I have a couple of Venom 5400 3s 20c packs. I got these for a Traxxas Bandit VXL I had and since sold the buggy. These both run/charge/balance fine. I charged these on my Cellpro 4s only a handfull of times before I sold the buggy. Packs were bought used so unknown amount of cycles on them but still seem really strong.
These new go for $149 each. I'd take $100 shipped a piece for these. Take the pair for $175 shipped!
Paypal is preferred for payment and shipping is CONUS/Canad only please.
