Multistar High Capacity 3S 4000mAh Multi-Rotor Lipo Pack

Although the flyers probably won't like this battery because it has a 10C discharge rating, it is absolutely perfect for my use. I have an elecgtric boat that pulls about 5 to 6 amps and I have two of these batteries in parallel, so I can get about 1 1/2 hours of operation from the two batteries. For my use, I love them (they replaced two sealed lead acid batteries and are much lighter). Probably not for the speedboat guys out there, but are perfect for my use. I'm thinking about a new boat using two motors, so I would definitely purchase two more of these LiPos.

Good battery - works right out of the box. Generic XT60 connector, but it fits fine. Only a 10C discharge rate though - be careful not to draw more than 40A from this battery.

I ordered two of these after reading one reviewer's comment about a 25 minute run time. I did not get close to that time with either battery. My average run time (with a Phantom FC-40) from battery connect till rapid flashing red light was 13-14 minutes. I ran each battery on a full charge, twice. My four (original) 2200mAh batteries only average 8-9 minutes (each) using the same timing criteria, so I guess I should be happy with the extra 5 minutes. I'm not...I was looking for more. In addition, installing the Multistar required significant modification to the battery compartment, including a Velcro strap attachment to hold the door closed. It is big and adds significant drag weight to the Quad (8.8oz vs 6.0oz for the 2200), which I'm sure accounts for the short 5 minutes of additional flight time over the 2200. The "Product Description" boasts, "...increasing flight times for your multi-rotor aircraft without the penalty of added weight". All I can say is the author of this description must be thinking about some other battery, because an additional 2.8oz in Phantom FC-40 terms is definitely added weight.

Arrived 9/21. Using a BC20-4, charged them at 3A until flashing red/green (aprox 80%) then @ 1A until solid green 12.5 vdc , w/cells balanced to 4.2vdc +/- .03 vdc. Mounted to a dual battery plate on an Original Phantom..original phantom props, no gyro, no GoProTotal BATTERY weight was now 17.75 oz with 8000 mah capacity. Original battery weight and capacity is 6.1 oz and 2200 mah. SURPRISINGLY she leaped into the air. Fixed hover, 4' to 6' with absolute minimal maneuvering to maintain over a static marker point 16 min 20 seconds. vs 5 min 35 sec (2200 batt).More testing today to confirm results. Landing time was determined when continuous flashing red was timed to 20 seconds.Landed. 11.3 vdc, cells @ 3.79 +/- .02 vdc Battery surface temps same as unused Turnigy sitting nearby waiting for it's flight. IR temp gun confirmed. One added PLUS although somewhat less responsive to the controls that also means wind TOO!Additonal testing. 1A charge seem to be stretching it's legs with 18 + and 20+ same hover conditions...but warmer ambient temperature.

Great Battery, I bought this for my dji f450 with the e310 propulsion series and it works great. I also bought a multistar 3s 1300 mah battery and use that one for a backup, This holds lots of power and gives me around 15 minutes of hover time without a gimbal and camera.

Not too bad of a battery, ran it pretty low down to 2.10v on one cell, backed it off to .1 amp charge after a total discharge to 2.10 on all three cells at .1a, did a balance recharge at .1a for what seemed like a day, and cycled the above one more time, been punishing it since at 80% drain, balance charge at 1.0a and good to go 4.20 across the board, one cell does drop to 4.18 after a few secinds , but holds steady. Not a power punching pack and geared more for longevity and AV work.

no comments at this time but thanks hobbyking

Great battery, got up to 22 minutes of flight time on a lightweight F330 quadcopter running 2212 1000kv motors with 7x3.8 props. With 9x4.7 props, 16:30 minutes.
