and since my system is 10s isnt it not possible for my pack to produce more than 42v? Wouldnt that keep me under the 50.4v limit?
If anyone else can help me understand why my FOCBOX is fried let me know.
Also, if I wanted to have a go at replacing the DRV8302 chip myself if enertion doesn’t cover this under warranty, which it looks like they may not, what tools do I need for SMD? Solder paste, heat gun, soldering iron?
It is just a misunderstanding guys. @CarlCollins is just trying to do his job by trying to answer questions on the forum (which he isnt really required to do) cut him some slack.
I think we all appreciate that he is active and communicating. I didn’t mean to crap all over that. It’s still important to point out that this is a setting that might be dangerous to 12s riders.
Any safety relevant issue is worth discussing to death…
Wait guys can we focus on the issue at hand? I know entertion support is a fun topic, but can anyone tell me if my settings exceeded the specs of the focbox? Thanks
Tell us your setup. Is it a dual or single? Looks like you have a 10S battery? What type of motors and KV? What type of batteries are you using? Just reading around the forum it looks as though quite a few FOCBoxes are burning up right now. Maybe QC was rushed?
I have two builds with the same exact setup. I also have another same just with Samsung 25R’s. You’re settings are perfectly fine and even conservative. You can actually run 40A Batt Max each and be fine. I run at 30A to be safe and for longevity. Here’s my settings. Been using the same for a couple years now.
Motor Max= 70A
Motor Min= -55A
Batt Max= 30A
Batt Min= -10A
Min ERPM= -60000.00
Max ERPM= 60000.00 <----- This is what might’ve killed it here
The DRV can be blown and have no visible damage. Reflashing can fix software issues. I haven’t seen a DRV error caused by a software issue before, but it’s the first step in diagnosing a problem when you don’t have test equipment on hand.
If your board works for 100 miles that means the issue is not from the factory,
100 miles is a lot of time for something go wrong.
So it’s not a manufacturing defect, you need to purchase the platinum warranty to get replacement or repair.

I had DRV8302 issue on my VESC 4.12 recently, it appears to have been resolved by reflashing the firmware (or updating from 3.37 to 3.38). But haven’t had time to test my board intensively, but really seems to be fixed now.
Obviously, I had no permanent issues, just loss of power and an error for a second during rides.
I guess FOCBOXs are rated for 100 miles run within spec, how laughable. I have another focbox that has run with canbus with this one for all 100 of those miles and doesn’t have any issues. I will never by an enertion product again. Time to learn SMD.
