Lipos : test, feedback, temp,


Well, 5,2Ah is like nothing (empty in 5-10mins), take at least 4 parallel. Then you get ~150A without a problem.
I got the 5,2Ah 4s Multistar for flying. ~10C/~45A hasn’t been a problem so far.


I hate black friday, it makes us buy too much stuff we dont need… Buuut there is a good deal on Lipos now :slight_smile:


Might not be that great offers after all :stuck_out_tongue:


The 5,2 6s is even cheaper now.
I made an excel sheet, price per Wh, it is still the best.


So I bought 4 pieces of 10Ah, 10C, 6S Multistar batteries. Two will be connected in series and those 2 wil go in paralel. I am putting the ESC separately in an aluminium housing. The battery box will be far forward and submerged in the board. I hope the temp will just be ok.


Is 10C going to be enough? My understanding was that we needed closer to 40C discharge and running in parallel won’t change the ability of the battery to deliver the amps, only the capacity.


10c means 10 times the capacity. So in this case 10 x 10amps = 100 amps per battery.
And yes, in parallel this can be accumulated, so 200 amps - on paper.

So maxmakers lipo pack can deliver around 200amps x 12 x 3.7V = 8880 watts. On paper.
Should be enough to get up on the foil.


That was my thinking. I am glad you confirmed it. 200€ is not that bad. I wouldn’t mind doubling it if everything works out and riding it is fun.


I think I can see where the confusion lies, related to the nomenclature.

The C rating DOES NOT change when run in parallel, consistent with what I initially believed. However, because it’s expressed as a cumulative sum of storage capacity (which I neglected to consider), which has doubled, in this case because it’s still 10C, it’s expressed at the 20ah, rather then the 10.

My concern was everything I’ve read says you need more 100At o get going. Based on this, you should be right. Hope this helps someone else.

(where’s the wiki??!)


You do not need more than 100A. We max out on about 70A.

And ride on 30-40A with ease. (Big foil)

40-50A on small foil.



But then you could run higher pitch or larger prop.
