We are having a lot of talk about simalar thing . This may be the same issue for some of them.
5 bars to zero . short charge or range . What I was told was you need to sink the bars / miles to go and the charging sequence . The change is not just by volt it is from a zero set in the software. and also as some of you know the type of battery Vectrix uses has a memory of sort. it need to know its zero.
I was told to run the bike out completely . If you run down close you will help the battery zero set. but not sink the display and charging software. Completly like it will not move at all . It resets by holding the trotle wide open for about ten sec. bike not moving.( I would do it longer after taking all the time to run it down) this is supose to sink the charging sequence and the bars / mile to go . Ya I know this is a pain to do. on level ground the Vectrix gose a long way . and as many have said you don't what to push the vectrix up hill.
Also doing a full charge or just what you have time for will not change the charge set point.
Ask your dealer they should have ben told this Too.
Happy riding , Herb
