Renogy 12V 104Ah Super Slim Solid State Lithium Battery

Short Product Summary

The Renogy 12V 104Ah Super Slim Solid State Lithium Battery packs 1331Wh of usable power into a case just 61 mm thick — up to 72% slimmer than a standard 12V 100Ah battery. Built on next-generation solid-state cells for cooler, safer running and backed by an 8-year warranty, it's made to disappear under a seat, behind a panel or into the tightest camper build while still delivering full power.

Why This Product

Space is the enemy of every camper and off-road build. The Super Slim solves it: the same 104Ah capacity you'd expect from a bulky underseat battery, in a flat, stackable case that fits where nothing else will. The solid-state chemistry uses around 70% less liquid electrolyte than a normal lithium cell, so it heats up roughly 9× slower and shrugs off the vibration and temperature swings of South African trails. Bluetooth and CAN (RV-C) let you watch every amp from the Renogy app or a Renogy ONE display.

Key Features

• Ultra-slim 61 mm profile — up to 72% thinner than a standard 12V 100Ah battery, ideal for underseat and hidden installs
• Solid-state cells — around 70% less liquid electrolyte and about 9× slower temperature rise for safer, cooler operation
• 1331Wh / 104Ah usable at 12.8V for serious off-grid runtime
• Bluetooth + CAN (RV-C) monitoring via the Renogy app and Renogy ONE hubs
• Up to 200A discharge — runs high-draw inverters and appliances
• Vibration-resistant, stackable design with optional mounting and stacking kits
• 8-year warranty

Ideal For

• Off-road caravans, campers and 4x4 builds where space is tight
• Underseat, side-panel or drawer-system battery installations
• Powering inverters, fridges, lighting and 12V systems off-grid
• Anyone upgrading from AGM to a lighter, slimmer lithium bank

FAQ

How is the Super Slim different from a normal 100Ah lithium battery?
It delivers similar capacity (104Ah) in a case up to 72% thinner, using solid-state cells that run cooler and safer — designed to fit underseat and in tight camper builds.

What is a solid-state battery?
It uses a semi-solid electrolyte with around 70% less liquid than a conventional lithium cell, so it heats up far slower and is more resistant to thermal runaway.

Can I monitor it from my phone?
Yes — via Bluetooth in the Renogy app, or over CAN (RV-C) with a Renogy ONE Core or ONE Vision display.

Does it come with mounting brackets?
The battery is supplied on its own; mounting-bracket and stacking accessory kits are available separately — ask us to include them.

Can 4Matt Campers fit it?
Yes — we supply and install Renogy systems in our Bellville workshop and deliver nationwide.
