It is highly recommended to use a lithium-compatible charger (with a LiFePO₄ charging profile).AGM chargers may work in some cases, but they are not ideal for charging time or battery safety.Using a dedicated lithium charger ensures optimal performance, faster charging, and longer battery life.

Our LiFePO₄ batteries offer 6,000 cycles at 80% depth of discharge (DOD), translating to a lifespan of 10 years or more under normal usage. This is significantly longer than traditional lead-acid batteries.

Absolutely. Our lithium batteries are ideal for solar energy storage systems thanks to their high charge efficiency, long cycle life, and low self-discharge rate. They’re suitable for off-grid set-ups, caravan solar setups, and home solar installations.

Yes. Every battery is equipped with a built-in Battery Management System (BMS) that provides protection against overcharge, over-discharge, overcurrent, short circuits, and high/low temperatures, ensuring safe and stable operation.

When connecting in parallel, ensure all batteries are of the same model, capacity, and voltage. Fully charge each battery before connecting, and use appropriately rated cables and fuses. If series connection is needed, please confirm the model supports it or contact our technical team for guidance.However, do not mix different BMS types (e.g., heating vs non-heating models) in a bank—use identical models to avoid compatibility issues .

Yes. Lithium batteries can be installed in a variety of orientations – upright, flat or on its side, but not upside down. Avoid high-heat, moisture, and vibration-prone environments. For mobile applications like caravans or boats, use secure mounting to prevent movement.

No. Our deep cycle lithium batteries are not designed for engine cranking.

Yes.All models come with integrated Bluetooth modules, allowing real-time monitoring of voltage, current, temperature, and state of charge (SOC) via a mobile app.

Yes. All our lithium batteries comply with international safety and transport standards, including UN38.3, MSDS,RoHS and CE. They are packaged with fireproof, shock-resistant materials and are safe for land, sea, and air transport.

Our lithium batteries come with a 6-year limited warranty, covering manufacturing defects and performance issues under normal usage. We provide local technical support through our German service centers and offer fast replacements or returns when necessary. For assistance, please contact our customer service team.

Yes. Most of our batteries feature IP67-rated enclosures, meaning they are fully protected against dust ingress and can withstand temporary immersion in water up to 1 meter for 30 minutes. This makes them suitable for marine, off-road, and outdoor applications.

Our LiFePO₄ batteries with built-in heating modules can safely charge down to –20 °C. The integrated heater automatically engages when temperatures drop below approx. 0–5 °C, bringing cells to charging-ready levels,protecting cells and enabling normal charging. Discharges are possible down to –20 °C without damage.

When the battery is connected to a charger with sufficient current (e.g., ≥4–15 A depending on capacity), the BMS triggers internal heating until it reaches ~10 °C, then stops automatically.

With lithium, you get 90–98% round-trip efficiency, while AGM batteries typically achieve only 70–85%. This means less wasted energy and a much more efficient system overall.

Yes—with adjustments. You’ll need a charger or DC–DC converter compatible with a 14.4 V LiFePO₄ charge profile. Many vehicles require a step-up or dedicated DC–DC charger to achieve optimal charging .

Our LiFePO₄ chemistry is among the safest lithium options. Even in extreme abuse tests (puncture, short, freeze), they do not catch fire or explode. Robust internal BMS adds further protection .

No—extreme heat (above 60 °C) can damage cell internals and shorten lifespan. We strongly recommend mounting within controlled ambient temperatures for optimal longevity.

Virtually none. Unlike AGM, there’s no need to check electrolyte levels or perform equalisation charging. Just monitor state of charge occasionally
