Explain pleas XT60 rated at 30amps continues 60amp peak

let’s look at volt drop

XT60 takes up to a AWG 12 cable that cable at 55v with 2% volt drop is 25amps ish

I can pull over 40 battery amps for some time riding up hills on urethane dule drive 6amp cruising at full speed on flat road to me the XT90 is a good balance at 40cc 90mc with out been over kill of the XT150/250

Test p group. Connecting wire length is critical.
A bit of slack, should allow for deck flex.

And yet the Unities shipped with xt60 with 120A battery amps and none melted… The same way a XT90 on the kweld spot welder passes 1500A pulse currents with no problem… Take ratings with a grain of salt and assess per application basis. The mfg ratings are often much below safe limits with legit parts.

Wait… What? Lol

Look at any decent hobby stress test video of a genuine XT-60 connector on YouTube.

P.S. I can throw some 2/0 AWG on an XT-60 if you really want…

Thank you! I appreciate the effort! However I am looking for something even smaller that will just display current and voltage. But it looks like none of the ones in that size show current. Only volts.
I’ll give alibaba another shot

1600 amps had problems changed to xt150 still warms up but manageable if slow down a bit this is also ms I can’t get up a hill in millie seconds

Not with that attitude.

Im looking for a smart BMS that can show the cell voltages on my phone, is this a good option or is there any better ones for the same ish price?

I’m a fan of xt90s, but a xt60 can do way more than 30A and probably good for most of the average riders power demand @Darkie02

I think I did post that video not only one.
Nice real life testing

I agree with Andy. Original Amass XT30/60/90 connectors can handle a lot of current. The knockoffs are somewhat more hit-or-miss.

How can one tell a real Amass vs a knockoff?

This is what you want brother. Might be able to find it cheaper on Ali, but i have had good luck ordering straight from the source.

How do we not have a Smart BMS thread yet? I have so many questions about mine that the search function can not answer. Is anyone who is better at making/managing a thread than I am willing to kick it off?

@wandagoner I dont know if you have any experience with these BMS’s, but I have been really impressed with threads you have done before, think you could help us battery micromanagers out? @glyphiks same to you.
