I’ve just built a 10S9P pack with NCR18650GA cells for my Trampa with dual 6374s which has been built to climb big off road dirt tracks. I’ve only given the board a few quick test runs at this point but its handling things really well so far.
Going 9P with these cells when you’re not even really planning on going off road should be a non issue.
Not sure what chemistry Samsung’s 30Q uses exactly but I believe these Sanyo cells are essentially the same chemistry that Tesla use (LiNiCoAlO2) so I’m expecting to get a decent amount of cycles out of them.
Looking to do some more serious off road hill climb testing this weekend so will be interesting to see how things go.
I also have them in 10S3P, climb lots of hills with ease, dual 5055, I can climb 17% at 30km/h
The limit speed for climbing higher inclines is 17km/h due the duty cycle ratio between battery and motor current, in that condition I tried a max of 22% so far
They should be great in big P config, there’s a point that there is not reason to have more discharge since you prabably never use it
Also worth mentioning that Mooch’s tests are done with these cells pushing 10A for the entire time till they’re completely discharged, something that never happens for our use case.
At 9P, chances of using anywhere close to 90A for more than a few seconds at a time seem pretty minimal unless you’re doing some crazy hill climbing
I’ve read like every 10th time its actually good to fully charge and discharge (not below 31V).
@moon I’ve only got about 2.5 months on that pack. So time will tell.
Perfectly fine, I’m nearly 300km on them, same performance as the first time I tested, managing do ride 36 km with a 33 km/h or 44 km if I limit the board to 25 km/h
But… the more I ride the more I want more in certain situations, like hills that I have to keep up with traffic, other than that it’s perfect for me, I’d rather loose a bit of climbing and be able to run 44+ km than climb one or two hills more quickly and have less range
Yep, this is my run with the 25 Km/h speed limit, was adjusting to the new deck when I did and the confidence was low, if I have time i will do this same route again with the higher limit, the 36 Km is based on the consumption I’m getting, 10,3 Wh/Km
Riding style changes the range a bit for me, but not too much, if I’m just riding near my house I ride more aggressively, but at long rides is almost constant speed and a hill and another, there’s not too places I can ride here, smallish city and I guess half of the streets are bad pavement to ride
I made a new mode limiting the currents and speed a lot, let’s see if I can crack 50 Km
