722 4400 mah battery life
« on: August 11, 2006, 07:44:40 AM »
The one that came with my 722. Never used it. What kind of life can I expect out of this with phantom on?

I'd guess ~4 hours if you keep the backlight off.
Out of the game … for now?

Thanks. I'm getting ready for one day of GOTV and should have it covered with 2 7000's and 1 4400 I would think.

i used the stock battery for about 3.25 hours, p48, meters and backlight off, and the battery meter indicated it still had some life in it, so I would guess that 4hrs or so is about right, however i have noticed that they seem to not run quite as long in the heat.

when is the festival? i have some extra High-Cap batteries I can send you to use if there's enough time to get them to you, if you think you'd need them

Not till the 19th. Thanks for the offer, however I think I'll be good with what I have, which should be good for at least 14-15 hours of record time. Plus I'll have recharge capabilities. :)

ok, wasn't sure if you'd be able to recharge, you should be more than fine with that for a day's use then!

as a rule of thumb, i get about 1 hour per 1000mah w/ phantom on, so i can get about 4.5 hrs out of the stock 4600mah one

FWIW tho, mojan at SS told me those start to go bad if not cycled immediately once its in your hands, thats why SS doesnt even have 722/744 batteries onsite, they order them from their source so they dont sit on the shelf and go bad, i bought a cheapie 6000mah one off of ebay and it would never reach full capacity, i get half of what i should out of it
