just wanted to let you guys know i ran the battery pack right down till it cut out and then charge it via my decent charger and the total mah isnt anywhere near the 13800mah stated.. i even ask tech support for them to verify that they were 13800mah and they did tell me it was true... its full charge from flat to full charge was only 2850mah not even a 5th stated. im not happy att all as i was using to power the gps speedo so i didnt have to purchase a big heavy battery as its a racing yacht....so im really not happy with this or hobby king... and to send it back its nearly 2/3rds the price and a whole heap of hassle so they have lost me as a customer...

I'm using this jump start pack as is as the flight pack on a 1.9kg H4 650 drawing 25A (270W) hovering, My first discharge took only 2.5ah, a far cry from 12.8... however, my second discharge took 2.95ah, so i hope that after 10 or so cycles I'll have more like 5ah. This battery discharges steadily from 12.6v (with a sag of around .8v @ 25a draw) but when you pass 10v (underload) the voltage drops like a stone, from 10v to 9.4v is 10 seconds (250mah). Basically, set your LVC to 10.4v, with second level @ 10v - from 10.4-10 you'll have 2min then 15 sec after second level protection cuts in. So far I don't think it's worth it as a flight pack, but I'll keep you all posted and let you know if the discharge capacity increases.
