In electronics, voltages are usually measured relative to known ground rail, GND is quite obvious in this design and pictures. People can then calculate differences on their own if needed. Again, please append your question with a table of voltage on every pin: PIN1 = ???V, PIN2 = ???V, etc. | |
| Jun 3 at 0:10 | comment | added | Panamanian | Ok @Ale..chenski I measured all 6 pins while connected to the USB charger, volts result are in the new picture updated. | |

| Jun 2 at 20:09 | comment | added | Ale..chenski | You've been already asked, "Please provide voltage measurements (since you have a DMM) on each pin of the IC when Type-C charging cable is plugged in.". Each pin please. If you want to understand, get the data first. | |
| Jun 2 at 4:50 | comment | added | Panamanian | Yes, I said so. Besides, today i noticed something that "could" be the reason. The stock cell that it came with (low discharge cell) (drained about 3 ~ 4amp) measured at the motor start, the one i replaced, (high discharge cell) when i measured the engine it draws from 10 to 12 amps and then stays at 8 amp. Could it be the reason of a damaged IC? I know, i know the whole thing cost about 4 dollars but I 'm just trying to understand how things work and how things could get destroyed. If you guys can confirm that MIGHT be the reason, maybe i should have added a resistor (but dunno where). =) | |
| May 31 at 3:58 | comment | added | Ale..chenski | Ok, after deeper reading, do you mean that the device was working fine for 2 months after you replaced the cell, and only then it failed? | |
| May 26 at 16:30 | comment | added | jsotola | have you verified the power supply fitness? | |
| May 26 at 15:25 | comment | added | Ale..chenski | Q3: How do you know that it is not charging? Please provide voltage measurements (since you have a DMM) on each pin of the IC when Type-C charging cable is plugged in. | |
| May 26 at 15:02 | comment | added | Ale..chenski | Q1: does the motor work? Q2: When charger is connected, is there the 5V on connector pins? | |

| May 26 at 7:15 | comment | added | Panamanian | Yes i 'm awared of that, but I doubt it should have something with the issue. | |
| May 26 at 7:12 | comment | added | StarCat | Did you solder wires to the replacement battery (instead of spot welding them)? You might have shortened its lifespan considerably if you did. | |
