Hi Kailash, Hope u missed my earlier mail. This mod was done in my previous P150 with 60/55HL bulb & the same set-up has been transferred in my current P180 but the HL is stock 35/35. Now the 9ah battery takes care of it easily but I use the DC input very rare. In my P150 which was a KS version I changed the stock 2.5ah battery with a 5ah used battery sourced from my friend. I wld suggest u in future to install a single battery with higher capacity however the output is going to be the same but maintenance & space problem will be reduced.
