New battery's hv
 

Just looking through the shops and seeing a couple of hv 7.6 v lipo silicon grapheme , is anyone using these ? How are you finding them, is there really that much differance in performance ?

I have nosram 6400 2s to try Sunday but racing rules say can only charge to 8.40v not the 8.50v that batteries can take but if u not racing and using a good one u should see a little more speed 1-3mph
