Multistar 5200 batts

Posted by Jeff Colhoun on February 25, 2015 at 10:45pm

I picked up a few of these Multistar 5200 batteries.  Had an incident with the battery that came with my plus and lets just say im lucky i used a lipo bag.  

What are peoples experiences with these?  Im getting about 9 minutes with a gimbal, fatshark vtx, minimosd and fatshark camera.  Does anyone have any experience with both that can confirm this is normal or if these batteries are just crap?  Im getting about .7 to.9v in sag.

Im basically trying to determine whether a 3dr battery will add a significant increase in flight time.

Im overall unimpressed with this thing.  I ditched the self tightening props for 10x47s because of the power issue and its still a bit of a hog.  I needed something cheaper than another discovery pro for travel that didnt say DJI on the side and im starting to wish it did...

    Using 3DR batteries I've gotten 11+ minute flight times on a few occasions in 0 to 10 degree Fahrenheit temperatures with a DYS 3 axis (I forget the weight, but it's more than tarot 2D). I assume it will be better in spring, summer, fall.

    Based on your post, I guess I should start using the LiPo bag. I used it at first, but lately I've been lazy about it. Overconfident I guess.

      Jeff - What motors did you end up buying?

      I mean, Mark

    These batteries are utter crap. I bought four to test them for possible future use and the rubbish bin is the only place for them. I'm estimating their true usable capacity at around 2.5 Ah.

      Maybe that's why im having to land at 2500mah. I assumed the current sensor was wrong because i had to go in and mess with the voltage to make it accurate.

      You had a similar experience?
    • Hans Miller > Jeff Colhoun February 26, 2015 at 2:07am

      Absolutely.

    The good news is that your Plus did not fall out of the sky.

    Did you get any warning signs like, hot battery or swelling?

    How many charge cycles before the incident?

    • Jeff Colhoun > Dan McKenna February 25, 2015 at 11:03pm
      After the first cycle. Took it to 50%. Charging at 1amp my charger started beeping telling me im fvcked and i grabbed the bag and it was toasty. Tossed it in the swimming pool.

      I ordered the multistars when i bought the iris. Dont get me wrong, it feels locked in and nothing beats bluetooth droidplAnner in the field but the flight time and power issues are really a disappointment.
