This is my first build and I'm pretty much set on the kit I want (Grin MXUS 3006 with the 25A Grinfineon controller).
I intend to buy my battery from EM3ev. I hesitate between two packs but I'm open to other advice. I'd prefer either a bottle mount or a triangle. Bottle mount sounds more interesting to me, although I realize if the mounting plate is not well built, it can be a problem. EM3ev's seem to be metal reinforced.
My two choices are based on my assumption that I should have a pack that provides continuous current at least equal to that if the controller (I have some slack since I will be able to limit it with the Cycle Analyst).
Candidate 1:
Bottle mount: https://em3ev.com/shop/preditor-l-47v-8-4ah-11-8ah-frame-battery
46.8V 11.8Ah 35/40A 13S4P "30Q" cells
Candidate 2:
Triangle: https://em3ev.com/shop/50v-14s6p-small-triangle-pack
50.4V 17.1Ah 34/51A 14S6P "PF" cells
They are both similar in price, but the bottle mount has almost 50% less capacity. so I suppose the 30Q cells are better quality.
My requirements for range are somewhat flexible. They're not that high. I'd need only about 10 km on my normal daily commute, and I (intend to) pedal. But I'd like to have maybe up to 50 km for longer trips.
The 30Q in Triangle is substantially more expensive and the specs of the PF (triangle) look fine to me. But what about the 2C rating? I'm wondering but they don't even give the C-ratings for the bottle mount packs.
I think otherwise my ideal candidate would be a bottle mount (if the case quality is there) with 48V at about 14Ah.
What's your general take on all this?
Thanks in advance for your input!
