Anyone tried these with a 722 or 744T yet?
It should work - but I use an Electrovaya Power Pad 160 (16V) directly into the 702 with no voltage selection or regulation required. The newer PP 130 is 19V and will require regulation for the 7XX series.
I would expect to be able to run the 702 w/o phantom for at least 30 hrs and w/ phantom at least 20 hrs. When I run for 4 hrs the bat doesn't go below 80% - I ran 10 hrs at GOTV and it was still around 60% power at the end (mostly with Phantom on).
If you grab them at the right time on ebay you can get a new PP 120 for $50 and a new PP 160 for $100. To my knowledge only the 120 and 160's ar 16V - everything else from Electrovaya is 19V.
I just got the Tekkeon 3400 to use with my MR-1 since the MR-1 is a 5 V unit. It's alot bigger than I expected but very nice.
I have been using my PP 160 for over 5 years and it is still going on strong.
The 3400 is a 55Wh batt, the PP 160 is a 160 Wh batt.
