danie.e, what you say make sense.danie.e wrote:Maybe the time has arrived for a separate section where LiIon, LiFe, and LiPo batteries are discussed in depth - something like a knowledge database. This topic started with redundency and is currently about the failures of LIfe batteries and how to charge them etc.
So maybe we should try to reach concensus about the use of a single battery or more in a RC model. So the question here is, is the use of a single battery a "dangerous practise" or should people only be warned?
I would like to agree with Clive in that most RC accidents happen because of some electrical "mechanical" issue such as switches, bad solder joints, too thin wire used, etc. etc. Batteries are quite often mistreated by most RC pilots purely because of ignorance and yet, sometimes they last quite a long time before actual failure. Obviously there are the ones that fail when new, but that is the exception rather than the rule.
So here goes: In my opinion, the use of one battery is OK when the owner has done the trouble to gain the required knowledge how to maintain his batteries. In all other instances the best practise would be to use two packs each with its own switch.
I for one do not monitor my cells well enough. I do check before each flight and do balance charging time to time. One of the issues and I am guilty as well, we do not understand these different cells (LiFe/LiPo) well enough. The stores we buy from...........well some of the "clerks" also do not know what the proper way is. I have seen quite a number of topics regarding all sorts of battery packs, how to charge, how much to charge, it still do not make sense to me. Yes, I am one of those that think about the battery packs every time I put my 50 cc in the air, I pray and at the end of the day quite while I am still ahead. I would love to see proper SOP on these LiFe/LiPo cells, I would love to see the recommended brands.
In you last sentence, two packs. How would you do this?
