Hcigar vt75d acting weird

[erix222]

Hello , so after my last frustuation of finder 167w getting broken , i got a board replacement and everything worked fine , yeasterday i have got myself a brand new hcigar vt75d , and it was acting a bit wonkey, its a parallel device but when i put both batteries in sometimes it doenst even turn on i have to open battery doors and change position of the batteries , then it starts working but not as expected , after nearly full discharge i have noticed that battery life was awful , so i just took out one of the batteries to check their voltages seperately and here it goes again ... one of the batteries were 3% while another one was sitting on a full 4.18v , so i charged them and tried to swap batteries in places , the same problem occured... the funny thing is i can take out and put in the same batteries inside but they show different voltage almost everytime... could it be a bad wiring / soldering issue ? Tried to charge it on usb , one battery got charged to 93% while another was sitting on 9% ( right where it was discharged) Im really upset , any help would be apreciated , thank you....

P.S. All the photos were taken at the same time , i have just swapped batteries in places

EDIT just checked both batteries in pico 25 show 81 and 82 % while the dna at the moment shows 61% with both batteries inserted

Sounds like a bad connection on the battery sled...using Device Monitor in Escribe,  you should be able to figure out which side it is on...

Well i think both of sleds are wonky , will check volts with voltmeter , and search for mistakes in soldering. How can i check for the bad connection with device monitor ?

By checking the voltage in Device Monitor with batteries installed individually...

Oh one more thing. I can use a battery in both sides just fine , sometimes it just refuses to power up , then I just change position of the battery close the battery door and its up and running again , I was thinking maybe battery sleds has poor contact with the batteries themselves ? Im really lost... I will tell tommorow if the soldering or wiring had something to do with it. But if anyone has any ideas I would be glad to hear em out...

I’m having a similar issue with a Hcigar DNA166 dual 18650 mod. I should put it on Escribe and see what the device monitor says. When I put 2 fully charged batteries in it, it will power up but then shuts off immediately. All soldered connections look fine.

U have to check ur Escribe battery settings maybe it is set to 3x 18650 if not then contact evolv support , because it is a faulty chip , had the same issue with a finder dna 167  , my issue is a little bit different though

I have the same problem with my new vt75d.  Did you fix the problem?  I would appreciate it if you could tell me how you did it.

Had the same problem.

there are three pins at the bottom to fit in the battery, some batteries does not fit very well.

A sandpaper to  lower the pins and you are good to go with any battery.

Cheers

Can you tell me what pins you are talking about?

I'm sending you a couple of photos so you can tell me which ones should be sanded.

Thanks!
