The Renogy Rego 12V 104Ah Super Slim LiFePO4 Battery with Self-Heating is built for tight RV, van, overlanding, marine, and off-grid power layouts where a standard battery case may be too bulky. Its 2.4" ultra-thin aluminum alloy housing helps it fit behind seats, under cabins, in canopies, and in other compact spaces when properly mounted. The battery provides 104Ah rated capacity, 12.8V rated voltage, 200A maximum continuous discharge current, and 290A peak discharge current for 30 seconds. Built-in self-heating allows supported charging down to -4°F when charger power is available, while Bluetooth and CAN communication support monitoring and compatible system integration. With IP67 protection, 6000 cycles at 80% depth of discharge, and an 8-year warranty, this Rego Series battery is a space-saving lithium option for carefully planned mobile and off-grid power systems.
The Rego Super Slim battery measures only 2.4" thick, giving builders more flexibility in compact electrical layouts. Its slim profile helps support placement behind seats, inside canopies, under cabins, or in cabinet-style battery spaces where standard battery shapes may be harder to fit.
The self-heating version is designed to support charging down to -4°F / -20°C when charger power is available. The heating system turns on at 40°F / 5°C and turns off at 50°F / 10°C, helping protect charging performance in colder conditions.
This Renogy Rego battery supports 200A maximum continuous discharge current and 290A peak discharge current for 30 seconds. Bluetooth and CAN communication give users better access to battery status and compatible system data for modern RV, van, marine, and off-grid setups.
The battery uses an aluminum alloy housing with IP67 protection and flame-retardant construction listed in the product specifications. Its compact size, rugged housing, and lithium iron phosphate chemistry support long-term storage planning when installed and operated within Renogy’s documented limits.
The super-slim 2.4" profile helps this Rego battery fit into tight spaces that may not work well with standard battery cases. It is especially useful for mobile layouts where storage space, mounting flexibility, and clean wiring access all matter.
Renogy lists clearance guidance of 1.97" to 3.94" above the battery and at least 7.87" on the busbar side. Check these spacing requirements during layout planning to support safe access, clean wiring, and proper serviceability.
