but did it also help you with something? could you run higher brake currents. if yes, how much compared to what you had before?

Theoretically I can run higher brake currents but my brakes are plenty stiff as is

So you just have a box taking up space in your enclosure for no reason? 
Well, if you have space in your box for a box, why not?

Are these rheostatic brake modules based on Ultracaps ? https://www.capcomp.de/en/ultracaps-consultancy-sales.html

As b264 once said: the more parts you have, the higher the chance of something breaking.

Nah, it’s just taking up space for testing and feedback 
It’s not a critical component, so if it fails it doesn’t shut down the system like a switch. As the Battery pack grows in size and power it will be something needed in the future, it will protect your esc and battery from spikes in current, most escs can handle it but your direct discharge battery may not. Everything has limits

They do use 2 capacitors in the same principle as the ultra caps regen function but do not manage storage or current out like the ultra caps. the ultra caps can be used in principle, but cost-effective no. It’s more for solar, wind and water generated power storage and supply systems that cost $$$$

that little bit there that says 10s or below, we discovered that for them when they sent out the first batch. Circuit FW limits are not set to accommodate 12s, the 12s will be in production soon.
As for why?
A quad hub motor set up or any quad out/in runner will slam the battery pack with a heavy current with all braking at the same time, yes the escs will regulate this, but flawlessly? it’s a failsafe that if it fails your still safe, if it does its job your safer.
case in point: current battery build 12s6p with Sanyo 20700c 35a cells intended to drive 4 TB DD motors with 2 unitys.

It’s a good thing to have if it can withstand the excessive current, least time I saw this in motion it was a DIY solution from a Nordic guy who modded his pre built EUC. It would prevent brake cutting when battery was full, on top of protecting it from overvoltage AND overcurrent.
I’m waiting for the feedback, these things should have been around earlier.

Sorry to bring up this older thread, but have there been any developments on this? I’m really surprised these things aren’t in every board already, especially from bigger brands like Boosted seeing as this is a pretty large safety issue for those that live in hilly regions.
Can you literally just put one of these in parallel with your pack and be good to go?

Yes. It’s that easy.
Here is why people don’t use them regularly. If you hit your throttle for 3 seconds, you’ve most likely used enough electricity to mitigate the situation. Unless you’re starting downhill from a steep hill at 100% battery, you will still have brakes. You will never regen more than you’ve used unless you’re solely downhilling and using regen brake.

Yeah its definitely an unlikely situation, but honestly even having to worry about it (even if the odds are low) is annoying to me. Has anyone tested these and seen how well they work? I assume it only works for a short period before overheating.

Maybe I don’t understand it correctly, but having that device to prevent charging the battery beyond a given voltage is nowhere near as appealing as a device that would dissipate the excess regen current that you can’t feed to the battery. Such a thing would still give you some strong sustained brakes even on a weak 10S2P battery that can’t handle much more than 4A charge.

Yes. I have wanted to try this. Theoretically you could set the brake current up to twice as high (parallel regen to battery) and not worry about it.
@cap7ainclu7ch I have been using my maytech one for about 1200 miles. I took it off to save weight when shipping and racing it and haven’t put it back on since. I’ve noticed no difference but am also on a 10s5p 30q pack and my brakes don’t draw more than my battery can handle.
Okay, I’ll ressurect this thread:
Is there something like this for, say, 14s? If not, I might consider having one made - isn’t this basically some diodes (/a transistor), a resistor and a heatsink?
