A level of care and attention to the condition of the battery as well as a charger capable of monitoring and charging at these rates is necessary. I wasn’t a believer until I stepped up from 20 amps to 40 and started discharging. They also discharge at 40 but I’ve found 30 still gets the IR’s down for a punch that doesn’t fade for an entire race.
