Valid points, but the price difference is substantial. Bumblebee wants $2095, I think plus 2x shipping to Oregon (2x because you have to ship your old battery to them). Yabo wants $1500 (on AliExpress) or $1214 (
quoted to Martin "mauimart" in September),
including shipping,
and you get to keep your old sticks (which have some resale value).
I wonder what Yabo is doing about the PTC thermistor strips?
I also wonder how much they really matter. Do other HEVs have them in their batteries?
