Needs work

I plugged it to my Porsche lithium battery for maintenance. The battery was ok. It started saying the the voltage was at 13.5 and needed 8 hours for a full charge. One light fully lit and one light blinking. After 5 hours the state was the same, 8 hours to fully charge. The voltage was at 13.8. Then suddenly, in 30m it went to fully charged. So it took 5.5 hours, but how can I trust these numbers if it tells me that it still needs 8 hrs of charging, and 30m later it’s fully charged? Also, it’s supposed to identify my type o battery but it doesn’t show this anywhere. How do I know that it recognized my battery?

Good

Good product, good app. Lack of polish language is a little minus.

История зарядки

А где обещанная история зарядки для CS one gen1 ? Заряд на паузу тоже не поставить ?

Charger display does not reflect app

Charger unit continues to flash start whilst app shows 3 bars and 4 hours to charge complete. Garbage.
