Invicta SNL12V9S 12V 9Ah LiFePO4 Deep Cycle Battery F2 Terminal

Invicta SNL12V9S 12V 9Ah LiFePO4 Deep Cycle Battery F2 Terminal

The SNL12V9S is a compact 12V 9Ah Lithium Iron Phosphate deep cycle battery with an integrated BMS and F2 Faston terminals. Measuring 151 x 65 x 95mm, it is IEC certified, rated for over 2,000 cycles at 100% depth of discharge, and supports series and parallel configurations up to 4S/4P. No Bluetooth monitoring is included on this model.

Product overview

The Invicta SNL12V9S is a compact LiFePO4 battery designed as a direct replacement for equivalent 12V sealed lead-acid batteries in deep cycle applications. The F2 Faston terminals and 151 x 65 x 95mm dimensions support straightforward fitment in standard SLA battery housings and enclosures across a range of applications including critical power, medical equipment, UPS, and portable power packs.

LiFePO4 chemistry provides greater tolerance to high temperatures and abuse conditions including overcharging, short circuit, and penetration compared to other lithium technologies, with a very low risk of fire or cell damage. The integrated BMS actively balances individual cell blocks, with automatic cut-offs protecting against over-discharge and excessive temperatures. IEC certification covers both the cell and BMS configurations, confirming compliance with international safety standards.

The flat discharge curve maintains consistent voltage output throughout the discharge cycle, supporting over 2,000 full cycles at 100% depth of discharge. The maximum continuous discharge current is 9A. Series and parallel configurations up to 4S and 4P are supported, allowing higher voltage or higher capacity systems to be built from multiple units. A dedicated LiFePO4-profile smart charger is required to avoid BMS trip events.

Features and benefits

Compact 12V 9Ah LiFePO4 chemistry: Lithium Iron Phosphate chemistry delivers stable, safe energy output in a 151 x 65 x 95mm compact form factor, designed as a direct replacement for equivalent 12V SLA batteries across deep cycle and critical power applications.

2,000+ charge cycles at 100% DOD: Rated for over 2,000 full charge and discharge cycles, providing up to 8 times the cycle life of an equivalent SLA battery and significantly reducing total cost of ownership over the battery's service life.

Integrated BMS with cell balancing: The built-in Battery Management System actively balances individual cell blocks and provides automatic cut-offs against over-discharge, over-temperature, and short circuit, maintaining safe and stable operation across the full discharge range.

IEC certified at cell and BMS level: Carries IEC certification across both the cell and BMS configurations, confirming compliance with international safety standards including suitability for critical power and medical field deployments.

Series and parallel configuration support: Supports configurations up to 4 units in series and 4 in parallel, allowing scalable battery systems to be built across a range of voltage and capacity requirements.

Flat discharge curve: Maintains consistent output voltage throughout the usable capacity, delivering longer effective run time and more efficient use of available capacity compared to lead-acid batteries.

Extremely low self-discharge rate: Retains charge effectively during extended storage periods, making the SNL12V9S well suited to standby and emergency power applications where the battery may sit unused for extended periods.

F2 Faston terminals: Standard F2 Faston (6.35mm) terminals provide direct fitment compatibility with SLA battery enclosures and housings across a wide range of standard applications.

Lightweight and compact: At 151 x 65 x 95mm, the SNL12V9S weighs close to half of an equivalent SLA battery, reducing total system weight in portable and weight-sensitive applications.

Non-hazardous phosphate chemistry: Phosphate is a non-hazardous material, making the LiFePO4 chemistry environmentally and health-friendly compared to other battery chemistries.
