Default Speedo and receiver with high voltage = ?

i have just brought a 6 pack of ib4200wc cells, and was looking at the voltage on them which was 1.312, 1.309, 1.310, 1.308, 1.315, 1.311, all together that equals around 7.8v. when charged the voltage will properly go up to around 8.5/6. but that is no good for my mrt as the highest voltage is 8.4.

will it reck my speedo be destroyed if i put the pack in?

The speedo's are rated using the nominal voltage of the pack which assumes 1.2v per cell.
Therefore the 6 cell pack has a nominal voltage of 7.2v even though it will charge to around 8.5v.
The 8.4V rating is for a 7 cell pack.

Your 42's will be ok on this speedi

A few people at the my club have packs with similar voltages, but they are usually matched at 30A, not 35A like most others.
Also depends on the cut-off voltasges used etc which vary from matcher to matcher.

5 minute actual run time rating. I had some ready real time with some good #'s, but those babies are nuclear. I'd like to know who matched them to.

im pretty sure he's talking about MEASURED voltage, not matched average voltage.

I have raced against a couple drivers who's cells have those figures, mine are more like 1.23 etc but I can beat them.

I've just looked at a couple of Demon packs I have and they are also 1.30 etc.

Demon are good for the price but they aren't any better than any others, and I'm sure they are matched at 30A.
