New battery

[bigfootpete]

Something else I have noticed about the battery yu bought, LiFePho4 has way more energy capacity in the same phyiscal space as a LeadAcid, so I think your getting short changed. That battery should be more than the 14Ah, at a guess something like 20Ah -

And while going through the list of Yt vids from the link I posted above I found one saying what I have been saying, you can not drop a LiFePho4 battery into a bike with a charging circuit design for LeadAcid -

Thanks for the links, I'll do a bit more research to see what I can find out.
You'd think the website selling these would have more info rather than just lumping these in with all the other lead acid ones saying it's a direct replacement.
