  • Looking for smaller 5S 5000 mah Lipo packs. Any ideas?

    I recently installed a Torcman into my H Models 7.6m Quintus. I am in the process of now adding the batteries for the motor (going to run 2x 5S 5000 mah packs) and also need to squeeze in an 80 amp speed control and 2 receiver packs, and lastly I need to add a tow release somewhere at the floor of the cockpit as far forward as possible. It is a big model but I want to keep my cockpit seat pan and my Axel Must look scale too right? I have some Turnigy 5s 5000 mah packs that I have owned for a while now and just wondering with the advancing battery technology, are there some smaller packs out there that would still allow me to run dual 5s 5000 man packs? Any space I can save, the better.

    Ideas?

    If you are in a real estate squeeze, perhaps 4000 mAh is not too awful a comprise? I have also seen a couple 3s x3 packs setups to make a tight space fit, but you'd lose 3.7V.

    While not the same animal, I went with two 4000s 100C in my EMS Quintus as 5000 was too tall, 120A ESC to the side, hid the tow release below the motor all resulting in Axel and his seat pan fitting perfectly. My receiver packs are alongside the retract on either side. My EMS Arcus has 4s x3 to make a seat pan fit in a 12S setup.

    I'm happy with the FES battery consumption yielding 4 good climbs. Below

      i find the new smart packs from hh to be very good and i use the 50c ones in edf jets with plenty of power and cool running packs. the size and weight on the 50c ones are similar to many 30c packs and fit where most do not.........might even find the 4000ma ones even better in same 50c packs.......

        Would these work? I've been using this line of batteries for about 7 years now, only had one issue with puffing on a 5000 mah 3 cell that I left charged for a few months. Not always the cheapest but one of my go to batteries after roaring top (for really good packs), or HRB packs from Amazon.

          Guys,

          Thanks for the responses. I was able to do some puzzle solving in the fuse and I think I may be able to make my 5000mah packs work out. I will move my receiver packs towards the CG and they should all fit (fingers crossed). With this bird set up with GPS, I was looking to ideally climb out to the 500m altitude to enter the GPS course so I wanted as much battery reserves as possible.

          Thanks again for for all the good information.
