New XP 3.0 folding step through - power bleed w/ switch off ?

[Santa]

I havebought (2) new XP 3.0 folder/ step throughs. I only have one set up ( correct dimensions, new bars. etc for my wife). I rode it about 1/2 block down to see if all works . My question. With the battery switched off. I note you can push the power button on handlebar and display will light up momentarily, then go off. Then you can repete, etc. This can/ will happens after sitting 1-2 days, nothing else happens. Is this normal ? I have yet to contact Lectric on this and may not be anything. To me an off switch turned off means- OFF ! I powered the bike up and checked the power ( energy bar) shows battery is still full. I suppose as soon as I get mine ( the second bike) set up I’ll find out it’s it the same or not. At any rate, anyone else notice this taking place ?. Lectric has a high volume of calls each day, soI haven’t tried my luck yet. Thanks for any responses.

I always leave my key turned ON when the battery is in the XP 3.0. The few times I've actually turned it OFF at the key with the battery installed in the ebike the dash will, briefly, turn on. I think it's just residual power or something. Doesn't matter for how long it's been turned off at the key for either.

You'll also get used to the voltage sag. I can come home with 4 bars left and it will easily double the battery bars the following morning. Again, normal.

Thanks sc00ter. I’m getting there. BTW, I’m still experimenting w/ bars for my wife’s bike. I turned the existing neck around 180 deg, and added some moustasche bars. Getting closer. I have some other bars coming that will work w/ the shorty I got from you. My wife insists the st up is identical to her Townie Electra. I had to make parts to move the seat back to mimic the layout the Townie has ( pedals 7” ahead of the seat stem) . I previously measured everything on her Townie, getting there.

Capacitors on the electronic boards and power supply control circuits hold a charge kinda like a battery even though the power is disconnected (or battery key switched to the off position). Capacitors work different from batteries though and will discharge all at once so when you push the power button the capacitors provide a moment of power to the circuits including the display causing it to flash on. It is normal and not anything to be concerned with, it does not provide any power to the motor. It will only occur once after battery is on and connected, then turned off then power button pushed as the entire charge of the capacitors is used up all at once.

Thanks, your right. I forget about capacitors holding a charge for some time. Didn’t think about them in all the P/C boards and circuitry, but I guess it’s necessary for anything/ everything made in the electronic components to work right .
