Invicta SNL12V20S 12V 20Ah LiFePO4 Deep Cycle Battery M6

The SNL12V20S is a 12V 20Ah Lithium Iron Phosphate battery with aluminium-encased prismatic cells, solid busbar connectors, and an integrated BMS. Weighing 3.0kg at 180 x 76 x 166mm with M6 terminals, it is IEC certified, rated for over 2,000 cycles at 100% depth of discharge, supports 4S/4P configurations, and is backed by a 7-year full replacement warranty. No Bluetooth monitoring is included on this model.

Product overview

The Invicta SNL12V20S is part of the Invicta Lithium range, built on high-grade aluminium-encased LiFePO4 prismatic cells with solid busbar connectors and an integrated BMS developed in the same factory as the cells. At 3.0kg and 180 x 76 x 166mm, it is one of the more compact and lightweight options in the Invicta range, suited to applications where space and weight are key considerations.

The integrated BMS is engineered for Australian conditions and provides automatic protection against overcharge, over-discharge, temperature extremes, and short circuit. IEC certification has been achieved at two levels: IEC62619 on selected models covering the entire battery including cells and BMS, and IEC62133/UL1642 across the entire range at the cell level. Independent testing in Australia confirmed over 2,000 genuine cycles at 98% depth of discharge over more than 1,000 days of operation.

Series and parallel configurations up to 4S and 4P are supported, allowing higher voltage or higher capacity systems to be built from multiple units. No built-in monitoring is included on this S model. A 7-year full replacement warranty is available in approved applications, backed by SPB. This battery is not suitable for under-bonnet or starting applications.

Features and benefits

12V 20Ah LiFePO4 with aluminium-encased prismatic cells: High-grade aluminium-encased LiFePO4 prismatic cells deliver stable, safe energy output in a compact 180 x 76 x 166mm form factor, suited to deep cycle applications where space and weight are critical.

2,000+ genuine cycles at 100% DOD: Independently tested in Australia to over 2,000 genuine cycles at 98% depth of discharge over more than 1,000 days, providing up to 8 times the cycle life of an equivalent SLA battery and a lower total cost of ownership.

30A continuous discharge, 55A pulse: Supports a maximum continuous discharge current of 30A and a 55A pulse discharge for up to 3 seconds, handling high-draw loads across a range of deep cycle applications.

Integrated BMS engineered for Australian conditions: The integrated BMS, developed in the same factory as the cells, provides automatic protection against overcharge, over-discharge, temperature extremes, and short circuit.

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.

Dual IEC certification: Carries IEC62133/UL1642 certification at the cell level across the entire range, with IEC62619 certification available on selected models covering the complete battery including cells and BMS.

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.

60% greater capacity utilisation than SLA: Provides 60% more usable capacity than an equivalent SLA battery and up to 2 times the runtime, translating directly to longer effective run time per charge.

Lightweight at 3.0kg: At 3.0kg, the SNL12V20S weighs less than half of an equivalent SLA battery, significantly reducing total system weight in portable and weight-sensitive applications.

Fast recharge capability: Accepts a maximum charge current of 20A with a recommended charge current of under 10A, returning the battery to full charge sooner than equivalent SLA alternatives.

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 SNL12V20S have built-in monitoring?
No. The SNL12V20S 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.

Can the SNL12V20S be used in an under-bonnet or starting application?
No. The source data confirms this battery is not suitable for under-bonnet or starting applications unless specifically approved by Invicta. It is designed for deep cycle applications. Contact us if you have a specific application that requires clarification.

Can the SNL12V20S be wired in series to create a higher voltage system?
Yes. The SNL12V20S supports series configurations up to 4 units, producing a maximum of 51.2V nominal when 4 units are wired in series. Always confirm that your charger and connected equipment are rated for the resulting voltage before configuring in series.

What type of charger is required for the SNL12V20S?
The SNL12V20S requires a LiFePO4-compatible 12V charger with a maximum charge current not exceeding 20A and a recommended charge current of under 10A. 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 SNL12V20S and a Bluetooth model?
The SNL12V20S 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.
