Thin 12V 100Ah LiFePO4 Battery for Narrow RV Compartments
The LINEX Thin 12.8V 100Ah LiFePO4 battery provides 1.28kWh in a 395 × 285 × 110mm low-profile enclosure for RV, marine, 4WD, solar and off-grid installations. It supports 100A continuous and 200A peak discharge, up to 50A charging, IP67 protection and at least 6,000 cycles. Its approximately 11.5kg case suits space-limited projects where charger settings, current limits, mounting and cable protection have been verified. Final selection should follow the published technical specification.

Product Details
The thin 12V 100Ah LiFePO4 battery measures 395 x 285 x 110mm, weighs 11.5kg and stores 1.28kWh, so it slides into narrow RV compartments where a standard 332 x 172 x 218mm case will not fit. The 100A BMS covers a 1,000W inverter.

The flat case is 110mm tall, which leaves room for a bed frame or a bench seat. Plan for 20mm of clearance around the terminals and strap the case down: at 11.5kg it is light enough to move by hand but heavy enough to shift in a crash.
The Thin 12V 100Ah LiFePO4 battery provides 1.28kWh in a 395 × 285 × 110mm low-profile IP67 enclosure. It supports 50A maximum charging, 100A continuous and 200A peak discharge, at least 6,000 cycles and weighs approximately 11.5kg for space-limited installations. It is designed for projects with restricted installation depth.
Common FAQs
The battery is intended for space-limited RV, marine, 4WD, solar and off-grid systems. It provides 1.28kWh of rated energy and up to 100A continuous discharge. Confirm system voltage, load current, operating time, installation space, charger settings and cable protection before selection.
Start with 1.28kWh of rated energy, then apply usable depth of discharge, conversion losses, temperature, cable losses and reserve capacity. Divide usable watt-hours by the measured load in watts for an initial estimate rather than relying on Ah alone.
Confirm the published 395 × 285 × 110mm enclosure and approximately 11.5kg weight, then allow clearance for terminals, cables, mounting, ventilation and service access. The supporting structure must safely carry the installed battery.
Replacement requires checking nominal voltage, charger profile, alternator or DC-DC charging, inverter settings, low-voltage protection, terminals, dimensions and maximum current. A similar physical shape does not confirm electrical compatibility.
Only when the model specification and BMS support the planned configuration. Use identical batteries with matched age and state of charge, equal cable paths and correctly sized protection. Confirm the maximum supported configuration before installation.
Use the charging, discharge and storage ranges published for the selected model. Charging below the minimum specified temperature is not supported unless the battery provides suitable low-temperature charging protection.
Compare the application load and surge current with the published 100A continuous-discharge limit and any model-specific peak limit. The BMS does not replace correctly sized cables, fuses or breakers and charger settings.
Documentation for UN38.3, CE, RoHS and applicable model certificates is available, with a 5-year warranty. Confirm destination-market requirements and provide the application, quantity and destination with the inquiry.
