NOPE !!!!
No, do not do this to ANY Lithium Ion or Lithium Polymer Battery !!!!
Running them completely flat will PERMANENTLY damage the cells inside, and in the case of Lithium Polymers, may lead to them exploding.
At a minimum it's a fire risk as the cells start to out-gas and puff up.
Find videos from Quadcopter pilots on youtube to sell how quickly a depleted LiPo will turn in to a big flamey problem that is nearly impossible to extinguish.

Originally posted by Kombivan The thing I learnt about batteries is to never let them go flat because if they go flat they loose their memory and never get a full charge again. I have been using that principle and I am still using some 20 year old batteries and they work excellant. Smart chargers also help a lot.
That's for Nickle Cadmium batteries, not the Lithium based batteries used now.
And even then, it's slightly backwards, in that NiCad's that were not fully discharged developed a 'memory' effect, where they would discharge normally until they hit that point, and then would behave as if depleted, rather then discharging properly.
Lithium based batteries do not develop the same sort of memory.
As for the life of the DLi-90 battery, I'm using the ones that came with my K-01's and K-5's without any issue, charged only on the OEM Charger.
I'd recommend to K-3-3 owners to get an OEM charger and use that in preference to charging in the camera.
