As per title, this has obviously been discussed a lot over the years, but what are current suggestions for trustworthy high-power batteries, ready to plug and play? Not too concerned about form factor, I can work with most things as it is for a large cargo bike. I've had only positive experiences with Grin and EM3EV, but shipping is a killer from Grin sadly and EM3EV don't seem to have anything in a 21700 cell type at this stage. I'm wondering if any decent new players have emerged.
