stopped at 133. Up/down buttons are ridulously difficult to press also...
any other suggestions?!?!
What batteries are you using? How exactly does the error occur? Instantly on power up? When you press the fire button?
Two things you can try - one is to run the Battery Analyzer under Escribe; the other is to show your batteries voltages on the display or check them via device monitor. Maybe they are not equally charged?
Then its most probably configured correctly in escribe. Must be the wiring? Care to take some pictures of the inside?
so after I install batts and press fire i get a evolve dna200 splash then blank. If I press fir I get an empty batt icon and 'check battery' error. The batts are equally charged going in but I guess I could install and let it charge balance them through usb?!!? sound good??
i think you should get a boxer splash after the DNA one!!
What does device monitor report as the battery voltages before you press the fire button?
I am guessing it won't even charge via the USB cable. If your batteries are good, the issue most probably is related to the wiring for the balance charging.
i cant see it in escribe. Nothing appears in USB devices either in OSX or in VB...
If it's not showing up under System Report under the USB device tree, it sounds like a bad board.
on USB with batts in i see the lightning bolt/charge symbol. Im sure the batts are good...
I wouldn't necessary write off the chip as bad. The fact that you get power to the when plugged into the usb port shows the chip and USB port are working fine.
Are you sure you are using a data cable to connect or is it just a charging cable? I'm am still guessing that it was simply wired incorrectly by esauce.
If you don't mind sharing pictures of the inside, i can try to see if anything is obvious. Regardless, sounds like you will need to return it to them either way.
Got it to talk to escribe. For some reason my MBA wasnt seeing any USB devices...reboot sorted it. I can now see that Cell 1 has no voltage regardless of which batt is in there so looks like a solder joint has broken or something. Already arranged a return for a fix! I might have a quick look tomorrow and I'll post if there is anything interesting going on..
Cheers

ps. Alex at esauce said it was tested before shipping so either Im an idiot (likely) or something came loose in transit (also possible).
Have to say, in spite of the glitch with mine, esauce is a great vendor!! Highly recommended. Alex has been on line with me trying to solve this problem up until a few mins ago (its 1 in the morning here btw)...really spectacular customer service.
Glad to hear that is working out for you and things are being handled the right way!

I inquired with GV and they said that esauce builds their own units. So from that I'd reasonably assume that GV wouldn't be involved in testing a Boxer from esauce either.
They also noted that if the wiring is not set up correctly, the 133W configuration won't work correctly regardless of the settings in escribe.
Here is Evolv's DNA 133 Wiring Instructions:
"To use 2s mode, you have to make taps from the battery as usual, but because there is no third cell, the tap connection labelled 3 must be connected directly to the tap connection labelled 2. This can be done in the wire harness or by jumpering the connections directly on the board. This is the ONLY way that 2s batteries will work and balance correctly.
Other than that, it is just a matter of selecting 2 cell rather than 3 cell in the battery section."

If set up correctly, cell 1 and cell 2 will display the voltages of battery 1 and 2 in escribe and cell 3 should display .1V or less (otherwise, the chip assumes you're in 3S mode regardless of escribe settings and one gets "check battery" because cell 3 is an invalid voltage). If that's not what is shown in device monitor, than the wiring is probably incorrect.
