Hello,
I already posted this in another thread, but I have realised it was buried in someone else's welcome thread, so it might not get seen by too many.
New here, so hello everybody! I have had my Kalkhoff since new, using it sporadically (sometimes intensely, sometimes hardly at all, depending on need), so it has had a total of about 7000 km over the last five and a half years.
I just splashed out on a new BMZ 24Ah battery for my trusty 2010 Kalkhoff pro connect S.
I have had it for a week, so I am still running it in and calibrating it as per instructions (three times full charge to discharge)
On HIGH power I am getting about 55 km on it before it drops to the single flashing light and ECONOMY kicks in for another 15 km or so. Does that sound about right?
Also, when I am down to two out of five of the levels, for some reason, if the lights are on, the battery level drops to zero sporadically and I get no power at all until I turn the unit off and restart it (coasting along to avoid an error code being thrown). This happens irrespective of the power setting (except when there is no assist at all). The controller is still on, the lights remain on, and the power indicator still show HIGH - it is just that the battery level indicator has suddenly lost all of its remaining levels from the two that were showing. Any ideas? If the lights are off, then I can continue without this occurring. Could it be something to do with a faulty battery management system - the lights drawing too many amps and causing the battery to think it is dead and needs to switch off? Or could the fault lie with the controller... However, my old 10 Ah battery is still OK (it shows 4 out of 5 when I hold the battery button down) and it never has this battery-level-down-to-zero problem. (I bought the new one because I can only get 20 km out of it on full power so can't manage a full two-way trip with my current cycling demands)
Thanks for any input.
Mortimer
