[NSRCA-discussion] Falcon F3A batteries follow up

[Stuart Chale]

I think that their warranty is rather impressive.  Pack degrades after 100
cycles within 6 months of purchase as long as you didn't crash it or they
can somehow prove that you overheated it and they fix or replace the pack.

I don't think you can ask for much better wording of a warranty.

Warranty verbage seems to exclude anything of high amperage outside of
receiver/servo

loads (i.e. typical pattern plane use). Has anyone been successful in
warranty negotiating a new

battery pack that has been used for Hacker, Axi etc. electric motors?

Just a follow up on the Falcon battery discussion.  

George sent me some additional info on the batteries and their warranty.
The warranty is worth looking at.

First his clarification of a statement where he said that their batteries
are heavier and therefore more robust than TP.

As you say, heavier doesnt necessarily mean better.  You are correct, at
least in principle, that newer technology can yield a higher energy/mass
ratio.  As I am fond of telling people, LiPos exist in a give and take
world.  Given the current chemistry remains constant, one can make design
changes which can swing the pendulum in favor of energy or they swing the
pendulum in favor of cycle life.  You have probably noticed 20C batteries
are typically heavier, more expensive, and do not, (in many cases), have a
favorable cycle per dollar ratio.  At another point in the spectrum is the
lighter cell which yields relatively high energy but with less weight and
lower cycle life. The cell design in the F3As is a combination designed to
yield high energy and high cycle life.  So, when I say! , robust, I mean
our cells are a little heavier than some but they should deliver equal or
superior performance and last longer.  Combined with the zero-delta
matching, these packs should far outlast normal or lite packs. 

 

The warranty on these packs is as follows:

 

   Falcon F3A Pro Series Batteries are warranted against failure, under
normal conditions in typical pattern aircraft use, during the first 6
months from date of invoice.  Examples of failures eligible for pack
replacement include, but are not limited to, manufacturing defects, defects
in workmanship, failure to achieve  proper cell balance, cell failure,
inability to maintain proper voltage during discharge, significantly
diminished mAh capacity, cell/pack swelling not due to misuse. There is no
limit on the number of cycles during the warr! anty period. A failed pack
will be replaced or repaired free of charge, provided failure is not the
result of customer abuse. Some examples of abuse include misuse, crash
related damage, improper charging / discharging, shorting, operation outside
of upper temperature limits (150 degree F), and mechanical damage. Warranty
decisions are on a claim-by-claim basis with emphasis on customer
satisfaction.
