I recently bought the Captain PD270 mod. I charged it via USB due to my charger not arriving as yet. last night I left it charging as usual and electricity had went and I didn't unplug it from charging, I left it plugged in even after current came back it was charging. Now this morning the batteries won't charge, and later this evening I plugged it back to charge and it did not move up from zero bars.. At one point I got a question mark on battery A an it went after a minute... and I left it for about 3 hours charging and still no charge can anyone help me please? It still powers on but wont fire cause the power is toooo low. Please anyone can you help. Thank you
