Sure. They'll make the hub casing cooler. But they wont' make the *motor* cooler (not enough to make much of a difference, anyway, at heat levels that are requiring heatsinks to start with), until you create a heat path for the motor heat to reach the casing better than the air that's in there righ...

Which explains why your motor is getting hot, if it's only meant for 1500w or so. ;) Yes exactly :lol: :lol: But in all honesty the hub doesn’t get to hot compared with running the stock controller that came with the kit. Since my set up is new I stop every few miles to check the motor temperature ...

Is it already set to pull 80A? Or is it limited to not abuse the 50A battery you have now? No no I have it set to 40a with my current 48v battery. I would be scared to run 80amps to a 50abms lol But yeah even with my new battery that’s 60abms I probably won’t go past 50a for the constant current. B...

Don't know how you missed it. If you clicked on the link that amberwolf provided, it's mentioned in several posts on the first page of results. Yeah I didn’t miss it, I clicked on the link. I was meaning that this is the first day I’m hearing of fluids being put in the hub because I am new to eBike...

Can we assume that this is a whole battery, and not just a BMS for your old battery? Yes it’s a new battery with a new bms. How much more power, and thus how much less range, depends on how much faster you go, and how much harder you are accelerating. It also depends on your controller's capabiliti...

Hub sinks won’t do much, or anything, if you don’t add fluid PS. If you're doing it for the looks, then you could even paint them, but maybe add wiring for LEDs too. OK this is the first I’m hearing of this Statorade. That being said I would think the heat sinks along with dissipate a lot of heat b...

So I just ordered 72v20ah60aBMS. My current battery is a 48v30ah50aBMS,. So super excited to have the extra power now! Just have to wait a couple weeks :shock: Can anyone share their experiences coming from 48 to 72?? So my current 48v30ah = 1440 watt hours The 72v20ah = 1400 watts hours also. So do...

Sounds like I’ll probably go with the heat sinks for cooling. Is there any place you can buy some anodized red ones or other color options?

Yes they do work. It goes like this Hubsinks and some sort of heat transferring fluid in hub > Case cover drilled with air holes > Heat transferring fluid alone > Hubsinks alone > A sock soaked in water wrapped around hub > nothing ( bare hub). From what I have researched. From best to worse. What ...

POUR YOUR DRINKING WATER ON THE HUB - You can probably extend this idea to riding with a bottle that will constantly drip or spray h20 onto hub..

That’s such a simple and great idea to just simply pour drinking water on it. You could even freeze a couple of water bottles.

Hello fellow E-bikers! So I stumbled across this heat sink kit that I’m sure many of you are familiar with. I would love some feedback whether these kits actually help? In theory this seems like it would lower the heat. Do any of you have experience with these or have you heard any positive feedback...

I recently started using a Sabvoton controller and it came with the 750C display and I’m loving it so far! So yeah the 750c would be a good option for you.

DC circuit breaker instead of a fuse.

Yes this sounds like a much more practical approach using a breaker. When I get my 72 V battery I will go this route for sure! Thanks for the input!

Hello everyone, hope everyone is having a good day! Going to post pictures of my current settings and would like some Input on my settings to make sure I have this right now. Maybe some of you remember my recent post but I blew my 50 amp fuse on my battery because I had the boost and flux weaking tu...

/MT420 brakes, Well I can comment on those M420 brakes. I installed these on my first E build and running with 203mm F/R.. These brakes have amazing stopping power. Also have the MT2000s on another E bike and there’s no comparison. They’re definitely good brakes for the price range and then being S...

What is a good/decent e-bike kit that isn't terribly expensive?

What type of riding are you doing? Also is this on flat ground hills or…

What kind of bike are you trying to convert?

Just some stuff to think about.

Thank you for the info!

I adjusted the boost to 75a If your battery was designed for only 50A, running it at 150% of it's designed limit may not be a very good idea. Yes I very much agree! I wasn’t going to turn it past what the BMS could handle but the first reply was suggesting the BMS would protect the battery and turn...

Yes that’s correct it actually didn’t blow right away. I adjusted the boost to 75a and I’m guessing I rode 2 to 3 miles before the fuse popped. I will absolutely keep extra fuses with me from now on! It’s funny because I have a tool bag with basically everything I would possibly need except those da...

Update on my testing today :shock: So I had to push the bike home 11 miles because it blew a fuse on the hot battery terminal. there’s a 50 amp fuse on the red/hot wire and as soon as I turned up the boost it popped the fused and I completely forgot there was even a fuse there because I had it insid...

A BMS is safe by definition, because it will cut off power if you ask too much. So you can play with you controller settings without worrying about damaging the battery. Yes that makes perfect sense thank you! I will play around with the settings now and do a test ride. That being said do you have ...

Hello everyone! First post here and I’m excited about joining this forum. There seems to be a lot of information on sabvoton controllers :) I’m fairly new to the E bike world as far as building E bikes. Everything is working great on my bike and I’ve learned so much info over the past several months...
