I can charge them a 30 amps max, I'd like to charge them at 40 amps which is 2c.
To get the full 1344 watts (40 amps) I'd need 1344 watts plus 20%.
Thanks, Angelo

The Powerlab8 wattage rating of 1344 is based on 8s. For a 6s pack the max wattage is 1008 at 40 amps. Add in charger efficiency of 90% and you need 1120 watts to max out the PL8 charing 6s@40 amps. The 47a supplies are good for 575 watts, each and I know if one person that has successully pushed it past that (but for how long,?????). So two 47a supplies will give you 1150 watts. Also remember that the wattage peaks occur near the end of the charge and don't last all that long. The charge will start at about 90% of peak wattage and granually increase as the cells reach 4.2v.
