It depends on how they design the circuitry that connects everything (mosfet, resistors, logic circuits, etc.)... So it's hard to deal with generalities and override a specific model's recommendations. May be born of experience too.

Shorter answer: electronic power limits/heat dissipation.

General rule is to go with the manufacturer's recommendations. Of course, there are always people that will "push the limits".

I assume you mean < 2.0 ohms LR. Well, you're exceeding the manufacturer's recommended wattage use... so... anything?

Could work. Could Fry. Could sorta-fry, (??? Maybe even give it trouble recharging ????... that same board holds the recharge logic.. prolly a different path, but who knows!). May even depend on how fast you vape the lr306 on it and how much heat builds up inside (on the circuits).

If I was tempting fate, I'd recharge the thing in a safe area in a glass bowl so if it fried/vented I wouldn't have to redecorate the entire kitchen/house. lol. Also, it may just give out. IDK. Some have been know to "fail on".. but I don't really know anything about that specific model.

I've been temped to try LR stuff on a standard 510 (180 mAh) since that little battery can't put out much amps... and probably won't fry the mosfet (but will stress the battery). Of course, I'd do it as an experiment and only vape it one hit per minute or something to see what happened. I probably shouldn't mention that, but I did!

The thing is... with small battery stuff... the LR drains them so fast as to make it kind of a "shoot yourself in the foot" type of thing. Not only can it stress the battery, but it will cause more frequent recharging and thus fail sooner. So meh.

Basically, due to that previous paragraph, and the manufacturer's recommendations, I can't recommend it.

450mah per hour is a rating given by the manufacturer to give you an idea of the battery capacity. At a little less than 1/2 amp (500ma) draw, you can use it continuously for an hour. That would be a light bulb that drew 420ma of power.

A 1.5 ohm atty at 3.7v will draw 2.46 amps of current. Granted, you do that intermittently and not continuously, but it's a high drain load that requires a big battery. People do it all the time on an eGo 650mah battery.

A 2 ohm atty at 3.7v draws 1.85 amps. By contrast, a 3 ohm atty at 3.7v draws 1.23 amps. You can draw more than the design current rating for short periods. We typically draw 2 amps or more using an atty that produces 8 watts, which is the average wattage consumed by using a 2 ohm atty at 4 volts.

Yes, you can do it. It's all dependent on whether the electronics (the MOSFET) inside the ecig battery can take it day in and day out. If it fails, I wouldn't do it again. Sorry, but that's my honest opinion.

You'd be better off with a 1100mah eGo or Riva battery than the 510 battery with a LR 306. batteries are consumable items and need replacement periodically. Try it and see. You will charge more often, but you are more likely not to get the full voltage from that battery that you would from a more robust one, like the 1100mah eGo or Riva. The vapor and taste may not be what you expected. When you overload a battery, the voltage drop can be severe.
