just do the math perhaps? 4 e.g. u got a 2.5ohm bulb that works on 2A, so the voltage would be 5v and boom u got the watts. 10W.

got a blown power ctrl ic? that tiny black square with 4pins on each side. i once had this symtom and fixed it with a same ic. the reason y i know where the problem is was because i was testing it without casing at the very moment so that ic just failed with a terrible red flame flash. it was just literally burnt

well i now that quite well. uv got a disconnection on one of the balancer wire. or broken wire lets say.

Well I totally agree.... What kinda tiny cells can be fitted inside that poor space... But I am always working with lipo so sorry about the lack of exp with li-ion and ur words were really out of my knowledge. Is Li-ion really that tough? No offense, just pure curiosity:)

Well I must say the only way to push this chip to the limit is to Craft your own mod. Just like this GIANT mod featured with a MASSIVE 4900mAh 11.1V (54.49Wh) Li-po power set. But I just didn't notice the size and weight it's gonna be untill I put the battery set inside........ and all of a sudden I was like, is it such a waste of this massive power storage? so I bought a 12v to 5v USB chip and got this done: a little bit flaw there but that doesn't matter. SO i got this shit Aluminum casing with hand drilled-filed holes, carbon skin and a little bit rainbow deco. I call it SA250W Carbon Deluxe also can be used as an emergency power supply~~~~~(no one cares but my phone with a poor battery)

Well, I've recently made a DIY mod all from raw materials but the chip set, and the battery set I am currently using is a 4900mah 11.1V Li-po (54Wh) set. The maximum current output turns out to be 100 amps without overheating, as the short test has shown. However my very first try was 3 18650, as same as your mod, witch turns out to be having the same issue. SO modify your mod and replace that 18650s with Li-po. 'Cause tuning the cut-off voltage down to 2.7v is actually killing your power supply. Not a native speaker, sorry about the terrible english
