I purchased this vc8 on 3/15/2020. when running the capacity test recently it will only read 5-150mah alternating with FULL with a voltage of just over 4-nnever dropping below 4. this happens on old and new 18650 cells. all 8 slots charge normally. is there a solution? if not who do I contact for warranty?
Which slot are you using? Did you select the Grade mode?
seems I hadn't selected grad mode, currently only slots 1-4 can perform the capacity test, is this normal?
Yes, that’s normal.
