Is it possible to use antigravity brand "starter" batteries as power source for an ebike? I remember seeing a youtube video of a person powering their 72V go kart using a few of these brand batteries in series. I believe his setup pulls 450A peak and 150A...

https://www.thunderstruck-ev.com/curtis-ipm-system.html how about this kit geared more for low end 26T motor sprocket to 58T axle sprocket? I should be able to spin some tires?

Thanks guys. yeah I know the me0909 and me1507 are two different motors all together. I was curious given all things are the same, if brushed motors have higher standstill torque. I guess they do. But if I'm going to the me1507 32kw motor powertrain system, I should be getting noticeably...

I currently run a me0909 brushed 48v 300A peak motor on my go kart with alltrax 48500 PMDC controller, which is powered by a 13s 44ah lipo pack. I am thinking about upgrading to the me1507 PMAC motor using the Curtis 1236SE controller and a 72v battery pack. If given a brushed and...

Awesome. Thank you!

Does anyone have the frey config tool to program the Bafang motors in the AM1000? The regular bafang config softwares won't connect to the frey Bafang motors.

So I just use the tubing I have now and fit a bending spring inside and follows the steps you mentioned? How would I secure the copper pipe to the barb fittings?

Yeah, I am thinking about upgrading the battery pack as well, but I want to try out this cooling system I am working on. I do have a radiator and pump integrated setup used for overclocked computers and it's pretty compact and lightweight. The lipo pack I have now does pack a good punch and...

I’m trying to develop An active liquid cooling solution for my electric kart build which runs on a 44ah 13s lipo pack. It’s gets pretty warm during extended heavy use (heavy acceleration and hard pulls). So far I have a custom water block put together using multiple small water blocks lined up...

What’s the range of the am1000 if only using throttle the whole time?

Ran into a weird issue while charging. I notice it wasn’t able to reach full charge of 4.2v per cell. During charging the Ir as shown on my graupner polaron charger is around 2-6 mOhms. But once it get close to full charge, it gets stuck around 4.15v per cell and the IR then shoots up to 80-90...

Yeah the resistance is measured from my Graupner polaron pro charger. It’s able to show the resistance for each cell of my pack. On my kart application. I do pull on average 90-120A throughout the duration of my drive, which is almost constantly. And very often full throttle 300A peak from a...

Sorry. It’s 1-2 milli-ohms (m-ohms). Not ohms.

The pack does get hot too. It's not just the cables that get hot. Would running the pack in a lipo safe bag make it run hotter?

I don't have an Ah counter, just an ammeter. The cells are max amps brand lipo pouch cells, combined together to get the 13S 44Ah size. It weighs around 14kg. Pack is made with brand new cells, so 3 cycles. The pack averages about 1-2 Ohms per cell. The power cables are 8awg, which I think...
