on all three of my 4s lipos it comes up connection break
The 3s it charged to storage level on the battery checker it reads 14%  

I would expect that charger to take the cells to 3.85V for a storage charge.
You can alter the charge rate. Once the type of charge is selected by pressing the start button once the charge rate flashes. The middle buttons (+ -) raise or lower the charge from 0.1A to 6A  (the limit of the charger). Once set to the required level press and hold down the Start button until it "warbles" and starts. 

Note on a storage charge it automatically decides if the cells need charging or discharging to reach storage level. The maximum discharge rate is limited by the heat dissipation capacity of the charger. Too high a discharge rate and the thermal cut may operate. If it does it is pot luck whether it resets itself! 
To avoid this issue I have set both the Discharge and Storage options to 0.5A.

ps
I wouldn't worry too much about "clone" chargers. I am sure both mine are yet they work perfectly. However I don't have any 6s or big capacity LiPo. The highest charge amps I use 3.5A and that is on a 2s.
My chargers thus don't have to work too hard.
