Tacon 245kv mono drive and 10s4p... Will it work?

So, I can use 245kv with 10s, just have to tone it down a bit?

@Airmacx that is what I take away from @chaka’s post, but he should confirm before you commit that config.

According to Chaka 60,000 erpm

thanks @chaka

I got a 190kv, 10S, 83mm, 15/36 and get a real max of around 38kph fully charged, which is around 85% efficiency, overall I guess efficiency is more like 80%, like 35kph (especially when the battery is at less or around 50% charge).

A upgrade to 213kv would bring me up to a max erpm of 62174.70 with a theoretical top speed of around 50kph, assuming that I only have between 80% and 85% of efficiency I should as well still be fine in re to the 60k erpm mark right?

Need to think about it all, guess I just go for a run :slight_smile: Really wondering where I loose efficiency.

Keep in mind you can easily reach 100% efficiency speeds during a decline.

254kv at 10s is not a very good idea unless you don’t mind drv failures. It will work but it will eventually cause failures and faults during braking.

I guess so. Not having many hills here though.

But that basically means what you guys are saying is: better stay low KV and pimp your gearing and wheels if needed.

yep! There’s a reason the big players are staying under 200kv. My Evolve GT runs a 130kv motor with a very low 2.13:1 reduction.

go 8s 4p or 5p and ur good to go it will also be easier to find a charger if u wanted that instead of a bms

Well, I already have the motor, so do I just build a smaller battery pack?

im running the same setup as u

either smaller pack, or limit the eRPM on the VESC

Okay, probably limit the eRPM, since I already have all the batteries. So what exactly does it do? It limits the RPM of course, but physically, what will it do, just slow down the general speed of the board?

Also, how do I limit it? Software? Can it be done on the VESC itself?

Yea, the VESC won’t accelerate past the limit. You do it through BLDC tool (VESC program)

Ah cool, what should I limit it to? Luckily this is an option, I don’t think I had an option to return my motor haha, so this kinda saved me.

60,000 erpm. It is more preferable to get the right motor, but if you don’t want to this will work as well.

Yeah, unfortunately I got my whole deck, trucks and motor in one ‘deal’ that costs around the same as just one of the Enertion 2.0 motors. I could get the less expensive one. How much different is it? One is $159 and the other is $219, other than the size and wattage, I don’t see there’s that much of a difference? Is the more expensive one worth it?

since its a tacon u can sell it and get a 190kv motor which is now in stock or go 10s with the tacon but there have been multiple drv failures when running 245kv or higher motors on 10s. or u can simply run 6 or 8s with your current motor

edit this would be the 190kv hobbyking motor which is considered one of the best setups for the vesc

Hmm. Would anyone want to buy the motor? How much would I sell it for? I’d like to get atleast half of what the Enertion motor costs. Would 100 USD be an okay price?

if u go 60- 70 then id take it off ur hands
