Hello everyone,
Last October I purchased a Kraton and at that time, my local Hobby store recommended (based on ARRMA's recommendation... according to them) 2 x 3S ONYX 5400mah 50C batteries. These worked great for a number of months when the unthinkable happened, my Kraton exploded. There was nothing left of it, 80% melted. ARRMA replaced the car and the batteries a couple of months ago (Thank you ARRMA!). I would run the car periodically, never bashing it or even really stressing it but the other day, I was at the track (Next to my Hobby store) when after my 15-20min run, I noticed my 2 x 3S ONYX 5400mAh 50C batteries were all puffed out. It did not look normal at all... So I took them to the store and they checked them and said 2 of the 3 cells in each pack were dead and both of these pack were on the verge of explosion. The store proceeded to tell me these ONYX brand batteries are no longer the recommended batteries by ARRMA as they believe the car is pulling faster than the 50C (discharge rating) can handle, thus damaging the batteries. The store is thinking I should go to at least a 60C or higher rating. When I looked up the Kraton specs, the minimum required was 35C 5000mAh.
I wanted to run this past the forum and get your thoughts.
Also I would like to to hear your experience with the various batteries and what you recommend. I would like to stay running 6S with a relatively decent capacity, but at the same time I don't want to have some HUGE batteries which are not meant to fit the car and throws off the Center of Gravity.
I am interested in hearing for all of you...
