Invicta SNL12V40S 12V 40Ah LiFePO4 Deep Cycle Battery

Invicta SNL12V40S 12V 40Ah LiFePO4 Deep Cycle Battery

The SNL12V40S is a 12V 40Ah Lithium Iron Phosphate battery with aluminium-encased prismatic cells, solid busbar connectors, an integrated BMS, and a strengthening frame. Measuring 194 x 132 x 170mm, it is IEC certified, independently tested in Australia, and backed by a 7-year full replacement warranty. No monitoring is built into this model.

Product overview

The Invicta SNL12V40S is part of the Invicta Lithium range, developed by SPB with over 25 years of experience in energy storage. Built on high-quality aluminium-encased LiFePO4 prismatic cells with solid busbar connectors and an integrated BMS, it is designed as a direct replacement for equivalent 12V SLA batteries in standard AGM case sizes. The strengthening frame provides resistance to vibration in mobile and vehicle-based installations.

The integrated BMS provides automatic protection against overcharge, over-discharge, over-temperature, over-current, and short circuit. The battery can be installed on either of its sides, though not upside down, providing additional flexibility in tight or unconventional installation spaces. At 194 x 132 x 170mm, it fits standard AGM case positions without modification.

No built-in monitoring is included on the SNL12V40S. External battery monitoring devices are required for state of charge visibility. Contact us for guidance on compatible monitoring solutions for this battery. A 7-year full replacement warranty is available in approved applications, backed by SPB.

Features and benefits

12V 40Ah LiFePO4 with aluminium-encased prismatic cells: High-quality aluminium-encased LiFePO4 prismatic cells deliver stable, safe energy output in a standard AGM case size, designed as a direct replacement for equivalent 12V SLA batteries.

2,000+ genuine cycles at 100% DOD: Independently tested in Australia to over 2,000 genuine cycles at 100% depth of discharge, providing up to 8 times the cycle life of an equivalent SLA battery and a lower total cost of ownership over the battery's service life.

Integrated BMS with automatic protections: The on-board BMS provides automatic protection against overcharge, over-discharge, over-temperature, over-current, and short circuit, ensuring safe operation across all supported applications.

Solid busbar connectors: Bolted busbar intercell connectors reduce resistance at cell interconnects, contributing to consistent performance and long-term reliability across the battery's service life.

Strengthening frame: An internal strengthening frame provides resistance to vibration damage in mobile and vehicle-based installations, supporting reliable long-term performance in demanding environments.

Flexible installation orientation: The SNL12V40S can be installed on either of its sides, though not upside down, providing additional flexibility in tight or unconventional installation spaces.

IEC certified and independently tested in Australia: Carries IEC certification and has been independently tested in Australia, confirming compliance with international safety standards and performance under Australian operating conditions.

Standard AGM case size: Built to standard AGM case dimensions of 194 x 132 x 170mm for direct drop-in replacement of equivalent SLA batteries without modification to the battery tray or housing.

Less than half the weight of SLA: Significantly lighter than an equivalent SLA battery, reducing total system weight in mobile, vehicle, and portable power applications.

Faster recharge and greater capacity utilisation: Accepts a faster recharge rate and delivers more efficient use of available capacity than equivalent SLA batteries, with up to 2 times the runtime per charge.

7-year full replacement warranty: Backed by a 7-year full replacement warranty in approved applications, supported by SPB with over 25 years in the energy storage industry.

Frequently asked questions

Does the SNL12V40S have built-in monitoring?
No. The SNL12V40S is an S model with no built-in Bluetooth or wired monitoring. An external battery monitoring device is required for state of charge visibility. Contact us for guidance on compatible monitoring solutions for this battery.

Is the SNL12V40S a direct replacement for a 12V 40Ah SLA battery?
Yes. The SNL12V40S is built to standard AGM case dimensions of 194 x 132 x 170mm for direct drop-in replacement of equivalent 12V SLA batteries without modification to the battery tray or housing. Contact us to confirm fitment for your specific application.

Can the SNL12V40S be installed on its side?
Yes. The SNL12V40S can be installed on either of its sides, though not upside down. This provides additional flexibility in tight or unconventional installation spaces where a standard upright orientation is not possible.

What type of charger is required for the SNL12V40S?
The SNL12V40S requires a LiFePO4-compatible 12V charger. Using a charger not rated for LiFePO4 chemistry may damage the battery or void the warranty. Contact us for charger recommendations suited to this battery.

What is the difference between the SNL12V40S and a Bluetooth model?
The SNL12V40S is an S model with no built-in monitoring. Bluetooth models in the Invicta range include the suffix BT and feature integrated Bluetooth for real-time monitoring of charge, discharge, capacity, temperature, voltage, and BMS safety features via a free app. Contact us if you require a model with integrated monitoring.
