The Invicta Lithium SNL12V40S is a premium, compact 12V 40Ah Lithium Iron Phosphate (LiFePO4) deep-cycle battery custom-built to offer elite energy density and flexible configuration options. Perfectly optimised to act as a direct replacement for equivalent standard sealed lead-acid (SLA) batteries, this high-calibre unit can be safely wired in series or parallel configurations up to 4S or 4P. Featuring an ultra-safe chemistry and a built-in Battery Monitoring System (BMS), it successfully minimises the risk of fire or cellular damage under punishing Australian deep-cycle, mobility, and backup operating conditions.

Perfect for drivers who demand:

  • ✓ Up to 8 times the total cycle life of traditional SLA blocks to radically lower long-term replacement overheads
  • ✓ A lightweight power source at close to half the weight of old lead-acid variants with 60% more usable runtime
  • ✓ Clean, non-hazardous phosphate chemistry that safeguards personal health and the local environment

Key Features & Benefits

Inherent LiFePO4 Safety

  • • Premium cell composition provides maximum tolerance against high temperatures and abuse
  • • Extends deep security with superior protection against short circuits, penetration, and overcharging
  • • Low-risk thermal layout makes it highly reliable across demanding Australian conditions

Integrated Internal BMS

  • • Built-in Battery Monitoring System actively keeps individual internal cell blocks balanced
  • • Automatic cut-offs defend cell health against over-discharge and excessive temperatures
  • • Restricts premature voltage decay for a safer, more stable overall auxiliary output

IEC Certified Calibre

  • • Thorough testing on cell and BMS configurations guarantees strict compliance with safety norms
  • • Direct factory-audited construction ensures high structural quality for your complete peace of mind
  • • Elite build standards suit specialised critical power and medical field deployments smoothly

Optimised Deep Cycle Curve

  • • Ultra-flat discharge line maintains consistent, efficient energy delivery throughout the capacity window
  • • Safely achieves over 2000 full cycles at a demanding 100% Depth of Discharge (DOD) routine
  • • Fast recharging traits ensure your portable or emergency gear is ready to go much sooner

Advantages & Considerations

Advantages

  • ✓ Versatile configuration supports up to 4S (series) or 4P (parallel) scaling linking options
  • ✓ Delivers up to 8 times the cyclic longevity of an old lead-acid or standard SLA block
  • ✓ Exceptionally low self-discharge rate is perfect for extended standby storage layovers
  • ✓ High energy density profile cuts regular lead-acid application weight down by half

Considerations

  • • Note: This specific pure "S" variant layout does not feature integrated wireless Bluetooth monitoring
  • • Maximum continuous discharge current is strictly regulated and specified up to 50A
  • • Must be charged via a specific, lithium-compatible (LiFePO4) smart charger to avoid BMS trips

Frequently Asked Questions

Is this battery maintenance-free?

Yes, this battery features a completely maintenance-free layout utilising advanced LiFePO4 cells. The integrated Battery Monitoring System (BMS) automatically manages internal cell balances, so you never have to perform physical checks or fluid top-ups.

What vehicles/applications is this battery compatible with?

This compact 12.8V lithium battery is ideally suited for lightweight deep-cycle setups, including mobility devices, caravan or camping companion setups, minor solar energy storage networks, UPS critical backup lines, personal power packs, and medical equipment.

How should I store this battery during the off-season?

Store the unit in a cool, dry place away from extreme temperatures and humidity. Because of its extremely low self-discharge rate, it can sit unused for long periods; however, it is highly recommended to isolate the terminals and top up the charge periodically with a compatible smart lithium charger to preserve voltage health.

What is covered under the warranty?

The local warranty provides comprehensive protection against operational failures and internal component degradation caused directly by manufacturing material defects or factory assembly faults, subject to standard operating conditions and Invicta terms.
