Are you just in the US or somewhere like NYC or LA/SoCal or Chicago?
Shipping batteries is better avoided, but possible if it’s not international.
I am in the bay area

@Skyart is a great battery builder in Oakland.
I bet if you contact them, they can hook you up.

I was looking to build the pack myself, just to give it a try.
That’s not recommended. You will probably spend a few months and many hundreds on tools just to make one battery, not including the cost of that battery itself. Plus it’s not an easy task to make a SAFE battery. It’s easy to make a bomb by accident.

I was also considering taking smaller packs a wiring them up in series. For example 2, 5s battery’s put in series. How many Ah do you think the pack would need to get 6 ish miles of range?
5Ah (= 5000mAh) at 10S (42V)
But if you use the cheapest 5000mAh 5S lipos you can find you might have bad results as they can just puff and die, possibly in a spectacular fire.
You need to get ones with a high enough C rating. Higher the better, and most of the C numbers are exaggerated or straight-up lies, but above 50C or 100C would be best. It’s hard to know for sure since accurate numbers are hard to come by.
And I also recommend a BMS for them
Yep, I know. I have and use hobby grade rc’s with the same lipo’s, so I know the safety. I have experienced puffing before.

Do you think these would work well in the board?
This is five 2S lipos, but the process for two 5S lipos would be similar.

It’s hard to say because I don’t know the true specs on those batteries, nor do I know how much power the Blink S draws.
Would it be possible to wire the battery’s directly to the esc rather than to a BMS and then the esc?
Sure, but then you have to take the skateboard apart every time you want to charge it.
F that.
The BMS is for charging.
Oh. Ok. I was considering 3D printing a battery box that could un-clip. The stock compartment is really thin, so the 5s lipo’s wouldn’t fit anyway.
Then use five 2S lipos.
What’s the upside in that?
Maybe five thin lipos would fit better than two thick ones.
They still wouldn’t fit. The board use 18650’s I believe, so it is about the height of one of those. The compartment is maybe 1 and a half inches tall. I will tear in apart tomorrow and get exact dimensions.
