Powabyke Euro Polarity

[sheryck]

POWABYKE EURO POLARITY - Hi All, just acquired a winter project of a PB Euro without battery or battery box; I can overcome this but currently not having a box to copy from I don't know which spring loaded terminal, when sat on the bike looking down at the controller, is the 36v +positive? I am guessing the right-hand one - can anyone confirm please?

I have copied and attached for clarity, with thanks to PB, two pictures from manuals from the PB website and marked them with MY GUESS + & -. This guess is based on bad memory and red paint on one of the screws in one of the pictures!

Many thanks in anticipation and a Merry Christmas and a Happy New Year to all

Hi

Open up the cover and check inside if you get it wrong you will damage the controller

also there is a battery case on Ebay only 3 hours to go

I can also recommend these battery's from Rita

I agree with Frank. Remove the cover and you'l see the colour of the wires: Hopefully red and black.

Simpler to just put a multimeter on it - if you put the minus and plus leads from the multimeter to the wrong terminals on the battery you'll see a minus on the multimeter display - i.e -36v. If there isn't a minus on the display then you have the plus lead on the multimeter going to the plus terminal on the battery.

Makes sense?

Think you didn't read the bit about there not being a battery?!?!

Thanks Frank - and for the links. The eBay case is for the Shopper I think, not the Euro. Reference the batteries I was thinking of something lighter and smaller for this project (the original apparently slipped from wet hands at the top of concrete steps - hence it being non-existent now) something I can understand having previously dealt with 3 x SLA. I can always make a suitable case if it comes to it, or use an original Euro as PB did when they first used Lithiums.

Thanks for your comment.

Thanks John, I had previously looked at these and was left unconvinced as to the polarity of the sprung terminals on the bike. You are highlighting the dismantling procedure as suggested earlier? or maybe I am missing something?

 

[sheryck]

No I didn't

No worries - we all do it - thank goodness for e-mail recall!!

I have 2 powabykes and will check to find the positive connection for you

Hi John, Happy New Year. Any progress with locating the positive?

 

[johnc461165]

Happy new year to you sorry about the delay, just checked my battery and as you guessed the right hand contact as you are sat on the bike is the .......POSITIVE CONTACT. thought I would shout it at you. good luck with your project. John
