Do trampa superstar and mbs rockstar II hubs have the same mounting pattern? I see they are both 5 spoke, but I cannot find anything on the exact spacing between mount points. Thanks

Hi, it depends if you want to be able to carry the board, like into a store or whatever. If youâre going to actually use it for transportation you may want to go for the lighter battery.
If itâs being built for a toy, then maybe the bigger battery.
I get about 32Wh/ mile with high speeds (40-50km/h and lots of off road. Itâs more like 20- 25Wh/mile with moderate speed and road only. My pack is a 12s4p 30q so its an easy 10 miles with lots of reserve worst case.
Hi, i lookinâ for a new lipo pack after killed the old, for my emtb (offroad use), i would have 80amps continue on each motor (vesc6+8085aps) on 12s setup
this
or this
why no one use this 6s 20Ah ? some reason ?
If you want 80A continuous then those â15Câ and â12Câ packs arenât going to work well.
Try to find a â50Câ or â80Câ pack
C means âper hourâ so for example 20Ah times 12C equals 240A
The only problem is that manufacturers severely exaggerate these numbers as a marketing gimmick. You can probably divide by 5.25 to get âactual usabilityâ numbers, so that would mean 22.8A per motor on that pack
If you bought ten of those 6S 12C packs and connected them 5P for a total of 12S5P then youâd have a 12S 100000mAh pack that can do 228A, but itâd cost way too much and be way too heavy
ok, i forgot 80A continuous, i only try to find a power pack who can drive correctly my motors and vesc6, thanks for explanation
Is there a bms where u donât have to connect wires to the batteries ⌠well where itâs essentially plug n play?
anyone know of a bluetooth pairing code for the unity?
no bms, and i gave up li-on because of the crazy cost (charger, cells, bms) and the place it takes.
i have a lipo charger who work well, and itâs easy for me to charge 2x6s with 2 wire plug than 2x4x whatever cells in serie/paralel (is the word exist?)
no pairing required, connect thru the app!
So BMS are for wussies? And I can just hook up a charger to the batteries?
Yah big lipos are just hard to mount unless you are just plopping them on your deck too clearance is an issue for some people. I used lipo for a few years still happy with that for my portable board but got a bigger Li-ion for a bigger cruiser for less hassle and more juice on the board with a slightly smaller brick.
BMS is for less hassle when charging imo but more risk of crap breaking on the board. Fancy BMS can do some telemetry about the cell health as well.
Phone asking for a pairing code
donât understand wussie, sorry.
I have a 208B charger (8s lipo balance/charge/discharge/storage etc) so, i dont need a bms
I only open the case, unplug the serie wire , plug balace and main port and charge at how many amps i need
Hey Stan, I take my bearings and clean them real good with isopropyl alcohol, let them dry, then coat them in PTFE dry lube, let them dry, then glop a couple good glops of white lithium grease in there and seal them up. They roll butter smooth from there and last forever. I used to use bones speed cream but it doesnât last nearly as long or roll as smooth.
@b264 @Andy87 Any good epoxy recommendation for battle hardening? My motors sometimes have a grindy sound. Not always and i canât always replicate it (Never while driving)
You can plug a charger directly to it. It will work.
However, this is a risk of the different p groups of becoming unbalanced. The charger will detect total voltage but not individual cells. So for example sake, you have a 3s3p (total: 12.6v charged)
You charge it to 12.6âŚbut:
p1=4.22v
P2=4.23v
P3=4.15v
Unbalanced cells will only get worse with every charge
Bms will help by bleeding overcharged cells and allow under charged ones to catch up
So is this the case with li ion where you connect a bms but not the balance wires or that only does that if you have the balance wires connected?
