Battery Error after externally charging - Dual 18650

[A3dspellinghero]

Hey forum.
Not a day after building (and using) my mod, the device starts throwing up a "Check Battery" error, this happened after charging one of my batteries outside of the mod to get them up to the same voltage.
Device monitor is reading:

Cell 1: 0.00 V - 0.01 V
Cell 2: 4.64 V

In mod settings I am set to LiPo 2 cell, using the Watt hour calculator, with the soft cutoff set to the default 3.09.

This is not the first DNA 200 I have had this error on, all of which have had to be sent back to Evolv for RMA.

If anyone could shed some light on this error at all that would be swell.

Don't worry, jurdanas. I have searched around multiple threads about this issue. Just hoping I can get some advice directly.

Well there isn't enough information, like what the DNA thinks the pack voltage is at. But what it looks like to me is the balance wire between cell 1 and cell 2 isn't getting to the DNA. This is marked as pin 1 on the board.

Just checked the connection with a multi-meter and re soldered the connection to no avail. I do doubt that this is the problem though, as it was working fine for about a day and then stopped.

Here's my device monitor as requested.

Yes it still looks like it isn't reading pin 1, right next to the one labeled GND (balance connection). If you take your multimeter very carefully and read the GND and pin 1 on the DNA board, you should read cell 1 voltage. The DNA is saying it isn't there. If it is there, then the DNA board is defective. If it isn't, it is probably an open wire.

Looks like it's time for an RMA then. Thanks for your help!
