Wismec RX200 cell volatges problem

[Daazzer]

FW - 1.08
HW - 1.04

All new Sony VTC5, nitecore D4 reads 4.2 for every cell, voltmeter - 4.13. Wismec says that "its normal" but when I ask them that its safe, they ordered me to write e-mail. Guess what? Still no response from them.

What should I do with it?

not sure, logic would say if your charger and a volt meter agree then that's the true voltage of your batteries but don't know if them being that far off from one another is a problem.

0.04V has been the biggest gape I've seen in the week I've had mine
HW 1.0
FW 1.08

Sell it and buy a sx mini m or ml class

I Googled and found this, along with a few more hits. Apparently what you're seeing happens with some of these mods.

I would use the mod but take out the batteries and check actual voltages as the batteries run down, specially when close to empty. IMO this is about not letting battery voltages go too low. If I were happy with the final voltages of all the batts, I wouldn't worry about it.

3.68/3.65/3.65

Looking better when cells run down, on voltmeter they are all on 3.64. Only when fully charged there is a big diffrence. Im using it for a week.

I really don't know if the slight lack of balance you're seeing is an issue, but for comparison I can tell you that when charging my Efusion DNA200 they stay perfectly balanced.

The biggest margin I've observed is 0.01v for a few seconds as one cell catches up with the other two.

This is of course on board charging of a 3 cell Lipo, so not like for like.

Then the charger is the culprit...overcharging, undercharging, etc and/or even just the battery won't hold the magic number of "4.2 volts"

I don't think so.

It's always the same Voltage on every cell every time when I checked it on voltmeter. Probably the "rx200's voltmeter" cant read it corretly, on fully charged is so much diffrence and when its runing down, cells start to be more balanced(only on "rx's voltmeter", when i put out cells and check it, they are always on the same level)

Hmm, forgive my not knowing, but what to press to get that on screen?

Turn off the device then hold fire button + down button for 5 secs.

Got it, thanks

What cells you use? And what is firmware and hardware on your device?

These threads are ridiculous. If you knew every point in your circuit where there was vdrop you would go mental. .02 battery differential would be the least of your worries.

.02 isnt almost 0.2

Also remember, new batteries have a break-in period. They will take a charge and discharge better as well give you a longer runtime over time.

You get my point though?
