connect lipo battery to euler bus

Also, I don't think the charge current is anywhere as high as you think it is... the AXP209 is capable of charge currents of up to 1.8A, but I haven't seen the pine64 report anything above 600ma charge current, so it certainly isn't configured that way on mine, and I haven't touched the AXP registers. The AXP209 defaults to 500mA or 1200mA (automatic determination based on input supply stability so it looks like it must be limiting to 500mA ... but then again, the register defaults also indicate the charge LED should work out of the box, so some register settings certainly appear to have been changed to less than optimal settings! 

This seems to be another inconsistency between these boards.  But , if my 8000 mah batt is being fully charged in 3.5 hours (that is consistent between the two machines) then the current has to be somewhere around 2.3 amps.

I think the charge times are definitely affected by what else is plugged in, whether the hdmi is running, and other factors... but, also I think that the machines are not consistent in this regard either; I'm hearing all sorts of conflicting statements (and I only have three boards to test on).
