I have four 2s 6000mAh MaxAmps packs, none of which have more than 20 cycles. Since I've had them, they have always been used with an LVC and balance-charged with either a Hyperion 1210i + LBA10 or a Hyperion 0610iDUO w/ built in LBA10 balancers.

I tested them one by one in my Kyosho Kanai III with a MM/9XL/UBEC. I also tested a True R/C 2s 8000mAh pack just to compare it because it's rated roughly the same as the others. I tried to run for the same amount of time on the same terrain.

Keep in mind that the True R/C pack is new and the MA packs are used, but they haven't been abused, never been over 100F, never been run without an LVC, and can't have more than 20 cycles on them.

MaxAmps 2s 6k:
# 20C Constant(120 amps)
# 30C Sustained(180 amps)
# 50C Burst(300 amps)

True R/C 2s 8k:
Up to 120A continuous
160A Max burst

So, what are your thoughts?


PS. I'll be posting this in the Traxxas forum too, so you might see it twice if you frequent that place too.

Very interesting data. Thanks for posting.

So 2 packs aren't even living up to 10C.
1 Pack is barely doing 10C
The best pack out of the 4 is barely doing 15C?

The Best performing pack on the chart is made from 10C cells!

I realize you didn't want to destroy what is left of your packs.

But if you had your LVC set at 3.0 for this test. Then this explains the bottom of the graph.

If testing were done with No LVC, there's no telling where the bottom lines would be.
