I'm going to leave inspire1 for more than 1 year. I have discharged batteries to 0%....but is it good for the battery? It must be between 30% to 50%?  Is it same as phantom2 vision +?   Thanks

You can charge it to 100% if you wish, it will discharge itself to a safe level. Do not, however leave it discharged to 0%. Not good!

If you like, you can send it to me and I will look after it for you.

Please ensure that you follow the long term battery storage instructions that can be found in the Inspire 1 Intelligent Battery Safety Guidelines. It is never recommended to leave a battery a 0% for extended periods of time.

Rule of thumb is Lipos should be stored at 60% charge. If you are not flying for a year why not just sell those batts and purchase a new set when you return. Lipos sitting for long periods are never good. You might also come back to what a lot of people are getting and that is a fully dead and will not power on batt because the logic board constantly has a draw on it.

i learned this lesson the hard way.  i had 2xt47 and 2xt48 sitting for nine months.  they are now dead and even using lynn phan's restoration procedure didn't help.  they are dead.

How many cycles on the batts?

We do not recommend that batteries be left unattended for an extended period of time.  It can lead to an over discharge condition and as HermosaDrones stated a dead battery.  Do you have anyone that can recharge them ever 2-3 months.

Thank you everyone for answering this.  I already left for overseas. Damn I have discharged to 0% 3 of 2 batteries while waiting for the answer on this forum...  I knew automatic discharge but wondering what should be for very long strage.  I wish give it to someone look after or should have sold it. My family will be back after 3 months and I will ask for rechage it But I really hope it is still not dead after 3 months especially 0 % batteries!!!
