Ions or Polymers for RX pack

[Grow Pattern]

Peter,
           I've got four years on the Li-ion packs. On my C-volt meters you start at about 8.4V and use about 0,2V per flight. I don't fly below 7.2V. This is using JR digitals all round.

What I like is that the charge rate is not fast or slow. It takes about 2 hours to charge a pack. You can charge between every flight if you want to. No memory problems. You can go for many, many days after a charge and it is still charged for a full day's flying.

After a days flying mine are all ready to go after an hour on the cigar lighter type 12v charger.

You can hurt or kill them if you drain the battery too low, but stopping at 7V will do the trick.

Regards.

Eric.

  Hi all,

   

  I have decided to switch to this lithium battery technology for my F3A models mainly for increased flight time.

   

  My typical flying day consists of 6-8 flights. I run digitals all round and I am currently using a 1500 Mah NiCad pack.

   

  I want to avoid fast charging at some stage during my session.

   

  What is the recommendation between these 2 technologies? What is the more reliable of the two for this application? 

   

  Thanks

   

  Peter
