Mod says one voltage, charger says another...

[Drewps5co0tt]

Hey,

I just bought the xtar VP2 (my first charger to support onscreen read outs.) When I check my voltage on my battery inside my ProVari (for instance just now it showed 3.4 volts) I pop it into my charger and the charger displays that the battery has a charge of 3.5 volts. Was kinda curious why the difference in readings? My batteries are AW IMR's 700mah from RTD Vapor

Thanks!

0.1 volt is pretty insignificant and it is possible that the Provari is reading it while under load, which will lower the reading. The charger itself should be delivering 4.2 volts to charge the battery, but it is not likely to read that until it is fully charged.

If you grabbed 10 different meters and shoved them into your wall outlets, you'd probably get ten different numbers. All would likely be close, but not exactly the same.

Also bear in mind battery voltage is not constant and takes a while to settle down. If you've just had a drag and you check your voltage straight afterwards, it will be lower than if you left it for an hour under no load and then checked it.
