(4) Hyperion 2S 4000 packs for sale

[redshift]

These packs have been perfect, I hate to part with them but my Maxx Mutation is up for retirement. So I have no use for them.
All 4 packs are in excellent condition both physically and performance-wise.

Packs have never:
-been over-discharged (cutoff set at 3.4VPC)
-puffed
-been over 110F
-been out of balance

Packs have always:
-been balance-charged
-been kept at 60-80%

The lock-clips were cut off the balance taps (because they're a pain) but otherwise the plugs and leads have no damage. The main leads had to be extended, and I used gold solder tubes and double shrunk them. They may be cut off if you don't need the extra length.
The packs have been used equally and have around 60 cycles each. They were used about 2 weeks ago and show no signs of slowing down. When I got these packs I absolutely raved about them, and still do. These packs behave like 25C or even 30C packs, and have never broken a sweat even pushing my 15 pound Maxx in 90 degree heat. These are a perfect fit for older Tamiya vehicles which only fit the rounded-side shape. Great for any 2S or 4S application.

I will sell these each, or all 4, would prefer to sell all. Prices will be very reasonable. I do not have Paypal, my first preference would be payment by Postal money order. Also I'd rather avoid international shipping, so US residents only, please. I will ship via UPS.

Please PM for details!
