The SNL12V20BT is a 12V 20Ah Lithium Iron Phosphate battery with integrated Bluetooth monitoring, aluminium-encased prismatic cells, solid busbar connectors, and a built-in 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 parallel configurations up to 4P, and is backed by a 7-year full replacement warranty.
The Invicta SNL12V20BT 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. Bluetooth connectivity allows real-time monitoring of charge, discharge, capacity, temperature, voltage, and BMS safety features from a compatible Apple or Android device from up to 5 metres away. This battery cannot be wired in series due to the Bluetooth integration.
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. 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.
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.
Bluetooth monitoring up to 5 metres: Built-in Bluetooth connects to a free app on Apple or Android devices for real-time monitoring of charge, discharge, capacity, temperature, voltage, and BMS safety features from up to 5 metres away, including in hard-to-reach installations.
Bolted busbar intercell connectors: Solid bolted busbar connectors reduce resistance at cell interconnects, contributing to consistent performance and long-term reliability across the battery's service life.
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.
Parallel scalability up to 4P: Supports parallel configurations of up to 4 units, allowing larger capacity banks to be built. Series configuration is not supported on Bluetooth models.
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 SNL12V20BT weighs less than half of an equivalent SLA battery, significantly reducing total system weight in portable and weight-sensitive applications.
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.

Can the SNL12V20BT 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 SNL12V20BT be wired in series to create a higher voltage system?
No. Bluetooth models in the Invicta range cannot be wired in series. For higher voltage applications, Invicta offers dedicated 24V and 36V battery options. Contact us for guidance on the right solution for your voltage requirements.
What does the Bluetooth monitoring show on the SNL12V20BT?
The Bluetooth app provides real-time monitoring of charge, discharge, capacity, temperature, voltage, and BMS safety features. It is available free on Apple and Android devices and works from up to 5 metres away, making it particularly useful for batteries installed in hard-to-reach locations.
What is the difference between the SNL12V20BT and the SNL12V20S?
The SNL12V20BT includes integrated Bluetooth monitoring for real-time battery health and state of charge visibility from a compatible mobile device. The SNL12V20S is an S model with no built-in monitoring and supports series configurations up to 4S. Both are 12V 20Ah LiFePO4 batteries with identical dimensions and weight. Contact us if you need help selecting the right model for your application.
What type of charger is required for the SNL12V20BT?
The SNL12V20BT 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.
