John Cook Posted August 16, 2007 Share Posted August 16, 2007 Hi there to you all! I have a question! I was working on my electric doing some adjustments. When I finished (the phone had gone upstairs) I turned off the Tx but I forgot to pull the master switch on the plane. The electricity from the battery was therefore continuing to flow to the on-board radio gear (and maybe a little residual to the motor ) The plane stayed this way for maybe three weeks or more(lousy weather we've been having down here lately)Net result I had one over-discharged battery (Hyperion Litestorm 11.1V 2500mAh 20C) With not too much optimism I put it back on my trusty FMA charger on less than 0.5 amps with balancing every five minutes. Well slowly the charge came back but only to 88% capacity. Question can I continue to use this battery accepting that I onl;y have 88%of its capacity (and therefore only 88% of its original flight duration) or is it time to recognise my losses and consign it to the dustbin? Appreciate some advice on this? Thanks John CP.S. Haven't heard back from you Allan. Appreciate a call. Thanks Quote Link to comment Share on other sites More sharing options...
thunderbolt2007 Posted January 12, 2009 Author Share Posted January 12, 2009 Hello John, I think if you are going to use that battery you may be asking for trouble, I know its a bit late but always turn the model off first then the transmitter. cheers.

Tim Mackey Posted January 12, 2009 Share Posted January 12, 2009 It wont be dangerous, so not sure what bryon means by "asking for trouble" - if its come back, albeit not 100% then I would use it....perhaps not in my £5000 pride and joy, but general hack use - yeh Quote Link to comment Share on other sites More sharing options...
thunderbolt2007 Posted January 13, 2009 Author Share Posted January 13, 2009 What I mean "asking for trouble " is that if you fly with a battery like 88% unless you run a test in the model on the ground, in the air you will not now if a cell or cells may break down in flight. check it out first.
