If you seriously want to reduce weight then lithium would be the way to go but you will need deep pockets . everything else is going to be similar weight to what you are taking out .

(edit --- deleted opening comments about running lights - I mis-read the question)
As was mentioned the relatively expensive Lithium batteries offer a light weight solution, amongst other advantages but any lead acid battery will be heavy. If going that way then choose an AGM deep cycle of about 100 KWH which should weigh at least 30kg. The heavier the better - more lead! People seem to like Full River. If you choose Lithium then you will need to check that your current 'battery charger' will be suitable.
You may do well by reading thru the hundreds of posts on the Solar power section of the Techies' Corner section of this forum.
You could also pick up a lot of good info from 'Outbackjoe' if you google that name. But the many will quite correctly point out that Collyn Rivers books & articles are the bibles of RV Electrics and many other RV topics.

I think you mean 100 AMP,s, not KWH.

Hi
I know the electricity units are confusing, so let us get it right. 100 ahr(amp hour) is the size intended.
I also agree about Collyn River's books as very useful. I have two of them. But the Solar Power sub forum in the Techies' Corner has plenty of reading for free

Oops ... A seniors moment. Yes you're right.

An easy way to reduce weight if you intent is light usage rather than fit a 100ah battery consider either a 50 or 60ah one.
Consider a dual purpose one deep cycle and cranking, like the EXIDE Orbital ORB34DC-48 Dual Purpose Battery or Optima D35 Yellow Top Deep-cycle/Starting Battery 12V 650CCA 48AH

90Ah $205 (plus freight) www.batteryvalue.com.au/
I use a 125Ah version of this for a crank battery in the OKA.
No connection except as a previous customer.
Cheers,

Unfortunately the difference in quality tween batteries that you speak of is in there manufactured weight. My info is that a light weight AGM Battery is usually understated in its quality.

Anyone fitted the smaller battery from a lawn mower ?? Only issue I can see is lowering its voltage . Can buy them for around $120- $200 . Small, light and keep lights going all night . Could even have them In banks ? Just a thought ?? My DC lawn mower is a few years old still works great !

And also not knowing the voltage of a lithium lawn mowing battery, I would like to point out
When I buy 12 volt led lights, for my motorhome interior lights, they usually say 10 to 30 volts

I have a similar problem. Only a 100amphr battery in the van but dont want to add weight. (Telly use) My thought is have an additional battery in the ute. Keep it charged and if required connect to van battery via anderson plugs and lead.

This is OK as long as both batteries are the same type, amh`s, age and chemistry and at the same rate of charge. I have been told that connecting batteries this way is a no no with lithium batteries.
Prior to connecting lithium batteries in parallel both batteries must be fully charged. [This information is from battery suppliers.]
