I bought the LIPro Balance Charger Imax (LIP-CR-IMAX-B5) from cytron.
but when i try to charge 11.1 V LiPo Rechargeable Battery (LIP-11.1-1500) using this charger there was an error msg 'IN VOLTAGE ERR - ' . I try changing the ac-dc power adapter supply to several different model but still the error persist. When I measure the voltage from the ac-dc power adapter before charging start the voltage was constant about 17V but when charging start it drop to 9V. This happen to all of the ac-dc adapter that I've tried on. Is there a special power adapter that I need to use or is there any solution for this? please help.
btw:
I've tried both Lipo charge program and Lipo balance charge program available on the Imax B5 charger. the result is the same.
