^^ Yeah, I just lived without the starter for a while until I found a good sale on a Shorai. Got it from Vancouver, IIRC. Wasn’t that expensive in the end.
Edit: I was curious, so went back and checked my receipts. The replacement stock battery (Yuasa lead acid) I first bought was only $45, so crazy cheap (and even free shipping!)
I don't have the receipt for the Lithium, but I bought it from baysideperformance.ca. I got the biggest one that would fit, which is currently selling there for $184. I can't remember exactly, but I think I paid around $160. There are smaller Shorais that would have fit and are cheaper, but I wanted as much juice as I could get. And there are probably other brands that are cheaper, but Shorai seemed like the preferred option.
