This is how I’m planning on doing it for now. BMS inside the case and ESCs directly on the water-cooling loop. The phase wires would go out where those fittings are so if I wanted to add water cooled motors it would be set up for it.
Not sure on the temptation myself - they’re 2c discharge recommendation, not sure what the actual continuous discharge is going to be and because of that its hard to really be interested other than the price.
BHU is sometimes a bit conservative with their ratings. I think they are rated for 15A continuous, and they certainly can endure higher peaks and some good charge rates, after all, they are used in a well-performing EV.
I dont think there are any official numbers on these cells are there? BHU always posts conservative numbers and thus far the testing I’ve seen out there has been pretty casual. I haven’t seen anybody reputable really put them through their paces with accurate equipment yet, although if you have, I’d love a link?
I agree, and we can infer some numbers by comparison to similar 21700 cells, these are gonna be somewhere between 40T and 50Es, but the Tesla cells historically have been a bit better on pushing amps for their capacity.
15-20A continuous sounds about right to me, and 25-30A burst seems easy. Should be a highly economical middle ground between the 40T/p42a for more cap in less amp hungry builds… I’d think these would be killer for range on street boards.
That’s my problem - no information out there on if these cells will perform well at 15amp as its all assumption, which means by the time we (specifically I) get any details, these will likely be long gone. I primarily want these for my current build which is a mountain board. If I had a street only board i’d not concerned.
But silver lining if I cant be convinced it means there’s 100-300 more cells out there for one of you guys.
I get that for sure. Personally I’d be hard pressed to look at anything other than 40T or p42a’s for the build you describe. I’m going with p42’s for mine, $4.7 each is pretty hard to beat.
Ahh the advantages of living in a society that’s progressively rejecting the expectations of personal responsibility… It’s a beautiful world! Amiright?
I guess I’m wondering, are these companies making their own estimates for these cells and printing their own different wraps for them? Or what’s happening here?
