ebike not works with fully charged battery

hello to the ebike community
my ebike is a new g650 lankeleisi
once assembled i checked the battery seemed like drained couldnt open the display , so i charged for some time then inserted it in the bike and made a test and all worked good, after 6-7 hours until the green indicator showed up in charger the battery was full with 54.6v . i insetred the battery but the bike wouldnt start, after somedays the voltage droped to 54.0 when i count in the voltometer, tried the bike and it worked fine , i contact to the manufacture and said was because of the poor contact of discharge plate and send me a new discharge board, as dicharge board showed me the part metalic plates that connect the battery once the bike folds. Does all that make sense? can i expect that is probably something else than this?

he is probably correct, if it happens agan just disconnect then slowly reconnect the battery, if the problem goes away you know its one of the connection pins! Post here if it happens again.

So,
I have a EBIKE kit, 48v 1000w and trying to for 1 thing to extend my range and the speed I traveled as sure ya know, the faster ya go, the shorter distance able to reach.

So,
I recently learned of and bought a 48v DC PMA ( permanent magnet alternator ) and dreamed how wonderful it could be...

At 1st was dreaming of running my bike off the PMA w no batteries.
Then woke up a bit and determined that if could just keep my batt.s charged better , enabling greater range and better speeds I would be so happy...

I am now seeing it's not so easy !
So to not overcharge my batt.s , I got a charge controller and relay that are set to 55v low and 57.6v high.
I just got batt.s fully charged and I tested this morning going about 17 mph only to find I wasn't able to get as far as usual !
So charged batt s again and un hooked the controller & relay running PMA directly to batt.s .....as while riding I watched my voltage meter and noticed I didn't go fast enough to produce but about 48 - 50 volts ...so trying to do better I only went about 12 mph on way back,. Did make it home and still had some power left...

Not sure if ya know of these pma yet, I sure hope so..
I was wondering of relay wiring, passive or active, rather running the hot or neg. From pma to the relay,
My pma is a super core DC 2 terminal unit at 1800 amps max. And when used and has a load, the pma becomes harder to turn.

So, I am guessing my 1000w bike uses more power than can be made going the speeds I'm able to travel. Guessing. 🥴

If you have any suggestions or referrals I'm so greatful !
And today I thought of a diff. Way that may work better.
Instead of trying to reach power needed to charge my batt s with the pma,
Why not only worry of producing 12 strong volts, hook up a 12v inverter and run the household charger used each day..?

Guessing that prob. Won't work for reasons not considered...?

Again I Thank You !

You sound very educated and maybe able to help me which might possibly help yourself , helping me 😋

Hi Shaun, what you want is impossible. You cannot run a PMA off your bicycle wheels and generate more power than was needed to keep the bike moving. If the world worked like that, maybe we humans wouldn't have destroyed it with climate change.

Hook the PMA to a propellor instead and when the wind is blowing. you can charge the batteries connected to your solar panels.

i just figured it out... the only answer to solve my problem is to have 2 batteries, one to power the bike and the other to be charged during..
then switch them ... over and over... what ya think of this wonderful solution my mind proposes...? just finding a answer that solves my issue when there is no other seams so good to me.. lolol

lol, i know nothing about batteries but if you start a separate thread on this topic there are plenty of guys here who are knowledgeable on the subject and they will chime in and help you. My thinking would be if you drain battery one and switch to the full battery two then put battery one on the PMA do you think the PMA will provide any type of significant charge before you burn through battery two? I dont believe it will but again i really know nothing about batteries.
