Failure Of Lithium Polymer Battery Pack
I retailer all my LiPo's in a steel software chest in numerous compartments so if one goes up in smoke it hopefully won't take them all. They are a complete waste of money for all however small packs IMO. You can decide up surplus ammo bins for less money they usually supply superior safety. Cheaper nonetheless are hollow concrete blocks or even ceramic/clay flower pots can work properly to if you don't mind the load & bulk.
Cement board may also be used to make customized RC LiPo battery storage containers. Balancing plugs/taps as I already mentioned, may have one more connector pin than the variety of cells within the pack. A Li-Po pack may also be balanced with a stand alone balancer after charging the pack by way of the main power plug. LiPo’s may be balanced with a stand alone balancer similar to a Blinky Balancer while the pack is being charged by way of the principle energy plug.
The solely method I could even get them to cost was to force voltage into them till they built up sufficient voltage potential that my LiPo charger would permit me to begin a normal LiPo cost cycle. On the opposite end of the 'abuse spectrum', when you over-discharge a smaller capacity LiPo battery down with very little current, it may be okay.
It's not uncommon for instance to see the inner resistance readings drop after a number of makes use of of a model new RC LiPo battery. RC LiPo batteries are pretty secure if the foundations are obeyed. They are basically as safe or harmful as you are; but that is not to say there can't be the odd weird pack/cell failure due to a shorted wire, cell, comparable.
There are individual hundreds being utilized to cells which might be discharging these individual cells barely to keep all of them on the same voltage (inside that 0.02 volt vary). One caveat to this I ought to point out are the brand new generation of 'high voltage' LiPo cells. There are a number of manufacturers which are producing LiPo cells that can handle as high as four.35 volts and maintain a 500 cycle life is possible. More and more people are contemplating this 4.15 termination voltage the 'candy spot' for both efficiency and cycle life for RC utilization. Most RC chargers don't offer you that capacity, but if yours does, you might want to consider it.
Again, it all comes down to how much heat is generated when it's being over-discharged. I've definitely accomplished it myself and more occasions than not, yes, the battery shall be broken. So much is determined by the quality of the battery, size/capacity of the battery, the way it was getting used when it got over discharged, and how lengthy it has sat in an over-discharged state. For actually aggressive flying, I feel nothing past 70% discharged is healthier for the pack. 60% if you really want to play it safe to get the maximum attainable life out of your LiPo packs.
