FP Evo 20 4350 packs in razor

[buster1]

Is anyone still using the FP EVO 20 5S 4350 packs in their Razor.

I am but, two out of my four (so far) have failed. These packs are a BIG disappointment to me. For what they cost and, for as easy as I have been on them, they should have lasted more than 35 cycles.

I have not cycled that many times on these packs - but we'll see shortly, I also have the Evo 25 5S3700 packs as well - they seem better,
Thanks,

I've been running those packs in an Ion for a while and then started using them in a Razor. They have been working fine for me for hundreds of flights. I only run about 5 min on mine doing 3D in the Razor. I've gone as high as 6 min, but I don't recommend it. I think the 3700s would be a good choice as well and they would be lighter which would increase performance even more.

Maybe if we had a description of your setup like gearing, headspeed, motor, controller, flying style, etc. there might be some suggestions made that would increase performance. Unfortunately electrics require a lot more info to diagnose why batteries work best for some and not others. I do know that the 4350s (and most of the other batteries) don't like being pushed beyond the 80% usuage number. I know that if I hear the power drop dramatically, then I just toasted a battery by flying too long so I always use a timer.

Hope I can help.
