Hi Guys,
New to the esk8 scene but loving it, looking to start a new build that will give me really good range and a moderate top speed. Already got evolve supercarve 12” trucks and 97 GT wheels which I love. So onto the drive, I am looking at either Hoyt st pocket rocket 2200w 180kv motors or maytech 6355 170kv motors using maybe a 12 or 10S 4 or 6 P battery set up. And this is where I need some help on matching the right battery with the right motors etc. Nothing is fixed so open to any suggestions re battery’s / motors / drives etc.
Thanks guys,
Maverick

I have maytech 6880s. They are OPed but I love them. I have probably 400 miles on them and I love them so far. They are pricey but maytech has quality products . as far as the battery goes as long as your get a speed controller that can handle the battery / motor configuration you should be good. There is plenty of knowledge on here. Hit tgat search button up top and start reading. If you have any questions along the. Just ask. Glad to have you
The voltage of your battery is going to have more impact on which esc’s you go with rather than the motors. The motors you listed do seem to be decent choices. My first diy has a 12s5p of 30Qs and it was a solid battery. Was easily able to go 30+ mph but didn’t get to do a true range test. Alternatively, you could also go with Torqueboard 6374s. They would be a bit cheaper than the maytech’s and have higher current rating, as well as being able to fit on more mounts since many are made for 50 or 63mm motors.
Hey Lewis-
Good to have you here. Here’s a great review on Hoyt St motors by our own Mike Maner:
What do you consider a moderate top speed? That will help determine whether you need to go 10s or 12s.

Hi Guys, thanks for the response, really feel part of the family. Ok so as far as top speed I think 30 mph is plenty fast enough. Really want to concentrate on the range, the part I’m not quite sure about is how to spec the wax’s to the battery discharge and the motors etc. Can you guys point me in the right direction.
Top Banana,

You are part of the family now, but just be aware that we all sleep in one big bed.
Assume this was vesc. Your settings will depend on your associated gear specs. So better to choose your battery config, motors and vescs before thinking about settings.
Suggest you start with the deck, though. So much will depend on this.
Something to consider is that 30mph may be too fast on dual kingpin trucks…

Thanks for that, so as I see it so far, deck will be 38” x 9” long board using maple ply ( gonna make this myself as have made a few before)
Want to stay with the supercarve trucks as really like them but take note on hitting 30mph, happy to tone top speed down, distance is more important. As for the battery it seems voltage gives more speed and parallel gives distance ? So I thought could I get a 10S5P as a flat battery as the 30q Samsung cells are 18.33mm wide x 10 would give me a battery width of approx 7 1/2” Happy to use either motors as mentioned earlier but which combination of battery and motor and which esc would best suit me getting the most range. Feel free to pick hole in the calls as still getting to grips with it all 
Thanks

Stick with thanes if you want range in sacrifice of comfort
30Q are a favorite of alot of people. They do sag a bit but jumping up to a 5p should help you alot. I have a 12s4p battery in my first build and have seen a little bit of sag on the back half of the charge but its not super bad.
Ok that’s good, so to try and tie it together, are the hoyt pocket rockets the best motors to go with in terms of range, or am I better off with the maytechs?.
Also can someone recommend a esc or a VESC that is reliable for the type of build I’m doing.
You guys are cosmic

Some notes about maximizing range:
- higher kv motors are more efficient than low kv motors
- however running your motor at its max speed is more efficient than at a lower one, so you want your gearing set so that your max speed is not that much more than what you will actually ride at. Use a calculator like calc.3dservisas.eu to check
- belt drives are most efficient if you have a loose belt. To avoid teeth skipping, use a motor mount with 1 or 2 idlers for max gear meshing / the loosest belt.
- gear drives are more efficient than belt drives. @IDEA was going to sell gear drives for Evolve trucks I think, but I don’t know what’s the status with that.
- Direct drives have low resistance when coasting, so can potentially be very efficient. If you want DKP trucks, I recommend checking out the elofty direct drive. I highly recommend direct drives for first builds, because you will run into less issues.
- single drive is more efficient than dual drive. I’m not an electrical engineer, so I don’t understand why
- a cooler motor is more efficient, and motors get less hot if they have more thermal mass. i.e. – larger motors are more efficient. (Also open backed motors over closed ones, unless you plan to ride in a dusty / wet environment)

As for battery size here is a battery calculator that @thisguyhere made for people to get a better idea of how big their batteries will be as well as how much he particularly charges for his services. I don’t have any of his batteries yet but I have heard great things about his work.

The range is influenced by many factors
- Battery capacity
- Supply voltage
- Motors type
- Gear type
- Regulator type
- Driving style
- The rider’s weight
- Type of wheels used
If you are building a smaller battery pack, e.g. 10S4P, you can use 30Q
If larger e.g. 10S6P, the Samsung 35E is a better choice, it is related to the parameters and characteristics of battery discharge
I installed a 10S6P battery pack built with Samsung 35E in my X7 board, last year I traveled 138 km on one charge, I think it’s a good result 
I used cheap 5065 140 Kv Racerstar motors, so with a small kv

Solid list, don’t forget about outside influences as well.
Wind, drag, surfaces and the rest. You can lose miles on rough roads vs smooth.

I think a 10s5p of 30Q would be a good quality battery for what it looks like you’re going for. Much bigger and you’d have to double stanck and the board would just get heavier and heavier. You’re probably not going to need massive motors for this but bigger is more efficient so view it as you will, just as long as they fit on your trucks(assuming you go dual drive).
Hi Tom,
Really interested in the x7 build, if I can get any where near your distances I would be more than happy.
You comment on lower Kv motors which I think makes sense, but as always I guess there is a pay off. Reduced top speed ?
Also you mentioned about using larger wheels such as the ABEC 107, I thought that if you increased you wheel size your distance decreases or have I got that all wrong.
Although I love my 97 gt wheels, I also own a set of foamies by slick revolution, these are a kind of road / AT wheel measuring in at 120mm, could these be better.
Does the X7 use direct drive ? If so what is the gear ratio and how is it more efficient than belt drive.
Sorry for so many questions but I really am excited about my new build.
The other areas of help is what esc do you use and is there anything special about the electrics or the bms. What make of remote controller are you using.
Any further assistance or guidance you can give really would be very much appreciated as I would imagine you’re a very busy person so thank you for your time.
Very best regards
Maverick

I install motors with a small KV because my gear drives have a small gear ratio, i.e. 1:2
-
The maximum speed is 44 km / h with 5065 Racerstar 140kV motors and 48km for 6368 FlipSky 140kV motors
Gear drives require the use of large wheels because the drive housing has a large diameter and using a large wheel increases the clearance
Of course you can use 97mm wheels, sometimes I mount BOA wheels with 100mm diameter,
If you also have wheels with a diameter of 120mm with an ABEC type core, you can use both types of wheels, but I do not know which will guarantee greater range
In this photo you can see the clearance in the board with mounted wheels with a diameter of 100mm
Currently, the X7 has a gear drive installed for the larger 6368 motors
-
The change of motors reduced the range by 10-15%, but now the board has phenomenal acceleration, and the gear drive is much quieter
-
Gear drive efficiency is about 20% higher compared to belt drive
-
I do not use BMS because I wanted to build a single-layer 10S6P battery pack, so there was no space in the housing for the BMS, in addition BMS is not necessary for such large packages if the package is made of good quality cells.
However, I look forward to the serial production for FlexiBMS Lite
- I use the DIY Benchweel remote control in all of my boards
It looks terrible and has basic functionality (it is primitive), but it works perfectly. I appreciate the low power consumption needed for long range boards
In addition, you can buy the receiver itself and use one remote control for several boards

Hi Tom,
Firstly thanks for all your help and advice so far, I think I’m happy to go ahead and start ordering for the new build.
So firstly can you supply the direct gearing that will fit the 5068 Racestar motors that I will be using on my evolve supercarve trucks and motor mounts. If you let me know the cost and shipping and how to pay I can arrange.
Secondly would you consider sending me a list of parts that you have used to build one of your boards as that way im sure that my build will be ok.
Once again very happy to pay you for the information as you have been super helpful to date.
And lastly I didn’t know you could charge a lithium ion battery without a bms, are you using a balancing charger and if so can you charge the battery while it’s still in the board.
As already mentioned I’m fairly new to this scene but so far your builds and information are exactly what I’m looking for from my build so just got lucky I guess but as I am taking up your time I only feel it right to offer to pay something towards your expertise.
Hope that’s ok,
Best regards
Lewis
