Tolerable imbalance?

[Popeye]

 
I am a bit of a noob when it comes to lipos, what is a tolerable imbalance between cells please?

[Nick]

That is an acceptable imbalance as long as all the cells are fully charging to 4.2v when the mod finishes charging.

If the cells are out of balance to the point of concern the board will actually throw a message stating so.

Though that ok as numbers go, I would vape the pack down and see if the gab grew during run down.

Probably should have followed this up sooner. Turns out it was a bad battery. It fully charged to 4.2 per cell, but it was sagging massively under load. At full charge it wouldnt even fire at 50w on a 0.2 kanthal build.

When i plugged it in its because cell 2 was sagging to 3.1v, from full.

Swapped the battery and now my battery life has pretty much doubled and im using a lower capacity battery.

My battery is less imbalanced than that-but is giving me a battery error message. I think it is 100% the Li-Po though, as it arrived a 3.7 volts! So I had to use escribe battery recovery, but it still throws out the error message if left idle for half hour or I remove and reconnect the battery- but if I connect to Escribe it boots straight away so I can use it. 

I am trying a full USB recovery charge and also hard reset the device- Before I only used it for an hour or so, then finished on the usb port but the wall charger, I am hoping a full from near zero recovery charge will sort the issue, as gearbest are idiots, I described the problem in detail, and they then said could you please explain your problem in detail. 

I sent a similar message, tried to make it easier to understand, and showed them the error message. I do not expect them to replace it though and wont use gearbest again, but I got a fully made DNA 200 for the price the chip retails for in the UK, so even if I have to replace the Li-Po, it is still a fully made, great working unit for under £100, the cheapest in the UK are £180+.
