Definitely need to make sure the meter is reading correctly.
If everyone's battery is reading high, it should raise a red flag

Is competition mode (plus charge)? That's the only mode on my charger that has a on/off function.

Tech Adept
Turn on your car and yank the throttle until you meet the rules. However, at some ROAR races, they may DQ you if you are over voltage when you come to the tech table. What I suggest is to have your own volt meter, and "calibrate" it to what the official meter reads. For example, if the official meter reads your pack at 8.42 volts, but your meter reads 8.40 volts, you better make sure before you go to tech your meter reads 8.38 volts (0.02v "offset" from the official meter).

Well I turned the Plus Charge mode off and my batteries came off the charger at 8.4V. I don't understand why they must be at 8.4V and no higher, 8.41V DQ'd.

If you overcharge lipo batteries too much they can catch on fire and burn down your whole village. The rule is for safety. ROAR's rule is 4.20/8.40v, most others still use 4.22/8.44v. Most agree that either of those limits are well within safety concerns. Is a disqualification neccessary for .1v? Most people think not

most GFX35 charge to 8.44 and 4.22 so if you run with that charger you got to watch out. I have a LRP pulsar 3 and you can adjust that. I saw sean cochran changing his at the IIC in 2009 so he was setting so that when he went to tech that he had it on the button. I know some of the cheaper ones don't have the greatest voltage control. I have seen them be all over the range. if your serious about running roar races then you probably need to get one that allows adjustment just incase you show up to a roar race that has a volt meter that's off. would be nice if roar did post a list of chargers that are SUGGESTED for roar racing. might be a selling point for a charger company.

Having been a past "victim" of the overcharging craze with NIMH packs, I say that ROAR had very good reason for taking a safe stance with lipos when they made their original call on maximum allowable voltages for events.
Besides OD (and at the really big events), I rarely see anyone charging their packs in an approved lipo sack. All the more reason for ROAR to be more so on the safe side.
And Bubblehead only having fifty-some posts on RCTech also gives me reason for additional concern. He may well be a newbie and likely should not be pushing lipo charging limits with such limited experience. BH should otherwise be working on his driving skills to obtain optimum results.

He is new to lipo and trying to figure everything out. Since we don't normally tech for battery voltage (or anything else for that matter 
) he had questions about voltage and charger abilities/defects.

Looks like you just nominated yourself to be BH's lipo coach...LOL
And I do like your reference to OD in your signature.
