Yea, it’s going to take a while before these come down in price…maybe a long, long while.
Basically, for any cells we buy we have to wait until there is excess inventory at one or more of the big customers for these cells. It gets sold off and eventually makes its way to a distributor or cell rewrapper who sells to vendors who sell to the various communities (esk8, vaping, flashlight, etc.). There is an occasional unauthorized direct sale by an unscrupulous sales rep at one of big manufacturers but this doesn’t happen often.
I ride fairly aggressively but have only pulled 40A max out of 12s/170-190kv builds. (That was on a full battery accelerating up a very steep hill.) Between 2:1 and 4.4:1 ratios. All 3 are geared primarily for torque.
Granted I am on the lighter side, so that might impact things?
For context, I’m thinking of a 18 or 20s HV build with low KV and 7-8” wheels. Ratio of around 5.2:1 to 3.25:1 Do you think something of this sort would pull more than 20A/cell?
(I’ve already plugged lots of different numbers into the calculators and they don’t seem to suggest a high current draw, likely due to the HV nature.)
100%. Battery current on a board is proportional to total power draw, and weight plays a big role.
I think if you’ve only pulled 40A battery from 12s builds, then your high voltage build (assuming it’s at least 2P) will pull even less, so yeah, seems like the Samsung 50S is the cell of choice for you, assuming it’s cheaper than the P45B
I think the esc is pulling 50A total, so 25A per P group. Kinda puts you right in the middle. Mooch can give you a better reccomendation, but I’d say if your riding it hard most of the time, 42a might be slightly better. For mixed riding 50s.
Typical, I’d go with 42A for 25A per p group requirement.
50s for 20A.
Overall I don’t think you can go wrong either way.
