New battery

[Dudeofrude]

Personally my biggest concern with lithium batteries is their tendency to explode when pierced, not a great thing to have in something as delicate as a motorbike in my opinion. It's the same problem all these fancy new electric cars are going to have, catch them wrong in an accident and it's gonna look like a Hollywood car crash.
I know the chances any kind hitting them under your seat it quite minimal but it's still a risk
