hey my fellow diy'ers..
i've just bought a handful of CC/CV adjustable boost converters in order to charge a bunch of 40v batts for resale. I'm in the middle of testing one out before "deploying" them all and i'm watching the volt/amp meter and the current is basically staying steady even as the voltage is raising!?!?
on all my other cc/cv power supply's the current decreases as the voltage rises.... so far on this one, the battery has increased by 6v but the current is still holding at 2.85a. it actually has increased. i had it set at 2.79-2.80
should I be worried? or just keep and eye on it and see if it starts to fall as the battery is getting almost full?
i dont believe there is any other way of setting the parameters for CC/CV.... and i assume they are all "supposed" to work the same correct?
thx
PS. I just turned the voltage setting down and the voltage does drop quickly as it approaches full voltage so i think its ok.... just my other cc/cv supply's seem to start dropping current much sooner

*** IF YOU ARE NEW TO LITHIUM ION BATTERIES AND CHARGING THEM, IF THEY HAVE MULTIPLE CELLS IN SERIES (IE. THE BATTERY IS OVER 4 VOLTS) YOU SHOULD USE A CHARGER OR BMS WITH A BALANCING FEATURE!!! ALSO YOU SHOULD CHARGE AT A "1C" CHARGE RATE TO BE SAFE OR NO HIGHER THEN FACTORY CHARGE SPECIFICATION !!!
AND
*** IF WHILE CHARGING, YOU FEEL THE BATTERY GETTING WARM AT ALL THEN STOP!!! EITHER YOU ARE CHARGING WITH TOO MUCH CURRENT/AMPS OR THE BATTERY IS DEFECTIVE!!! BE SAFE
