Thank You again. It seems that i must check min resistance limit on my own - but thats no problem. Now its time for little waiting - I'm going to perform further tests, when my ordered equipment arrive. Want to be 100% sure, that I'm not going to slowly destroy anyone battery by suggesting new method...

Early test were successful - was able to hotswap battery in field without any thing connected to USB port (in fact, second test proved that hotswap is possible also during hostmode), without disabling BME, with WIFI enabled downloading file at 10 Mbit/s + cellular 3G connection enabled and browsing pages, with brightness set to full. So, as i presume, there won't be need to disable anything in real life situation. Stay tuned.
