MTB Dreamin' How is it looking?

Thanks Dude.
I thought I was getting by too easy…
So bear with me.
for charging combine these 2 items?


Battery wise, I would like to get 10 miles(16km). I would really like 15 miles(24km) but I also need to be able to lift the board… so I think I can compromise here.

I really, really struggle with the whole Lipo Battery thing so much.
Would 2 of these cut it?

Or are these the way to go? they seem massive…

Is there an obvious combination of Lipos that folks typically use?

I would also welcome suggestions on getting chain drives.
I seem to only see the Momentum Boards one. which I think will do.

Much appreciated.

Have you possibly looked for etoxx?

The hobbyking power supply you linked is out of stock, as min for me, but they should have special power supply for the reactor charges as far as I know.

I would prefer graphens over the turnigy lipos.
12Ah should give you close to that range you want, but that depends on how and where you ride.
Why you want to go with lipos?
There good reasons for it, but the higher the range expectations the less sense it makes to go with lipos.
They more Heavy and more expensive as they usually can’t handle that much charge cycles as LiIon cells.

About chains, shoot @NoWind a pm or a mail via his site.

I‘m sure he can sort you out with the drive train.

yeah, that is some nice stuff…

To be honest I am not sure I really want Lipos.
never used them before.
when I was looking at the smaller ones it seemed attractive because of the price and availability…

but with the 2 Graphene 12000 and chargers I am getting close to $450.

That Etoxx stuff is super nice. Off course after looking at the chain set up I start looking at the drives…
freaking sweet.

this diy stuff is so nuts, as my thinking I could keep this relatively cheap has already been blown out of the water…

I say if you actually use your board and plan on keeping it. Lipos ain’t the way.

I’ve gone through maybe 40 lipos and the cycle life is just horrible granted I don’t always discharge but more than often I do. I use to swap lipos for additional range but they’ll possibly eventually puff and if not they degrade fast so you’ll end up getting 60-70% range from a battery.

Which means you’ll be buying more lipos constantly if you actually use and ride your board.

Vs if you go Lithium Ion 18650,etc. Your battery will last for at least 2-3 years with no crazy capacity degradation unless a cell is bad (not likely) and if your BMS sucks or you don’t charge to 100% on your 18650 battery.

Not to mention charging isn’t as simple either plus you’ll have to use a loop key.

I was using a HobbyKing 350w 25A Power Supply (100v~120v) with an iCharger 208B+ and Parallel Charging Boards to charge multiple batteries. It’s also bulky when charging.

There’s always the discharge only BMS option for one plug charging and unrestricted Lipo power.

48V and 62.5 amps. Makes 3 kW of raw power. That’s, what i call normal :face_with_hand_over_mouth:

There some volt missing for 12s thou :sweat_smile:
And a bit much amps, no?
I guess you charge usually all your battery packs at once in parallel?
That would be actually pretty fast :sweat_smile::ok_hand:
But a bit dangerous

It’s for charging two 10S6P 21700 packs in parallel. You know, Baja :wink:

Mhhh naah naja yes, but
Lipos have there place in light mtb setups.
The moment you don’t mind about range but want to go as light as possible without to lose performance.
I would say roughly about a range of 12-15km plus there is the point where LiIon win in nearly all points over lipo packs.

Yep. Thanks Dexter. Since you you are not really working on much these days you should come out with more batter options… :slight_smile:

Both are strong.

And you can throw three together to work together for 9 kW.

Ok. So funny how this Love(addiction) for esk8s works.

I have found a loophole in my head to justify spending more money, so I can move ahead with this build. But I think I am getting by pretty easy really…

So let me kind of start over with a parts list.

MBS Comp 95 complete. Got it for 240 on ebay. gets here tomorrow.
Matrix II trucks. Rockstar II hubs. 8 inch tires.

Boardnamics mounts.

Momentum Boards Chain drive Kit.

Focbox Unity.

Mini RC remote(cause it’s my fav)

Maytech 6374 170kV sealed motors. (will run unsensored as one has a bad sensor).

2 Meepo ER batteries to make up a 10S4P 40T pack.

Pelican 1020 Micro Case for the ESC.

Pelican 1150 Case for the batteries.

So my genius idea(the loophole) was to pillage a couple of my smaller builds for their Meepo Battery.
I hope that with the 10S4P 40T set up I can get 10 miles or so of good riding time.







More to come as parts show up.
