FAQ
LiFePO4 chemistry is famous for its longevity. This battery is built to last for more than 4,000 deep charge/discharge cycles. Even if you completely drain and recharge it every single day, it will last over 10 years while still retaining about 80% of its original capacity.
Packing an incredible 640Ah of capacity into a single case measuring 635 x 244 x 218 mm, this battery weighs approximately 50.75kg . For safety and ease of handling, we highly recommend having two people lift and install it. It should be securely strapped down in your RV or boat to prevent movement during transit. While LiFePO4 batteries can be mounted in various orientations, keeping the terminals facing upward is the standard and recommended practice.
Featuring a rugged IP65-rated enclosure, this battery is completely dust-tight and highly water-resistant. It is engineered to effortlessly handle rain, boat spray, and harsh outdoor environments. That being said, we highly recommend installing it in a standard battery compartment (such as inside your RV or boat cabin) as the ideal way to ensure peak performance and maximize its 10+ year lifespan.
A 12V 640Ah battery holds a massive amount of energy—roughly 8.19 kWh (kilowatt-hours). To put this in perspective, it can power a standard RV refrigerator for over a week, run a 1000W microwave for about 8 hours, or keep your essential home lights and electronics running for days during an outage. It is the ultimate solution for long-term off-grid living.
The BMS (Battery Management System) is the brain of the battery. A 250A BMS means this battery can safely output a continuous current of 250 Amps. Translated to power, it can continuously handle high-drain appliances up to 3000 Watts (like air conditioners, induction cookers, or water heaters) without tripping or shutting down.
No. This is a "deep cycle" battery designed to provide steady, continuous power over a long period. It is not a starting battery (which delivers a short, massive burst of energy to crank an engine). Using it to start a vehicle will trigger the BMS protection and may damage the battery.
Yes! Our batteries support both series and parallel connections. For example, if you are looking to build a massive home energy storage system, you can easily connect 4 of these batteries in series to create a powerful 48V 640Ah (32kWh) system. Always ensure all batteries are fully charged to the exact same voltage before connecting them.
Simply download our dedicated mobile app (available on iOS and Android) and connect to the battery via Bluetooth. The app allows you to monitor the battery's real-time status from your phone, including the State of Charge (SOC%), current voltage, temperature, and remaining capacity, so you never have to guess how much power is left.

You can connect up to 16 batteries in a flexible 4S4P configuration (4 in series and 4 in parallel). This allows you to scale your system from a single 12V 640Ah battery all the way up to a massive 48V 131.07kWh family-scale storage solution. It provides ample capacity for long-term off-grid living and reliable whole-home backup during power outages.
