I would recommend getting focboxs just because they would be more reliable on an off-road board. Btw if your on a tight budget Keda 195kv motors are a great steal, much cheaper than those of you listed and very reliable, well mine have been. They have taken a considerable knock at about 30km/h into a concrete pillar with only a scratch.

They have two versions 6364 and 6356 (listed as 5663 for some reason) I have used both

Might want to re think that battery. It is a 2s battery which is far below what was offered as the common range of 6s. I suspect you might be wanting to run them in series which will still only get you 4s. That motor is appropriate for 6s-10s in my opinion.

He put ×5 which I assume means 5 2s batteries in series to make 10s

I was going to buy 5 of them

and put them in series to try and mimic this build by @Namasaki, I guess I should’ve specifide that, my bad. And I think by doing this It’ll hopefully work.

Exactly

DOH! I read that as 2x lol prob. because of the 2s… Makes sense now!

Much better looking list of parts now make, should make for a damn good board

@J.Biggs I would not recommend 5ah 30c packs even for a street board let alone a EMTB.

I would recommend no less that 60C and preferably something closer to 90c or even 100c

I was going to use the ones in your build but they were out of stock when I checked. Thanks for the advice. I wasn’t to sure if it was gonna work.

I think you will have too much voltage sag with the 5ah 30c there is another source for high quality high output Lipos https://www.smc-racing.net

So somthing more like this with a 130c burst with 90c constant?

I just found a site that offers 100c for $45.50 if you buy five of them, I dont know if there credible though.

I’m not familiar with promatch. The graphenes have a good reputation

So I found a new motor because I didn’t realize the other one is rated for 6s not 10s so here is my new motor I’m planning on getting.

Alright, looks interesting and new :slight_smile: I´d use a smaller BMS for charging only for this board. You can´t use the BMS for discharging too low anyway, so i would only use the charging and balancing aspect. This way you are eliminating a factor for performance. The next limiting part would only be the two focboxes, but you´re able to pull some nice juice out of them before something happens :wink:

So, your saying don’t use the BMS I found, wouldn’t a weaker one not work, or are you saying balance charge them each separately. One more question what do you mean by limiting factor? Thanks for the help.

Alright, to make it more clear. This BMS gives you a bit more safety, but will limit your setup. Don´t get me wrong, 80A continous can definitely move things :wink: A smaller charge-only BMS will alow you to bypass the bms for discharging and will only be used for charging and balancing your lipos. It´s much smaller and cheaper. Something like this one: https://www.ebay.com/itm/282923151393?ul_noapp=true

What i meant with limiting factor: You´ll find a bottleneck in every system. But you´re able to get all parts to about the same level and that´s the art of building. In your sytem, the batteries are able to pull more than 80A and both focboxes are able to pull more than 80A together. In between that, there is your BMS which, with 80A will be the limiting factor. It´s better to let the Focboxes enlarge their full potential and let them manage the maximum limit for maximum fun :wink: Before you buy one, pls do some research on BMS for charging and discharging vs. BMS for charging only, bypassing discharge

Wow, that was very helpful thank you.

sure thing :wink: Have fun building and just use the search bar for some topics regarding your partlist. If you´ll stuck somewhere, just write the question down and we´ll figure it out!
