Lipo HV Graphene
#1
What's the deal with this new battery type?
I heard:
- heavier than LiPo but
- more power/higher c-rate
- more capacity
- lower internal resistance
But what are the real negatives on this new battery type?
- Are they saver to charge?
- How many loading cycles until dead?
- Are they legal?
- Only a hype?

Graphenes are marketed as higher capacity in same size class due to the graphene being a thinner design. Ergo more mah in the same relative size. The cycle life is also supposed to be a bit longer when charged at 1c rates. Add lihv into the mix and it's a real capacity boost not to mention the extra punch and rpms it will produce. And for stock class guys it means all of this for lighter packs with a longer run time above 4.0 volts per cell. Plus from what I've seen at local tracks, the IR numbers can be a bit lower. Also a good advantage for stock racers as this produces a punchier, faster car for a little longer than regular lipo packs.
This is from personal use and close friends pitting with us at races. My experiences have been very positive including all of the above mentioned aspects, along with less heat in the pack under heavy discharges. Like a lot less heat when pulled to 3.5 volts per cell for stock racing. Less heat also helps increase the usable cycle life, less heat=less damage.
No hype as far as I'm concerned. The new packs when pushed hard in stock racing have an advantage even when charged to a legal 8.40 volts or 4.20 volts per cell. Which also helps increase its usable cycle life as you would only be using 80-90% of the packs actual abilities to provide power.
Hope this helps. Again I'm no engineer, this is just what I've seen and tested along with close friends.

I've been running the Protek 3600mah lcg lihv battery and the 6100mah lihv battery. All in my Associated buggy, truck, and 4wd. I only charge to 8.44v and get about 3200mah out of the 3600 battery and 5000 out of the bigger one. Running in the 17.5/13.5 classes I have had no run time issues. Using an icharger, I notice IR anywhere from 1.1-1.5 per cell.

+1. I'm running the new LRP 8000 graphene packs in a very heavy discharge application. (4s HW XR8 Plus with G2 2600kv motor - Serpent 977 Viper-e). Run time is fine and incredible punch when compared to my previous Intellect "standard" lipo packs. The LRP's come off the track noticably cooler than the Intellects did too. Very pleased so far!

Any updates on best LIHV Batteries? Protek's getting a bit expensive to buy multiples. How are the Fantom LIHV ones? How does the Turnigy Graphene's IR's compare as their about 40 percent less? In the market for some new batteries.. BTW if anyone wants to trade some proline primes for some LMK

I wouldn't say that graphene batteries are just a hype. Graphene and other advanced nano materials are used in many different products. Graphene in particular is amazing conductor and can with right application enhance properties of different electronic devices. Namely batteries are seeing very rapid development. You can find some interesting info on mstnano.com. Also expect that if now are batteries on par with each other, graphene should win the race in near future.
