+1 on HVR. I don't own the packs your listing but I have had an Enerland 2c and one other that escapes me right now. All good packs but for less $ the HVR had the longevity. I have run 2 Summer seasons running one pack in 2 trucks and one winter season running an SC 4wd. I balance the pack after each race day and the pack's cell balance is never more than .01V off of balance before charging.
