Steve.W Posted October 13, 2021 Report Share Posted October 13, 2021 Hi, I have three Odin 250C's and all three have shown "check batts" and not fired. I have tried different batteries, some new and some older ones too. I only bought the newest mod last week and this does it too. Its strange how some batteries work in one 250C mod and not another. I have a Odin 75C and all of the batteries work in that. Any help would be greatly appreciated. Link to comment Share on other sites More sharing options...
Wayneo Posted October 13, 2021 Report Share Posted October 13, 2021 Post an escribe 'Device Monitor' screenshot of one of them not working, while plugged in. Not firing or anything. Link to comment Share on other sites More sharing options...

Wayneo Posted October 14, 2021 Report Share Posted October 14, 2021 Fantastic screenshot @Steve.W. On the left hand side, starting 6 itmes down, look at your 2 cell voltages. Cell 1 shows 4.440V. That's a problem. Disconnect the USB from your mod. Swap battery positions in your mod. Plug in and start escribe. Now look at cell voltages again in Device Monitor.. If that high voltage now appears as Cell 2. It's your battery at fault. How do/did you charge the batteries? Let us know. 1 Link to comment Share on other sites More sharing options...
Steve.W Posted October 14, 2021 Author Report Share Posted October 14, 2021 Thanks Wayneo, I had to pop out and forgot to unplug the mod from the usb. I have just got back and the mod fired straight away as it had obviously charged the batteries via usb. I only ever charge my batteries externally on a nitecore charger, so this would lead me to believe my charger is faulty. But only with some batteries. I always keep the batteries in pairs and never mix them. Cell 1 is reading 4.114 v and cell 2 is reading 4.291 v. Link to comment Share on other sites More sharing options...
Wayneo Posted October 14, 2021 Report Share Posted October 14, 2021 I take it your charger doesn't show cell voltages. Ideally, you could put each battery in your Odin 75C (if it shows battery % or voltage) and 10 puffs or so should bring the overcharged ones to lower than 4.20V (volts don't lie, and %'s usually don't understand anything over 4.20V)You're much safer charging in the mod which will bring them back into balance (slowly) until you clear up your charger issues. 2 Link to comment Share on other sites More sharing options...
