Okay. I’m about to start building a new jet board (not foiling!), and hope that some people here can point me in the wright direction with new batteries.
At this moment I am using six 6S 4500 mAh Zippy compact LiPo’s (3 in parallel for jet motor one and 3 in parallel for jet motor two). The Zippy’s are rated 40C
The LiPo alarm triggers after about 15 minutes of having fun, and the LiPo’s do feel warm (not hot!)
Not really relevant, but the motors do 13890 rpm (according to my RPM meter).
This is pretty close to what I’ve calculated: 6S (22.4 volt) 13440 RPM (22.4*600=13440)
Today I had a Watt meter between one of the LiPo’s and I got the following max data from it:
- 3.736 Ah (Amp Hours)
- 78.1 Wh (Watt Hours)
- 36.03 Ap (Peak Amps)
- 20.80 Vm (Voltage Minimum)
- 842.6 Wp (Peak Watts)
I’m going to build a new board, and I’m going to use the same jet box (motors and jets).
The plan is to build the new board around the battery box… So basically I have more than enough space for batteries.
Now… What should I go for? Will 18650 cells be an option as the continuous discharge rate (C rating) is 40 for the LiPo’s I’m using now. Can 18650 cells handel this?
Or… Just stay with the heavier and more dangerous LiPo’s, and buy some more…
Looking forward to what you guys think.
