Hi Dave,
I have few questions:
1. How long does the backlight stay on? I have troubles with my BM829 - It goes off before I can measure anything. If I had a choice I would like it to be changeable in setup to something like 2, 5, 10 or 30 minutes. Yes, 30 - that's the one I'll leave it on.
2. You mentioned cut off voltage. What's the maximum operating voltage (not the absolute maximum, but safe operation)? You say that battery life is good, but I'll put rechargeables anyway - bluetooth, backlight, logging ... etc. I just wonder if I can put Li-Ion or LiFePo4 (two of them with connector batteries).I'll probably use NiMH, but I'm just curious.
Edit: I forgot one: You mention shipping to EU using EU company. Do you have any news on it? Will I be able to get mine shipped from EU if I back you on kickstarter or you'll have separate sale for the EU (so I don't pay tax)?
