I want to make much larger Battery!

Hey, I want to create a much larger 70v 20s battery for my New Carbon Gt. I like to ride about 50miles a day but at the time I wait out a massive recharge time. So my plan is to create a battery that will fit the bill. Would love to do 105v 20s but I still am trying to understand the basic principles behind the BMS and weather I can increase the Mah of the cells. I have someone who can do the battery math for me but he said I need to know the basic perimeter's for the device. Here are my questions... Mounting problems aside.

1. Is there a max voltage I can push through the BMS or will it monitor and balance the output to the motors. Dumb question but I want to make sure I am not overloading anything.
2. What is the base mah of the original battery pack and can I increase them? What will that do? Is it necessary?
3. What is the current specs of the Carbon GT 3 battery?
4. Is this possible? and are there things I need to know before going under the Iron.
5. Someone explain all of this to me like I am an infant child who needs to learn all of the language. Or point me to a site where I can do the research. It's been a difficult site hunting so I am trying to find a good source.
Thank You

 

What is the C rating? Can I make this Board faster? Or will I need a new ESC and Remote? I don't mind having to replace these items just need to know if anyone has the deets.

 

First things first, is you can't be change the voltages on a board like that. The whole evolve system is based around 37volts nominal.

Secondly if you want to increase range you'll need to increase the Ah available to the board. Meaning you'll want more cells in parallel.
A configuration used that you can expaned on is 10s4p, as the stock BMS can support that.
You can add more packs in parallel to increase the range but you'll need to get a new BMS.
Even when people build boards they dont really go past 12S as the voltage really indicates the max speed of the motor. (Read into motor kV ratings)
There is lots about building batteries on this forum and esk8 forum.
I would say, before even attempting it you'll need to know exactly what configuration you want and the basic principles of how voltage and amps affect the system.

Good luck!

 

Thank you Isaacm. I have to keep searching I guess. It's been hard to find the right info but ill have to reach out to the service department of Evovle to grab info.

 

I have a 10S6P (18650 Samsung 25R batteries) in my custom built deck, and have about a 30-35 mile range with street wheels, and about 20-22 miles with my AT setup. To go 50 miles in one charge, you'd need some higher mh batteries, and at least a 10S8P battery pack, which means you're going to need a longer deck. Long Haired Boy on the forum will make a custom pack for you and modify your board. Info here: wholesale blank longboard decks

You really want to go 50 miles in a day? I've done 20 miles at once, and it takes a toll on your knees and back.

 

Are you trying to fit this inside the Carbon GT? Cause the most you'll be able to fit would theoretically be a 10s5p battery and that's sketchy at best. This'll get you 540 Wh compared to stock's 360 Wh, and I'd say that'd get you at most 30 miles if you like going max speed. A more realistic setup would be a 10s4p battery giving 432 Wh and only about 24 miles ish.

 

What about a split battery setup with a battery in the stock location and a battery in a box like a lot of the mountain boards?
