[NSRCA-discussion] Lithium Battery Packs

[chris moon]

Bill - I have a couple of Fromeco packs that are more than 2 years old 
and still are going fine.  I know that the lithium batteries degrade 
with time but it is a slow loss in capacity and probably a rise in 
internal resistance rather than a catastrophic failure with loss of all 
power.  I am keeping a close eye on mine and will toss them when I 
notice a significant loss in capacity. Mine are in sport planes but to 
be honest, I would probably just replace them if they were in my pattern 
plane if they already gave me 2 years of good service.  Just cheap 
insurance.
