Performance for Marine and RV Applications

1. Adaptable Power Configuration

The ability to wire the bundle as either 12V 400Ah or 48V 100Ah makes it ideal for a variety of setups — from traditional RV house systems to advanced 48V inverters and boat trolling motors.

2. Long Battery Life

With up to 7,500 charge cycles, this kit can last more than 10 years under normal use. That means less maintenance, fewer replacements, and lower lifetime costs compared to traditional lead-acid batteries.

3. Lightweight and Efficient

Each LiFePO₄ unit weighs about 70% less than a comparable lead-acid battery, making it much easier to install and transport. For RVs and boats, reduced weight translates to better efficiency and improved range or fuel economy.

4. Maintenance-Free Operation

No acid, no corrosion, and no water refills — just reliable energy when you need it. The low self-discharge rate ensures your batteries stay charged even after months of storage.

5. Built-In Protection

The integrated BMS safeguards the system from electrical faults and thermal risks, automatically balancing cells and maintaining peak performance even under demanding conditions.
