yes you are right. Lithium batteries dont have the memory effect which used to be in earlier tech's. So you can charge it anytime and discharge it anytime. Just dont go below 5% because battery heats up (due to quick charge) and lower the charge it faster will it put so it heats more .. more dust reducing battery life .. so anything above 10% is good for charging ... Sorry again for english .. (i used google translate to know what you wrote)
