Redodo’s “Mini” line takes the standard 12V 100Ah format and shrinks the footprint, which matters a lot if you’re working with a tight battery compartment in a small camper, teardrop trailer, or boat. This mini 12V lithium battery gives you the same 100Ah of capacity in a case that’s noticeably smaller and lighter than a standard group 24 or group 27 battery box.
The tradeoff for the compact size is usually a slightly higher price per amp-hour, but for space-constrained builds it’s often worth it — squeezing a full-size battery into a mini enclosure isn’t always an option. If you’re still deciding between lithium and traditional AGM for your build, our Solar Battery Chemistry: AGM vs Lithium DIY Guide covers the practical differences.
What stands out here is the cycle rating — up to 15,000 cycles is well above the 6,000 you’ll see on most standard LiFePO4 batteries, largely thanks to a more conservative depth of discharge rating from the manufacturer. In practice that means this mini 12V lithium battery is built to handle daily cycling for well over a decade without meaningfully losing capacity.
It’s a good fit for small mobile setups — teardrops, small vans, boats, or backup power stations — where physical space is the limiting factor rather than raw capacity. If you have room for a full-size battery, you likely won’t need to pay the premium for the smaller footprint.
