I have new cells to test/charge The EBC A40L tester works great but Id like to speed things up on the charge side to free up the tester. I also have a switching power supply that is 0-8v and can do 30-40 amps but has to be in the upper volt range to get the amps. Can I use this to charge the cells as long as there monitored to not go above a certain voltage say 3.45v or would this not be a good thing and just wait till all tresting is done then charge them up as one big 3v battery at 40 amps using the EBC or a 60v 5 amp bench power supply
