Because there is a 10-15 minute walk from car park to our flying site
I bought 4 lipo batteries for my ENobler, only charge at home and this
has worked out well up to now. I re-read the storage instructions recently
and I realised that sometimes I bring the batteries , charged, to the field
and for one reason or another was unable to fly, high winds, rain, road
closures etc. The batteries then remained fully charged until the next
opportunity arose and so on, at one stage this turned into a 2 month wait
so now I use a 'Store' setting on my charger to discharge them, I wondered
how long is safe to keep them fully charged but unused, only topping up to
100% say the day before I fly ?  Is this a common problem with Lipos ?
