KC HiLiTES Flat Lithium Power for Space-Conscious Builds
KC HiLiTES 150Ah Flat LiFePO4 Battery
A low-profile 12.8V lithium iron phosphate battery designed for overland, van, marine, RV, off-grid, and auxiliary power systems where usable space matters.
The KC HiLiTES 150Ah flat LiFePO4 battery delivers 1,920Wh of energy capacity in a wide, shallow steel housing that is easier to package than a conventional tall battery case. Its flat form factor makes it especially useful in drawer systems, cargo shelves, under-platform installs, and other builds where vertical space is tight.
Grade A LiFePO4 cells, IP65 water and dust resistance, and support for up to four batteries in parallel and/or four in series make it a clean foundation for serious 12V auxiliary power builds.
Note: Chargers, wiring, mounting hardware, fuses, switching, and electrical accessories are sold separately unless specifically listed as included in a bundle.
Why This Battery
High-capacity lithium power in a flat, build-friendly package.
Flat Form Factor
The 19.49 x 24.41 x 1.85 in. housing gives builders more placement options than a traditional upright battery, especially in low-clearance cargo and platform systems.
150Ah Capacity
With 12.8V nominal voltage and 1,920Wh of stored energy, this battery is sized for larger auxiliary power builds running fridges, lighting, camp electronics, radios, compressors, and other sustained loads.
LiFePO4 Chemistry
LiFePO4 construction provides long cycle life, superior stability, lower weight than comparable lead acid batteries, and strong discharge performance.
Expandable System
The modular design supports up to four batteries in parallel and/or four batteries in series for builds that need more capacity or different system voltages.
Applications
Built for mobile and remote power systems.
This higher-capacity flat battery is a strong match for overlanding, off-grid power, marine, recreation vehicle, electric vehicle, energy storage, and van life applications. Its flat shape is especially helpful when the battery needs to disappear into a shelf cavity, platform, drawer stack, or other tight packaging area.
For American Adventure Lab PowerPack Rack builds, the KC flat battery format gives you a cleaner way to integrate auxiliary power without handing over your whole cargo floor to a battery box.

Frequently Asked Questions
The main difference is the flat housing. Instead of a tall rectangular case, this KC HiLiTES battery uses a wide, shallow steel enclosure that is easier to package in shelves, platforms, drawers, and other low-clearance areas.
No. This product is the battery only unless a separate bundle specifically lists other components. Chargers, wiring, fuses, switching, and installation accessories are sold separately.
Yes. KC lists the maximum series/parallel configuration as four batteries in parallel and/or four batteries in series.
Yes. The KC flat battery format is the battery family our PowerPack Rack products are designed around. Always confirm the specific vehicle shelf and battery combination before final installation.
