for those batteries. That is the big advantage of lithium batteries, they’ll take 100 amps. But, lead acids charge more in the 10\15 amp per hour range. You will shorten the life significantly doing it faster. https://www.upsbatterycenter.com/blo...20expiration).
