Extra safety 🤷

Maybe… but the raptor 2.1 e-tray does have a fuse. Looks like an ANL fuse in a fuse holder, and judging by other comments in this thread it’s at least an 80 amp, possibly 100 amp.


#1687

In the words of Jeff, he has never had one spark but it is recommended to have a fuse.

:smirk: :ok_hand:


#1689

But i think the unity can take up to 300A , why put a 80A fuse ? :stuck_out_tongue:


#1690

Matter of preference. I, along with a few others, would hypothetically rather risk blowing a vesc under some insane (hopefully unachievable) condition than blow a fuse and immediately lose control of your board when in reality the vesc might have been able to take the Amps. I don’t like risking the unity but I don’t like risking my whole self either.


#1691

This is my reasoning too. I’d rather burn the whole thing to cinders than have a fuse blow randomly while doing 40mph.

EDIT; I do advocate fusing the charge port and cell level on the battery though. This will protect from a charge related fire.


#1692

Thank you for adding the charge fuse note! I should have stressed it earlier as well. On that note, @hyperIon1 and @hyperIon2 are working on including fuses in this exact fashion on their battery pack charge ports. This should have been standardized long ago!


#1693

:open_mouth: i rather get my vesc blow than throw myself in the road about 25mph :smiley: :smiley: im so confused hahaha if i get fuse or not

Links incoming, one sec

Basically, use an Xt90s loopkey for a physical on/off switch (you can have a push button start switch on top of this too still). If you want to protect your esc more than yourself, fuse the loopkey. If you want to protect yourself a bit more but risk damaging components, use a thick ass wire (10 AWG, high quality) to effectively DE-fuse, the loopkey.

I know it sounds silly but could someone buy one of these after I send them PayPal or cash app, the digikey website refuses to change to states shipping for me :sob:


#1696

Check Mouser electronics. They ship to us and are cheap, quality parts


#1697

Have you tried visiting the American site instead of the Canadian site?

Change the .CA to .COM :wink:

#1699

Hi im sure someone can help me here , i have the 2’q raptor drive kit , can someone tell me what value i need to setup for rpm (test erpm) in the unity tool, now its at 14 …Thanks


#1701

10, you can also just run the config routine to find this number if you click that button.


#1703

Do i need to press the power button for a period of time to activate Bluetooth or something like that?
I can’t connect it !! i try on iphone ,mac ,windows
My mac see the unity but nothing happend when i press « connect »and can’t see the unity on windows and im 100% i have Bluetooth on windows…
What i do wrong??..


#1704

I use my phone and in order to connect I have to have the scan going at the same time I connect. Im not sure this is the case for everyone but it workes that way for me.


#1705

At this stage the Bluetooth function only works for Android phones.

I feel like maybe we need a unity FAQ thread :joy:
