<DIV>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.</DIV>

<DIV>Who is using those batteries? Reports good or bad are welcome. </DIV>

Charlie has been <BR>> running cycle test experiments where he cycles Thunder Power Pro Lite <BR>> batteries with 2C and 3C charge rates, and 4C discharge rates. His <BR>> experiments have convinced him that 3C charging of Thunder Power Pro <BR>> Lite batteries does not harm the batteries. <BR>> <BR>> This is a major step for electric R/C. Consider a situation with one <BR>> charger, two batteries, and 10 minute flights - low cost, typical <BR>> pattern and sport equipment. Charge times
are inside of 30 minutes. <BR>> Allowing 5 minutes for pack cool-down, it is possible to log 5 flights <BR>> in less than 2 hours. In a pattern situation this isn't yet possible, <BR>> because it takes a 16A charger to charge the 5.3Ah pack at 3C and they <BR>> don't exist. Using available chargers, two TP 1010's ($320-$400), two <BR>> TP 210 balancers ($140-$200), and four 5s4p5300 packs ($1100-$1300), the <BR>> <BR>> time for 5 flights would be something like 130minutes. <BR>> <BR>> 3C charging (currently 2C with pattern packs and available chargers) <BR>> allows you to fly just as much with fewer batteries. That saves outlay <BR>> costs, if not cost per flight, and certainly reduces the length of time <BR>> you are stuck with current technology. <BR>> <BR>> More good news from the electric world. <BR>> <BR>> Those of you planning on charging at >1C, make sure you read Charlie's <BR>> post. He gives specific guidelines and practices. <BR>> <BR>> -Adam <BR>> _______________________________________________ <BR>> NSRCA-discussion mailing list <BR>> NSRCA-discussion@lists.nsrca.org <BR>> http://lists.nsrca.org/mailman/listinfo/nsrca-discussion <BR>> <BR>> _______________________________________________ <BR>> NSRCA-discussion mailing list <BR>> NSRCA-discussion@lists.nsrca.org <BR>> http://lists.nsrca.org/mailman/listinfo/nsrca-discussion </BLOCKQUOTE></body></html>
