Lithium batteries

[Kooter]

Looking to get new batteries for electric trolling motor 36 volt. Need three batteries. What’s the best bang for my buck on batteries hoping for some help. Thx

Costco, can't beat the price, 130$ for 27DC, bought one yesterday

Edit: Oops i didn’t read lithium sorry! For these i would honestly just take cheap off of Amazon, coming from same factory as expensive brands from China.
They are roughly 500-600$ CAD for 100ah atm.

I got mine from Canbat. Two 75ah ones, came in like 2 days. It's great not having so much weight up front, and I can discharge them down pretty much all the way, unlike the one lead acid ones.
