Reuleaux DNA200

[Jwhelfer]

Was just wandering if anyone could give me some information. I have a reuleaux dna 200 and when go to power on it shows welcome.screen only if I'm holding fire button. Then if I keep pressing it it will show normal screen and check battery. While plugged into USB screen appears and shows no battery and no charging symbol. All this just happened when my batteries got low. It was out of the blue. No troubles before at all. Also including pics of diagnostics from escribe. Cell 1 is showing virtually 0 volts. I've tries different batteries and also checked ground. Any other suggestions or ideas?

Charge it up, all the way. Low battery power causes glitches, no matter what it's powering. If this isn't the problem, could be juice on the board, or batteries aren't "married".

[Jwhelfer]

I've tried several sets of fully charged batteries. Even a new set. Also checked to ground. No juice on board either. I took it apart to check and best of my knowledge I've seen no burnt or bad spoto on board. I'm puzzled. Thanks

Almost sounds like cell 1 is not getting a good connection to the battery sled either by a poor physical connection or a poor connection via the wiring of the sled.

[Jwhelfer]

Seems right. I'll double check the sled again tonight. Thank you very much. I'll get back with results.

[Jwhelfer]

I checked voltage and getting a little over 12 volts straight out of the battery sled.

are you getting correct readings from the balance wires going to the board? continuity across the fuse? correct voltage after fuse? i know wismec took a short cut and bridged the gnd and 3rd cell balance tap connections to the main -/+ with 0 ohm resistors to save on wiring. maybe make sure you have correctindividual cell readings at the tap. if you do have correct readings and there's no ejuice, burnt or missing components around that area of the board i would open a ticket with the vendor. then evolv if they do nothing.

[Jwhelfer]

What should the voltages across the balance wires be?

[BillW50]

Te black wire is ground (on one end) and the red wire (on the other end) is the total of all. Something between 9.0v to 12.60v.

Between the black wire and the one next to it should be cell 1. Next to that one and next to the red wire is cell two. Between one and two should just read cell 2 voltage. Now measure between that one and the red one and it should be cell 3. All cells should read nearly the same and probably between 3.0v to 4.20v. The exact labeling is like this:

Black = Ground
White = pin 1 (between ground and this reads cell 1)
White = pin 2 (between the first white [I think they are white or yellow] and the latter reads cell 2
Red = pin 3 Between pin 2 to red reads cell 3

If I just confused you, we will post a diagram.

[Jwhelfer]

A diagram would be very helpful.

The black triangular symbols are the case acting as a common ground, consider them connected to each other.

[Jwhelfer]

All those checked good. I did check continuity from positive into board to the ground of the board where the ground screwi should be and it's not closed. Should that be correct?

[VapingBad]

The ground pad, and output ground pad should be closed with the case, 510 -ve & lowest battery (top in the sketch) -ve. One of the screws for the battery bay provides the board ground, so if that is out for testing it would explain it.

[Jwhelfer]

I have the board out of casing.
