1 of my LIPOS failed in a week, my balancer aparantly didn't work according to Traxxas on my 5800. Sent in for warranty , expecting to pay $40 (1/2 of the$70 for it new at my Hobby Shop+shipping) but Traxxas uses their List of $110+$5 shipping. Since I paid $5 to ship it - the total I would have had to pay was $55 +5 +5=$65 for a $70 battery?
Told them to keep it, will buy the $25 batteries off eBay in the future - they last longer and can get 2 for the 1/2 price warranty scam
Have purchased over 15 traxxas trucks over the past 4 years, may need to look elsewhere if the fuzzy math persists.
Their warranty / upgrade thing is uselful, but far from reasonable for the actual cost of their parts.
