12V 100Ah 12V Lithium Ion LiFePO4 Dual Purpose Battery (NLX27)
*Compatible with button head bolts, SAE terminal posts, and threaded rods for secure mounting and with Group 27 BCI Size.
Looking for a high-performance battery that covers both starting power and deep-cycle capacity in one compact Group 27 package? The NOCO NLX27 12V 100Ah Lithium LiFePO4 Dual‑Purpose Battery
Dual-purpose design: delivers full starting amperage and true deep-cycle capability, so you don’t have to compromise between a starter battery and a house/house-bank battery. On the NLX27 you get 1400 amps peak starting power and continuous discharge capability around 175 amps.
High capacity: 100 Ah (1280 Wh) of usable power in a 12 V format.
Lightweight and compact: At just 28 lbs (12.7 kg) compared with typical lead-acid equivalents weighing 60 + lbs, installation and handling are easier.
IP66 rated for water and dust resistance — ideal for marine, RV, off-grid, and harsh-environment installations.
Multiple terminal mounting options included: Compatible with button-head bolts, SAE terminal posts, threaded rods, so you can secure it using your existing hardware or adapt easily.
Group 27 BCI size standard: Fits into many existing battery trays and slots designed for Group 27 lead-acid batteries for a “drop-in” upgrade in many cases.
Built-in advanced Battery Management System (BMS): Auto-enabled, providing over-charge / over-discharge / short-circuit / over-current / temperature protection plus active cell-balancing for optimum performance and lifespan.
Ultra-fast recharge capability: With a compatible lithium-charger (such as NOCO’s Genius series) you can recharge at 1C, meaning full charge in about 1 hour under ideal conditions.
Long lifespan: You’ll get thousands of cycles at high depth of discharge — far more than typical lead-acid batteries. For example, the NLX-series claims up to 2,000 cycles at 100% DOD, up to 4,000 at 80% DOD, and 10,000 at 50% DOD.
Comprehensive installation kit included: Handle, multiple terminal posts and bolts, hex keys, covers and caps, safety & warranty documentation. Everything you need to complete installation is in the box.
5-Year Limited Warranty: Backed by NOCO to ensure reliability and peace-of-mind.
Why this upgrade matters:
Ideal applications:
Replacement for Group 27 batteries in automotive, marine, RV or powersports vehicles
Dual-purpose systems where both engine cranking and house/auxiliary power are required
Off-grid power setups, backup power systems, solar companion battery (where 12 V is used)
Environments that demand durability and weather resistance (boats, marine pours, outdoor gear, mobile installs)
Installation & usage tips:
Make sure your battery tray and hold-down hardware are suitable for Lithium LiFePO4 chemistry: secure mounting, good ventilation, proper terminal connections.
While the NLX27 can technically be charged with many quality chargers, using a lithium-compatible charger (like the NOCO Genius series) ensures optimal performance and fastest charge times.
Because the NLX27 supports up to 4 batteries series or parallel (per NOCO specs) you can expand for higher voltage or capacity applications if needed.
Always register your product with NOCO to activate the full 5-year warranty and keep your documentation.
In marine or harsh environments, periodic inspection of terminal covers and mounting hardware is a good practice to maintain reliability.
With the NOCO NLX27, you’re investing in a high-end lithium LiFePO4 dual-purpose battery that outperforms lead-acid in nearly every metric: starting power, cycle life, install ease, flexibility, and total usable energy. It’s a smart upgrade for anyone looking to future-proof their power system.
