[NSRCA-discussion] Landmark for e-pattern: >1C charging

[vicenterc at comcast.net]

Better news is the battery manufacturer that is giving 6 months of warranty.  See the add in the last k-Factor. I think is called Falcon Batteries.  I never seen the brand but the fact that they are giving 6 months warranty is very important.  I hope that the competition start to see this trend and we see warranty going up to a year.

Who is using those batteries?  Reports good or bad are welcome.  

Regards,

Vicente Bortone
