How to replace original battries

We bought this moped in 2016 and unfortunately we did not kept the batteries fully charged all the time. This seems to have lead to broken batteries.
I decided to replace them all.

I got in touch with the reseller of the moped and was told that they have a better replacement battery type than the battery type that was installed originally. I bought six new lid replacement batteries, pretty expensive ones. I could also have bought six new lithium batteries but they were even more expensive.


Unfortunately, the replacement batteries are bigger than the original batteries so I had to "rebuild" the moped a bit, after instructions from the reseller. Originally all six batteries are placed under the backseat. But now I need to put four under the backseat and two under the driver seat.




This is how I replaced them. I first removed the original batteries and the removed the driver seat.

Build a supporting floor under the driver seat.




I also put some rubber carpet for vibrations.


The batteries is placed on the new supporting floor.


It is pretty tight


To lift them up I needed to do like this, it might help if you got a friend that can help you.




Make sure the batteries are firmly tightened.



Under the back seat, I put the rest. I filled the gap with some material that I had.




Before mounting the last two on top I build a tree frame.


I finally connected all of them. I experienced an electric flash when I connected the circuit, so be very careful.


This is how I connected all of them.
