Hello to all --- Im curious about battery storage during long term ( a few months ) bad weather when I cant fly.
Can I just let the batteries for my MA2 discharge completely until I can fly again or, do I have to perodically charge them so they never go completly dead ?
Thanks for any input.

Hi!
You might be better off posting your question in the 'products' section of this forum.
That is way more active.

Best to keep them around 50% and check them every couple of weeks.  But you should still be able to fly during the winter in the UK.

Thanks for that info DAFlys, I will do just that.  Im just worried about when it drops to  0*c  or a few degrees lower. I would think that windchill at or below 0 might be too cold for the motors when flying at or around 20mph. Not sure though, just being cautious.
Cheers

Youre good to fly down to -10c.  If you keep the battery warmer before you start people have flown in lower temps than that.

Store them at room temperature and fully recharge them to 100% then let them auto discharge to 60% if not being flown at least once every three months - don't just leave them for months on end or you may find that they won't recharge

I dont think I will be flying in temps like that but its good to know to keep the batteries warmer before you do. Thanks again DAFlys.

I usually just keep them in my pockets to keep a bit of warmth in them.  same as I would do with my spare camera batteries,  although the canon lipos I use have been fantastic in the cold.

1.If you do not use the battery for more than 10 days, please discharge the battery to 40-65% of its capacity for storage to prolong its service life.
2.Do not store the battery for a long time after it has been completely discharged, to avoid the battery entering into an over-discharge state, which may damage the battery cell and make it unusable.
3.If you need to store the battery for a long time, you should take it out of the aircraft.

Same here mate - saves having to hover for minutes before flying out
