ProTek RC 2S 100C Silicon Graphene HV LiPo Battery
#1

I was looking for any feedback on the ProTek Silicon Graphene lipos. I have not been able to find any reviews on these batteries but, i went ahead purchased two. Any feedback would be appreciated.
Thanks

So is it true that Graphine batteries are more prone to damage if they are under-volted compared to a traditional LiPo battery?

I wouldn't know as I do not attempt to drop my battery voltage that low lol. I think it's safe to say any lipo battery whether graphene or not, is going to be volatile if you mistreat them such as running them below their recommended voltage. Keep the voltage above 3.2v per cell and you should be fine. Going below that in my opinion is asking for trouble.

The Protek is good if you can get one that has matched cells. I've had four of them and two were good and two were bad. The bad ones each had one of the cells that wouldn't even get close to what I was trying to charge it to. So if I set the charger to 4.20 per cell, the bad cell would be like 4.17 and the other would be 4.20. The cells would never balance, even after many cycles on the icharger.

Were you able to race last weekend and what are your thoughts?

That's what I've found, maybe I just got bad ones

Andybellus,
Sorry for the delay. I was able to run my 17.5 sedan with my 8500 pack. A fellow racer let me use his Icharger 306. He balanced my pack and showed me that each cell was matched. I forgot what the internal resistance read? This being a new 8500 pack, I was expecting a little more punch and speed compared to an older Orca Infinite 6200 that I also run. I did notice that the ProTek had a little more acceleration but, that was about it. On my next practice day, I'm going to compare balance readings and lap times. I am still learning about lipos so feel free to chime in if I screwed up.
