Invicta SNLH31H P31H Hybrid LiFePO4 12V 100Ah 1200CCA Starter Battery

Invicta SNLH31H P31H Hybrid LiFePO4 12V 100Ah 1200CCA Starter Battery

The SNLH31H is a 12V 100Ah hybrid Lithium Iron Phosphate starter battery rated at 1200CCA, built on A123 pouch cells with an engineered BMS, integrated jump start function, and Bluetooth monitoring. Built to P31H case dimensions, it is IP56 rated and IEC certified, supports direct alternator charging, and is backed by a 3-year full replacement warranty.

Product overview

The Invicta SNLH31H is part of the Hybrid Starter range, designed for dual-purpose use across starting and deep cycle applications. Combining 1200CCA engine starting performance with 100Ah of auxiliary capacity, it provides a reliable power source for running 12V accessories including fridges and marine equipment without affecting starting capability. Built around A123 pouch cells, the same cell technology used by Mercedes and BMW, the SNLH31H delivers high-rate discharge and charge performance within a standard P31H case at 330 x 168 x 220/222mm.

The engineered BMS handles continuous high-rate charge and discharge cycles, accepting charge directly from a standard vehicle alternator without requiring an additional DC-DC charger in most installations. A thermal protection layer reduces the impact of engine bay heat on the battery internals, keeping internal temperatures low for reliable performance in high-heat under-bonnet environments. At 10.2kg, the SNLH31H offers a significant weight reduction over equivalent lead-acid alternatives.

Bluetooth connectivity links to the free Invicta app for real-time monitoring of key battery performance metrics and remote activation of the jump start function. The jump start feature automatically reserves a portion of capacity, which can be released when the main capacity has been depleted, ensuring the vehicle can always be started without sacrificing accessory runtime.

Features and benefits

1200CCA output with 100Ah auxiliary capacity: Delivers 1200CCA for reliable engine starting while providing 100Ah of deep cycle capacity for running 12V accessories, combining starter and auxiliary battery functions in a single standard P31H-sized unit.

A123 LiFePO4 pouch cells: Built using A123 pouch cells, the same cell technology used by Mercedes and BMW, providing high-rate discharge capability and charging flexibility across both starting and deep cycle applications.

Engineered BMS for high continuous charge and discharge: The integrated BMS handles continuous high-rate charge and discharge cycles, protecting the battery against overcharge, over-discharge, short circuit, and temperature extremes across all supported applications.

Jump start function: A portion of battery capacity is automatically reserved for jump starting. When the main capacity is depleted, the jump start function can be activated via the Invicta app or directly on the battery, allowing the vehicle to be started without an external jump starter.

Bluetooth monitoring via Invicta app: Integrated Bluetooth connects to the free Invicta app for real-time monitoring of key battery performance metrics and remote activation of the jump start function.

Direct alternator charging: The pouch cell design and engineered BMS accept the varying charge profiles delivered by standard vehicle alternators, removing the need for an additional DC-DC charger in most standard vehicle installations.

Heat resistant technology: A thermal protection layer keeps internal temperatures low in high-heat under-bonnet environments, allowing the SNLH31H to perform reliably in extreme temperature conditions.

IP56 rated enclosure: The battery housing carries an IP56 ingress protection rating, providing resistance to dust and water spray in exposed under-bonnet and outdoor installation environments.

Lightweight LiFePO4 construction: At 10.2kg, the SNLH31H is significantly lighter than an equivalent lead-acid battery, reducing total vehicle weight in weight-sensitive applications.

Standard P31H case dimensions: Built to standard P31H case dimensions of 330 x 168 x 220/222mm with M8 terminals for direct drop-in replacement of existing P31H starter batteries without modification.

3-year full replacement warranty: Backed by a 3-year full replacement warranty, providing long-term confidence in the product's reliability and performance across its rated service life.

Frequently asked questions

Can the SNLH31H be charged directly from a vehicle alternator?
Yes. The engineered BMS and A123 pouch cell design accept the varying charge profiles delivered by standard vehicle alternators. No additional DC-DC charger is required in most standard vehicle installations. Contact us if you have a specific alternator setup that requires clarification.

How does the jump start function work on the SNLH31H?
The engineered BMS automatically reserves a portion of capacity for jump starting. When the main capacity is depleted, the jump start function can be activated via the Invicta app or directly on the battery, allowing the vehicle to be started without an external jump starter.

Is the SNLH31H suitable for under-bonnet installation?
Yes. The thermal protection layer, IP56 rated enclosure, and standard P31H case dimensions of 330 x 168 x 220/222mm make the SNLH31H well suited to under-bonnet installations. Contact us to confirm fitment for your specific vehicle application.

What is the difference between the SNLH31H and other Invicta Hybrid Starter models?
The SNLH31H is built to a standard P31H case size with 100Ah capacity and 1200CCA, making it one of the higher-capacity models in the Hybrid Starter range. Contact us for a full comparison of available Invicta Hybrid Starter models to find the right fit for your application.

What app is used to monitor the SNLH31H via Bluetooth?
The SNLH31H connects to the free Invicta app for real-time monitoring of key battery performance metrics and remote activation of the jump start function. Contact us for information on downloading and setting up the Invicta app for your device.
