Graphene batteries...can they catch fire like LIPO's if punctured?

My fingers have healed BTW. lots of power in 10s dead short.

That is good to hear, It did look nasty.

Yes graphenes can catch fire. I might have one I can shoot or puncture to show you. Lone-wolf had a graphenes lipo fire not long ago

Mine too but I couldn't feel the end of my thumb for almost a week. Thinking back on it. I think I actually shorted 12s. No tell'n for sure what the hell I did. The arc welding like flash may have disabled a part of my brain.

Jay is dead on. Don't forget these suckers are capable of hurting us. No matter what brand, the C rating, or which generation. Treat them like they are dangerous because they are.

I just got back into rc this year. I was still running my old nimh at first.
I converted my old astroflight 110D charger with their new chip and bought graphene batteries. Wow do they pack a punch. Ive been charging them in a ammo box as I am nervous... But so far so good.

Hey TS I just found a h20 ufo mono bare unbuilt hull , that I bought many years backs. Do you still make hulls?

Holy crap. No,not anymore. Once everything went brushless we were all going too fast for plastic. I still have one left that I built super super light for N1 mono back in maybe 2006? Didn't even get paint. Flimsy POS. Raced it once at CAFE. Sitting ever since.

I never ran cheap packs when I got into the FE game and have been fortunate. I've pushed hi end packs to the limits of their existence at record trials and no fires. I did seriously over do it to a pair of 5S 4200mah packs once when I set the T hydro 1/3 mile oval record. Had a killer run and at the end of the 2 laps they said it didn't pick me up, I yelled go again and stayed out. Smashed the record on that run but when I un-taped the cowl it smelled really odd and some purplish stuff had oozed out in the battery area. Put the cell % checker on them and showed nothing. Pulled them out (they were VERY warm) and set them in some sand away from everyone and told all to avoid that area. Nothing happened and took them home, gave them a salt water bath for a few days and tossed them. As others have mentioned it seems the issues have been with "budget" packs for the most part.

It does seem light..

When I built my oval master offshore I put carbon rods in the strakes where I could fit them and added 1/8 plywood transom and inside the hull.
I still have the Om it has one of Andrew gilchrists lightning man neo 05 13/3 in it.
It's still runs light a bat out a hell on 2s lipo with rc hydros esc and x437/3 prop.
Can't wait to try that on 3S with an x435 .
