I think you need the 12 Volt Power Supply Separately.
As it can charge Max 4.5A, and Output Max Voltage is 4S = 14.8, you need 5A, 12 Volt Power Supply. Cheapest is a 12V/5A transformer based Power Supply. (>40 watt)

Again, you can use CAR battery (12V) for field charge.

Perhaps a little more expensive but a practical solution is to buy a suitable laptop power supply. This too has been discussed earlier in our forum.

Hi Friends
There is a problem with my charger. I connected the battery for charging but is showing 2S but I connected a 3S. I even checked it with Prateek's battery. It shows 2S on 3S. Please help.

If 4s shows as 4s then surely one of contact of charging pin not connect with Charger circuit (mostly any one side). Just open the charger and check if any dry solder or mis-contact is happening.

You can even check by charging a 3s battery by testing which cell not being charged (low voltage after full charge) from charging pins. Then open and fix that.
Also check the continuity of charging pins of charger (2s/3s/4s). You will solve yourself.

Thanks
