Hi; did you check the bmv manual? It explains how this works. The conclusion is that the cycle counter is not reliable to see age of the battery.


Cumulative Ah drawn is a much better gauge.

If thats the case then its not working correctly, as per page 29 of the manual.


I have taken my batteries down to 20% now 3 times and back up to 100% and the cycle count is still displaying 1


I am refuring to the mobile app display


also is it posable to drop the 65% figure to 20 or 30% as the 65% figure is not really applicable for these batteries, (if it worked that is

No; sorry. Hence the recommendation to use the Cum. ah drawn instead.

Thats strange; is the unit on VRM so we can see the cycle and all the data?

We re-tested this quite recently; and conclusion was that it works ad advertised (though has limited value).
