I've seen people state that lipos are only good for about 100cycles, what is liable to happen to them after that?

I`ve been told that lipo`s swell up if the current drawn is more than the cell pack gives. I`ve had a few get warm that way. and since bought higher rated cells. No probs after that

they loose performance

bear in mind 100 cycles is 100 full to empty, or empty to full as one cycle so if u top up 50% each charge ur should get 200 cycles

All batteries carry the same risk, but not the same danger. All LiPo drive batteries should be stored and charged in a sack, as they have more stored energy than a small receiver pack, 'phone battery, etc.

And while we're on the subject of the ambulance chasers, and no-win-no-fee, they'll have got lots of useful information about how responsible RC people are(n't) from this thread. Everything you say these days comes back to haunt you, especially if you say it on line.

Yep, i like to charge mine at 10amps and repeak them at least 3 times before my race, you cant beat the fizzing and popping sound they make.

I hav ebeen following and reading this thread unfortunally the time has come to speak out about batteries and the safety;

All batteries carry a safety issue with them the same as you crossing the road in the same place everyday;

All it need is 1 stupid mistake and that is it the accident is going to happen

3 years ago i was working on a team members car when there receive pack completley exploded and this not only took my sight but severley burnt my face to;

After weeks of hospitlized and numerous operations i can carry on with my every day life and still love what i enjoy and thats racing even with 75% sight in right eye 45% in left eye with diffucult complications;

What i am saying is whether it is nimhs ni cads or lipos you as the right full owner must treat and look after these with respect if you are going mis abuse them then you are asking for trouble;

Please enusre you discharge and charge on recommended amps use lipo sagfety bag if using lipos and just be sensible we all know the rules and charging limits so ask yourself this

WHY DO THE OPPOSITE TO WHAT IT TELLS YOU TO DO;

As i can assure you the team that was me the evening of the accident will tell you the do;s and dont;s as they would never ever want to see any 1 go through what i did

any cell is dangerous if mistreated, if lipo was so dangerous would we be using it??

have to say this though, ALWAYS balance charge, you are protecting yourself and the pack by doing it.

i shorted, overcharged and shot a dying lipo cell and it did little more than smoke, they will catch fire, but it aint easy, the cell needs to be well charged and either greatly overheated or punctured. nicad will also explode and catch fire, from personal experience when a charger failed to cut off back in the good old days.... nimh cell went up at the club two weeks ago. in short anything that provides energy and gets abused is dangerous. treat your cells like a can of petrol!!
