Jsonnett's Latest East Coast Build

[Sliman_O]

@Jsonnett

If i use samsung 30Q cells (15A, 3000mah), i could get 24000mah per pack at a rating on 120A

So you’ll be running your pack warm (80°C) :

@Jsonnett

Would I be pushing the 120A rating of these batteries with my flipsky 65150 setup? Is this a continuous rating or peak? Is this rating accurate or way exaggerated like the Turnigy batteries?

I’ am no battery expert but looked for the same answers for my pack.

120A (peak) means you’re pushing 6kw in your motor which if memory serves is the motor max power. Look here, metrApp from Ackermann using same motor :

I don’t know if you follow my build, therefore I post here also: log of today

Flipsky 100kv, 12s, gong L foil, FR prop.

I don’t think you’ll be pushing more than 100A peak battery current with this setup, so 2x 6S8P should be suitable for your needs. If you ever need to use more than 100A peak (peak means not continuous), then you’ll probably have to redo your calculations to draw around 10A per cell and stay under 60°C.

You might want to order from Nkon or Fogstar. Fogstar cells are shipped from UK and available with a discounted price for efoil.builders members :

Sounds like I am might want to skip the BMS. Just read a post about someones van catching on fire! I guess as long as you have a decent balance charger, than maybe relying on a BMS might be riskier than just being responsible during charging and not letting voltages drop too low.

After reading more, sounds like the samsung 30Q is the cell of choice. Anyone know if i will have any heat issues with these cells in 8P and close packed diagonally? My max battery current is set to 100A on my VESC.

Yeah, I think it’s a bit tricky to find a suitable BMS for our needs. I’ll be interested to know what Lift or Flite are using ? Anyone knows ?
30Q cells are the one used by Lift and by lots of dyer, not only in efoil. They are proven to be good quality cells.
Heat dissipation depends on your amp consumption. 100A continuous means you’ll be running your pack at around 70°C I guess, see curves I posted earlier. Thomas from @funboards.at is building kind of same packs for his electric paramotors, so no problem with this configuration I guess.
