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.
