Yes, but they all had 8.4 batts. Now some will have 8.4 and some will have 8.7, thus the 'overcharge' range has been moved up from the 8.4's max overcharge to the 8.7's max overcharge.

Yes, unfortunately the over charging came along right after lipos were introduced.
Not anything new, battery voltage is simple to tech and should be checked at all races.
If they aren't checking most likely someone is over the limit.
This assumes there is enough grip for it to matter.

Yes, on 'old batts' people charged to 4.45, .25 above "normal" so now "normal" is 4.35 so people will charge to .25 above that, 4.6
can you see the difference between:
4.45/8.9v
and
4.6/9.2v
?????
That's my issue:they guys with the new HV batteries can cheat EVEN MORE than the guys with non HV batts
With only one voltage battery you assume cheating but the cheating all has about the same MAX.

The solution is simple. Drivers must come to technical inspection with an unplugged battery before they drive. TC will check the voltage and will detect overcharged batteries.
This has been a well known procedure but still you see people giving a lot of throttle before the voltage is checked, new rules say that may not be done anymore.

Then don't use the advice, speaking of throwing money out the window, wouldn't that be what someone is doing spending $150 on a HV battery to charge it a additional 0.15volts.
We live in a world where things can be pushed to save money, because we want more power! My 3.3ghz i7 CPU is overclocked to 4.8ghz, with additional voltage and cooling. All of this for the cost of nothing. Because I can, my choice.
I put in my 2¢ I charge all of my batteries to 8.7volts, or 4.35 with no adverse affects.
I tested this on a few puffed 6 year old Turnigy packs.
I de puffed them, popped a hole with a toothpick, put it in a press gasses came out, and I hot glued the hole. These batteries are like new again.
A few have over 100 cycles without puffing. Lipos are a hit or miss, and we abuse them already as it is.
If you get a 100 cycles on a $30-$50 battery and it dies, you just about got what you paid for.
If you're worried about charging a standard Lipo to 4.35v, then please do not try this.
I have a certified Trinity battery I do not overcharge they run over $200 a piece and I choose not to so I can get 200-300 cycles.

As for spending $200 on a Trinity 'Certified' pack, THAT'S a good way to waste money
