2015 Aerolite 288RLSS lighting change

Hello All
I'm thinking of replacing the existing bulb lighting to LED lights. Currently the lights are push-ins type that get HOT (2 bulbs to fixture) how difficult would it be to go LED.
RV Battery: One Interstate deep cycle SRM-24 550CCA 690MCA Is it better to have two batteries and what benefits with two???
Thanks Norm

It is as simple as pulling the old out and plugging in the new one. Be careful not to damage the socket. LED bulbs only use about 10% of the power incandescent bulbs use. I changed mine to LED some time ago.

If you go with 2 12 volt batteries, you will double the amps available. Connect them in parallel.

You have approximately 48 amps with your 1 battery at the 20 amp hour rate. 2 Batts will give you 96 amps. However, remember, you should only draw them down to 50% or less to avoid damage. So 2 batteries will give you 48 amps drawn down to 50%. The reason you don't have many amps in that battery is it's not a true deep cycle battery. Marine and RV "deep cycle" batteries are rarely rated using the industry standard 20 amp hour rate. They are either estimated or not mentioned at all. Go look at a GC 2, 6 volt battery. Most are rated for over 200 amps at the 20 hour rate. 2 6 volts in series gives 200 amps at 12volts. GC stands for golf cart. They are true deep cycle batteries.

What does this mean to you? Well... Each 12 volt light bulb you run uses about 1amp per hour of use. Your fridge electronics, built in C02 detector and the like each draw power all the time. If you add up the power used in your rv, you will find why so many rvrs go with multiple 12 volt battery banks or multiple 6 volt batteries....To give them enough power available without damaging their batteries by drawing then down to far.

Apologies for long post. Search the archives, the internet for further explanation. Short answer? Get 2 batteries. Get the same battery for#2 as you already have. It's even better to buy both batteries at the same time. Same age, same capacity.
