Metr pro works on an Apple Watch doesn’t it?
I know it works on Android Wear so it should on the Apple watch thing.
That’s probably the easiest option, but i already have the Davega and i want to make use of it
Getting back in the saddle on this build with 2 months on the clock.
I mounted the major components in the frame with dual lock on bottom, and EVA foam on the other 3 sides
This is the control panel holding a QS8 loopkey for each set of Solos, a charge port, and a parallel port for range extension shenanigans. It’ll get mounted on the left rail with the wires snaking through the frame material to bypass the deck weatherseal, and get its own sealed cover
And here’s a block of HV voltage stepdowns and an arduino/solid state relay so I can power running lights off of Vbat and make the tail lights flash under braking
The remaining challenge is to keep the whole shebang from becoming spaghetti, since I’m almost out of space

looking awesome. That front area looks like a foot trap if you even need to run off though

Added benefit, automatic smoke machine. Imagine the 
ambiance (very rock n roll).
Thanks! The front mechanism is as low as I could make it, but yeah it’s a bit of a foot funnel. My previous bikeboard had a milder version of the same problem though, and I’d like to think I have a bit of muscle memory for dealing with it.

This is the second LLT unit of mine that has been busted out of the box in this fashion. The pack is manually confirmed to be at ~3.49V/group to within 10mV. Has anyone else been getting this?

Haven’t seen this before, nope. Second BMS for the same battery(?)
My gut says it might be a hardware/wiring issue (not a bms issue) because the battery is the common denominator. But you’ve probably checked that already

No, the one for my 10s build missed cells 8-10 in the same way this 18s model is missing 1-4. I’m probing at the plug head to confirm that all the electrons are where they’re supposed to be, so the problem has to be downstream of that.
Can these things get messed up by plugging in the balance leads before the main ground? I’ve heard of that for some other brands of BMS.
I always plug in battery ground before balance.

I had some wonky readings on a JBD (LLT) BMS when I connected to it before the main B- was connected. I didn’t do any damage to mine, but I can’t say for certain that it wouldn’t damage it. Read ok after all was fully connected.
