ROAR to change lipo voltage to 4.20 and 8.40
#46
Do you want me too? I have no problem with that
I have NO problem with that either.....I run a booster!
It is however a lipo and will need teching now.
There should have never been a tolerance in the matter of safety in the first place.
BTW the rule hasn't worked over the past 3 years

A low-tech solution to getting the battery back down to 8.40 volts would be to attach some automotive light bulbs in parallel to a connector and plug the battery into it until the desired voltage is reached.
My charger is not the best (I've seen it go over .01-.02 or so on a 2S pack) so I'm going to go this route for events where they are checking.

Why in the world would ROAR have made the initial statement and allowance of .04 in the beginning AND change it NOW? If it was allowable in THE BEGINNING and racers are going BY THE RULES and getting their chargers upgraded TO THE RULES then why change it????? What has changed in the lipo battery that would make you change an existing rule? It certainly has not ruined ALL the batteries from 2009 has it because of the extra .04V? Must we all now dispose all of our 2009 lipos?

Seems to me that the rule got used and abused, so it went zero tolerance.
Now the maximum limit is set, people know what their max limit is.
Personally, if I wanted peace of mind for my own charger, it would be at 8.38 or 8.39v. A bit like running a car close to the weight limit...

To Chris's point earlier about RC being more receptive do we really need to be teching down to .04 volts and asking racers to buy $300 voltmeters? (I realize ROAR didn't say this, you did).
I guess my only beef is that DQs should be reserved for people intentionally cheating. I would guess most people going over on voltage are not doing it intentionally and the fix for it (run the motor a bit to get the voltage down) is an easy one.

Roar allows LiPo's - racers complain because they have to buy new chargers
Racers read the rules and complain because their chargers that they just bought don't charge to 8.44V.
Charger company's complain because now they have to rewrite their software to maximize the allowance knowing the entire time that 8.40V is the rule. But they still do it because racers demand it
Racers complain because they have to spend more money to send the chargers back to the company to get updated...sometimes twice if you run a GFX.
Sounds like it's worked great

Doesn't matter if you got a charger upgraded or not. You are assuming the charger has that level of accuracy and most likely do not. If an accurate multimeter costs $300 and our chargers cost $150 do the math.

The comment about the $300 multimeter was sarcasm. Since returning to RC in VTA after a long time off, I now see why on-road is dying- the cost.

Have you ever been hit by the NiMh projectiles when they exploded?
Have you ever had $2000 worth of race equipment ruined because of a LiPo fire in your pit?
The punishment is light and a slap on the hand if you ask me?
It's a safety thing dude

I wonder if people were charging their batteries to 8.45 volts so they could back it back down the the absolute maximum of 8.44. Maybe that is why there is the rule change. Now people will target 8.41 so they can back it down to the absolute limit of 8.40.
