I'd get the 20ah one. Not only is it guaranteed to do your journey, but it'll get an easier time doing it, so it'll last longer. Plus, you might want to use your bike to go a lot further.

A think a could have problems with there battery as the battery plate only has to holes not 4 and me bottle holes on the frame quite low down ??

Nothing that can't be solved with a drill or if not brave enough an adaptor plate.

A can’t seem to work if it would just screw the new bracket from Greenlance , why have there change them to 2 slots instead 3or 4 ??

 

[Sparksandbangs]

The 2 slots on the greenlance holder can fit mounts between 5 and 8 cm apart.

The holder has an enclosure for a controller at the bottom and the underneath is metal. You can drill through that to get a lower mount if you are not having an integrated controller. I might be able to take a photograph later if no one else can point to one.

Would be helpful, thank you , and know a don’t use controller use TSDZ8 mid drive

Heavy batteries need at least three fixings, and you might as well do 4 while you have your tools out. It's not difficult to add a couple more rivnuts. All you do is:

• Mark the centre of the two empty slots
• Remove the mounting plate
• Centre punch the two marks
• Drill the holes to suit the rivnuts in several stages going up in drill size
• Insert the rivnut and crimp it
• Check that the screw goes in easy. If not clean the thread very carefully with a tap. The worst thing is if the rivnut starts to spin before fully tightened, as you cannot remove anything stuck in it.
• Screw down the mounting plate very tight to fully form the crimp.

You can get a rivnut kit on Ebay for not much. The biggest problem is getting your drill at the rightangle to drill the hole. It doesn't matter if you're not quite straight. You might want to think about using one of those angled drill adapters.

What one did you get , and roughy how many full charge you done is well over 100 and has the battery lost some off the range ,
