Humsienk LiFePO4 batteries offer a significantly longer lifespan (6000+ deep cycles), half the weight, faster charging times, and 100% usable capacity without voltage drop. They also contain zero toxic heavy metals, making them a safer, more eco-friendly power source.

We strongly recommend using a dedicated Lithium (LiFePO4) battery charger with the correct voltage profile. Old lead-acid chargers or chargers with improper voltage settings may not fully charge the battery or could trigger the built-in BMS protection.

If storing the battery for an extended period, charge it to about 50%–60% capacity, disconnect it from all loads, and store it in a dry, well-ventilated area between -10°C and 35°C. Recharge the battery every 3 to 6 months to maintain optimal cell health.

Yes, depending on the specific model. Most of our batteries support parallel and/or series connections to increase your system's voltage or capacity. Always ensure all connected units are of the exact same model, batch, and fully charged to the same voltage level before connecting.

Every Humsienk battery is equipped with an advanced Smart Battery Management System (BMS) that protects against over-charge, over-discharge, over-current, short-circuit, and extreme high/low temperatures, ensuring maximum safety and operational stability.

We ship directly from our local European warehouses with standard delivery taking 2–5 business days depending on your location. All Humsienk batteries are backed by our reliable local warranty and professional customer support team to assist you anytime.
