SLA batteries are expensive compared to the much lighter and smaller RC lithium ion batteries. that is if you are buying online. Many of those li-ion/lipo batteries will have high capacities and can really deliver a lot of current (some over 100A!). Just make sure to treat them carefully, and use a proper charger.

Use a 12V deep cycle SLA. What more do you need?
