Looks like it sees the battery to me. Although it sees the voltages all wrong. Cell 1 reads 0v. I wouldn't keep the battery in it. As when one of mine was read that low, it drained that cell by 50% in a day. Without a meter, not much else you can do except to contact Evolv.

can you take pictures of the board, front and back? picture of your balance wires soldering. i want to see your soldering.

in escribe, under manufacturers settings you have 3 CELL and LITHIUM POLYMER selected and uploaded to your dna200?

test fuse for continuity with multi meter.

No good word [nono]
No good talk [nono]
I tried 3 18650 new sony VTC 4, and 3 LiPo 3S at 950mA, 1000mA and 1300mA, all new.
Becomes the same.
A lot of talk does not mean a lot to know [nono]

Yeh you dont say mate.. As well as obscuring the poped fuse with a bit of rag, You know youve burnt the charger out because of poor quality aparalall..

My test with multimeter battery connections:
GND + 1 = 0-200-0 ohm (bad)
GND + 2 = 0 ohm
GND + 3 = 0 ohm
1 + 2 = 0 ohm
2 + 3 = 0 ohm

I think presume that the battery management chip damaged, placed near the USB port.

I read a lot (many), I try to do, checking. I know what's electronics, soldering, fuse....
I write very little.
Before you post here I first check everything and then write post.

Please add what you have been using for a charger, is it the same charger that was used on both boards?



Yes.
SONY 850mA and from "7'-pad" 2100 mA.
They are used for 4 years, they are the good. They can load charge only norml or slower.
I dont push in 110/220V ;)
