DNA 250C no current from USB

[Dodecaphonix]

I have two identical Lost Vape Project Sub-Ohm Triade DNA 250C devices. One of them is having charging issues.

I've hooked the malfunctioning device up to the Device Monitor and here is what I've observed:

• it reads a consistent voltage from the usb power supply
• at about 10 second intervals it will read usb current and then quickly snap back to zero current

I've designed a theme where I can monitor these values from the device UI and this behavior is seen on all chargers that I hook it to.
 

Things that I've already attempted in order to resolve the issue:

• different sets of batteries
• high amperage USB chargers
• low amperage USB chargers
• updating firmware
• verify that identical, functioning device behaves properly in all above tests

Hmm. If you go into Tools->Serial Terminal, try the command X=READ BMS. That will clear out whatever battery-management errors it may have had in the past. Wait a while and send that same command again. What does it respond with?

Thanks for the help! Here are my terminal commands and responses. Commands were run 5-10 apart from each other. I've added "in:" "out:" for clarity, but actual terminal commands were X=READ BMS as instructed. What should I try next?

in: X=READ BMS
out: X=24
in: X=READ BMS
out: X=24
