Bought this for a modified traxxas stampede 4x4 running a hobbywing Max10 4000kV combo. Battery arrived well balanced at 4.85v per cell. Managed to run my truck for a full hour regular driving in the backyard and ran out of time before I ran out of battery. Punch is unreal and is well up to par with my high end more expensive Overlander batteries. No issues charging and balancing so far. Very happy with this purchase. Great value for money.
