I have used 10awg and xt90s for my whole battery and motor setup to allow the best current for high amps to get the most of this board, but I have a bottleneck in my power, the vesc x(focbox) uses 12 awg wire and xt60s. So I’m going to re solder on 10awg wire with an xt90adaptor for less resistance and higher capacity, and lower heat.
Does anyone know where I can get new connectors to attach the focbox to my motors? The motor has a thicker wire and plug
Try to search “bullet connectors” on hobbyking, amazon, ebay You can get them in different diamenters
I usually buy bullet connectors from Amazon, 5.5mm. Usually, motors come soldered with 5.5mm unless they’re hubs.
Actually is not need it to do that, the cables from the focbox are enough for the amps you going to use, also xt60 is enough no need it xt90, bigger not means more efficiency
Just put xt90 on the Vesc-x if needed but there is no need to mod the wire because! The 12awg cable is not the bottle-neck rather the Internal electronics that handle all the current, The guys at enertion would not Cheap out on 12awg instead of 10awg, everything for a reason.
I agree they are anal about quality but also weight reduction which the lighter wire and plug also reduce a fair bit @Blitz I wonder if maybe it was seen as a just sacrifice or a tolerable tradoff
It was probably a tradeoff for performance that the raptor will not use, also the 12AWG is probably cheaper
what I can say is that, If your not very good at opening things and soldering big wires on smaller ports It’s just not worth the risk, also if your Vesc fails well you kinda tampered so Be aware! If you still decide to do so then Please test performance before the mod and after If you find anything interesting share with us.
Will do, I’ll only adjust 1 to make sure I don’t waste more than 1 vesc @Blitz
Good Luck measure twice cut once
So I’ve decided against modding the focbox wires, I’m going to re order my battery adaptors in xt60 links. It will save weight size and a headache
Wait what? You can put on a xt90 IT makes no difference!
there is an amp draw limit better connector wont change that.
How do I put an xt90 on a xt60 unless I get more adaptors and re solder them together?
OK lets be productive!
Now Why get xt60 instead of xt90 does the size really matter to you? you should not use adapters they could just be another point of error or just take up more space. So now your thinking should i go for xt60 or xt90 connectors on all my stuff?
xt90 Pros: you batteries already have it, Soldering 10awg is a lot easier with xt90. It’s a bit more reliable, cons: it costs a bit more and its bigger. And when you said adapters did you mean connectors because all the confusion is from that.
My batteries are 5s, they were made with xt60s. Your video showed me I can put the 90s on my battery and then continue using my xt90 harness (yes series and parallel) and I could easily do the same to the focbox. No the size doesn’t bother me at all but I wonder if I’m actually going to see any benefit to using the heavier gauge wire and connectors when my battery and speed controllers are limited to 12 awg wire, while my harness wires are all 10 awg @Blitz
If you use XT90 you can take advantage of "120A Peak Current Limit " “60A Continuous Current” (as specified on enertions website) Do you really want to be near the edge from the connectors side?
The wires can heat up but the peak is only like 2-4 sec? (for acceleration and uphill I guess) good wires should be pure silicon so The heat won’t melt nothin.
I recommend go with xt90 and don’t worry about no 12awg wire Just play in the safe limits set by professionals.
I like your thinking, I’m gonna order male to female xt90 and re solder them to my batteries and speed controllers as suggested and leave the existing 12awg wires. @Blitz
Those specs are with the XT60, which is built for 60A continuous. And 120A peak is the rating For the Focbox max peak Amp.
So there no bottle neck with those connector.
