For now, my board tops at 40km/h and I feel like it would be nice to go a little faster. But my main concern is that I am kinda heavy and live on a hill and I would rather not have to walk and tow my board 
Swapping batteries, unless youâre increasing the voltage, wonât help you achieve a faster top speed.
You should get a smaller pulley for your wheel, or get larger wheels
7.5ah will go SO QUICK at full tilt. I think thatâs part of boostedâs special formula. Low amp draw, high discharge cells.
I totally forgot about gearing lol, I will have larger wheels but I thought this meant going faster
I mean the battery is for a different board.
I think the 30t is the cream of the crop(for 21700, I want 32xxx to mature a little bit more 8) ). You basically get a123 levels of performance (if youâre living by moochâs rating. I do, personally.) With a full 3000mah battery.
(Again, imo) 40t is worse to the 30t due to increased thermals at the same amps, and the marginally larger amount of sag. I donât care about the increased range
Have I made it clear I seriously hate sag? ![]()
Sorry for all the edits Iâm just trying to be coherent o_O
Similar to any high discharge 18650. Too hot degrades the cells.
Cold performance is just okay, but much better than other cells.
I have 15s2p in a hummie with 2x focbox and a smart bms. Had to widen the cavity a bit.
Bottom Line: This is an extraordinary cell that I am rating at 30A. The two cells I received from EnerCig and the two from Nkon appear to have come from the same batch.
The datasheet has a âmaximum continuous dischargeâ rating of 70A in the datasheet. But at that temperature, about 85°C, the cell will have a significantly reduced cycle life. This rating is an absolute maximum, not a level you should operate the battery at for every cycle. To allow direct comparison against other batteries I am rating this cell at a level, 30A continuous, which limits the temperature to 60°C to ensure good cycle life. Above this temperature the cellâs aging accelerates significantly.
I have 3 boards with these cells. 12s2p 2x6355, 12s1p predatorboards esc+hubs, 15s2p hummie deck hummie motors. I remember @bigboytoys running 14s1p per motor (4wd). 1p per motor sounds about perfect.
The batteries have a bit strange behavior. They charge up to 3.6v/cell, but quickly drop to nominal 3.3v/cell and kind of stay there until empty. So you only get the âfull charge fast fastâ effect briefly, but they stay strong for the rest of the ride.
Range is what you expect from 2.5ah/cell. 12s1p is 99wh. 20wh/mile or so. They have low internal resistance, but not crazy low. They do sag, I think I have 4-6 volt swings during a ride. But they feel strong. I donât think Iâve managed to pull more than 70a battery total from my 2p packs.
Though mooch rated them continuous for just 30a, they can push a lot more for a few seconds at a time. Up to 120a.
The 12s2p was my first build, and gave me a huge margin of error for my n00b fuckups. Probably would have killed/damaged like 3 normal packs.
I really like these cells, but theyâre bulky, heavy, relatively low capacity, and relatively expensive (usually). Iâd put them in a 1st build and in a cold weather board.
Iâve posted often about these cells. Thereâs other crazy characteristics, like you can charge them to 4.2v without much ill effect, you can charge them at 20a or more (amazing for regen braking).
12s1p 99wh is perfect modules for air travel too, although diy packs⌠not really.
I said if I remember correctly! Im gonna take my âget out of jail free cardâ that comes along with the statement 
Thanks for the correction though 
@deucesdown arent you also in the choo choo group buy? Have you done any calculations as to how many of these would comfortably fit in the cutout?
If you havenât, I can just do it myself⌠I just figured I should ask lol
Hmmmm! But bigben single stack probably wonât deal with the height.
I want to do so much to modify that board, its battery cutout is just slightly too small in almost every direction for what I want from it ;_;
Some photos of the 15s2p single stack
And looks slightly too big in Alessioâs build, inviting mayhem. ![]()
Cool build, does that battery fit into a bigben single stack enclosure? How heavy is the board?
Boardâs heavy but I donât think unusually so. I donât have a bb singlestack box. I think it could be made to work with a thick gasket, but the doublestack box will fit comfortably.
My psychotiller box needs a bit of gasket to squeeze it in.
Will warn you, 3.3v * 2.5ah * 30 cells = 247wh, at 20wh/mile (9wh/km?) thatâs 12 miles (24km?) on a good day. staggerstack 26650 I do not think will fit a doublestack box (I could check if youâre considering this).
Iâd like that thanks a lot. But no rush I am not close to starting that hummie build lol. The deck isnât even here yet.
I agree I have ordered 500+ cells from battery hookup. They are legit.
Onewheels use these A123 batteries I can confirm they are legit beasts.
This is interesting timing because my onewheel appears to have a broken BMS and will now need a replacement.
Time to diy a battery and these show upâŚ
I would have to add a solid inch of thickness to the rear footpad
exterior parallel would probably be the move actually and 16*3 = 48 very conveniently
I was thinking of ordering benâs double stack or mega stack enclosure and running a gasket to get a stagger stack 4P. Iâm used to heavy boards, but this would still be a smaller package than my big bois, and would have some interesting characteristics.
Thanks for the pics of the 15S2P, btw.
Yow! @Pedrodemio cracked his deck, might want to reinforce if adding crazy weight. Canât wait to see this crazy thing. ![]()
bummer. I have 25lbs of batteries strapped to a 9 ply flexy deck that has been okay. Could add another layer of cf to the bottom, but this thing feels hella solid.
Could also put it in a TB40 that is allegedly comingâŚ
