[QUOTE="WTM, post: 5680995, member: 6230"] lead acid batteries cant take a high amp fast charge. itll kill the lifecycle of the battery. 20% of C max, especially for deep cycle and charging at a higher rate is counter productive with the higher resistance of the thicker plates. itll get to a point to where it will quit taking a charge until the charge current is lowered. cranking batteries can take a wee bit more but most manufacturers limit to 20 amps at max which is considered a fast charge, except for specialty batteries. lithiums are right opposite and most BMS' can handle a full 1C charge.
