I highlighted this on the OpenInverter and DIY EC forums (linked).

In short, $12.50 for contactors worth hundreds each.

And for the 1000 posts a year we get for people hoping to build a cheap EV, I highlighted two pretty much dirt cheap battery options that’ll get you 90 miles for ~$1200 + shipping. Both on new/uncycled/barely cycled cells.

They’re heavy for what they are (how many of you can afford to add 600lbs?) but all things being a compromise, there you get cheap.

Maybe most of you would have to squeeze by with a 45 or 60 mile pack because you can’t fit the size or weight in your vehicle. Oh well, still the cheapest way to get yourself rolling on an EV. Beggars and choosers.

I’ve no affiliation with BatteryHookup other than being an occasional and generally satisfied customer. Not getting a kickback. They don’t know I’m posting this. No shenanigans.
