I have used this battery and charger twice. I have a spectrum 3s non g2 battery that I bought also that charges just fine. After running the g2 battery for the second time it now just blinks a green light on the S150 charger and will not increase charge. I’ve tried it on 5a, 3a, 1a and .5 a for 1 hour each and still on single flashing bar. Has anyone else had this issue? I don’t think it’s the charger because it chargers my other smart battery just fine.
