I just started running lipo's in my race cars (Track just started letting us) but I have been flying with lipos for 3+ years.
Since I started the battery wars have been hot and heavy with new packs coming out with higher C ratings and lighter packs every 3-6 months.
I expect to see the same in car packs. I also expect to see companies lie about capacity and C ratings as they have been doing in the air packs.
I have been in this hobby for 25+ years and there has always been "battery wars", it won't end any time soon.
