Astro Lithium 12V 100Ah Deep Cycle Battery

Our best selling battery, the Astro Lithium 12v 100Ah Lithium Battery is our most versatile option available. Able to run in both series or parallel ensures there is no job this battery cannot handle. This battery is most commonly used for replacing Group 27 or 31 batteries, but with significant weight savings and a huge boost in performance. Depending on the application, the 12v 100Ah will power your needs for twice as long as a traditional Group 27 lead acid battery, all while being about 40 pounds lighter! Our superior cell density means this 100Ah battery is smaller and lighter than other 100Ah lithium batteries. But don't take our word for it, see for yourself. While this battery is equivalent in dimensions to Group 24 battery, most competitors are at a Group 27 sized battery to equal the same capacity as us.  IP65 rating enclosure means high tolerance to harsh environments with exposure to dust and water.  Zero maintenance required. Can be mounted in any orientation. Upside down
