Re: LiPo storage and charging safety

Yes the puffy packs may get that way but there are usually reasons for that some being discharged too low and recharged too fast. Cheap chargers . Cheap batteries, as I usually try to go with midrange to the higher end batteries all depending what I use them for and the current drains expected. Also storage charge is highly recommended by all manufacturers but some owners do not. Read and follow the manufacturers recommendations but a lot do not and issues develop.
What I mean by cheaper batteries are the cheaper design and makeup not the dollars paid as that can vary for the exact same brand and capacity.
About lipo fires ; a couple of weeks ago one of the fellas had a very large (4.7m) glider crash due to elevator servo lockup and the fully charged lipo was torn at the bottom so the insides could be seen.... no fire , no smoke. Some manufacturers have improved the interior chemical makeup to minimise flame but there may still be some out there that may smolder-smoke.
Also buy the highest C discharge rating you can afford even though you do not need it for your application as that minimises the IR ( internal resistance) changes over time. Just my opinion but there will be those that will dispute with their own beliefs. Knowledge is gained by research rather than hearsay . Thanks for taking time to read.
