WHat kind of run time could I expect with a Tekin 1700 in an 8ight e? Does the huge 150c discharge rate shorten the run time?

I got 28 mins yesterday with a tekin 1900kv and same battery...really depends on track and driver too. I would expect a 1700kv to get the same or a little longer. Gearing of couse is important as well.

If anything, the large C rating would give you longer runtimes. 1700kv sounds a little low for 4s. I would guess 25 min runtime.

search for the URC review of the maxamps 6500 pack on youtube. Might be a bit enlightening on what kind of run time you can expect from the 6500 pack.

Coming from an electronics background, I believe that maxamps is saying their packs can release up to 150 amps if necessary. It all depends on what the esc needs at that moment in time. Full throttle going up a hill will require more juice than letting off and going around a corner at 1/4 throttle. If the battery will not discharge enough to "feed the esc" then it will feel less punchy, etc....

C is not amps. Amp discharge capability based on the c rating=the amp hour capacity x the C rating. So what they are claiming on the 6500 pack is it will release up to 6.5x150=975amps. Which is completely ridiculous.

This ridiculous claim has been scoffed at and questioned by anyone that knows anything about batteries since they were released and maxamps has yet to show a single shred of proof that they can actually discharge at that insane rate even for a millisecond.

150 amps is probably realistic discharge capability but again... not what they are claiming.

I own one of the 150C 6500mah packs in 2s for a 4x4 short course truck and it is no better than a 40c pack I have from thunder power. Actually, the thunder power pack seems to keep its punch longer into the run than the 150c maxamps pack.
