The bike is in used but good condition except for the battery...
Its a single 36V 8Ah lead acid battery (WP8-36E)
I managed to get it revived somewhat by refilling with 5.2 % acid battery fluid and charging it first with a higher voltage (~56V).
However instead of 36 I get 32 V stable discharge voltage :(
That means there is more than one short cell...
I am considering to hook up some extra cells to get the electronic to work with the current cells.
For the short term and to test it all out I hooked up simple direct switch...
I find that the top speed is not satisfactory for me, I can pedal much faster on my regular bike!
So I am wondering If I find some replacement batteries and make a new electronic control board, how fast can I get that Heinzmann motor to push the bike? Any experience reports?

I like these type of batteries a lot, just would like them to be a bit less costly:

I really like to think of this ebike as my personal precursor to an electric motorcycle...
I find these quite impressive:

Thanks for any hints!
