Limitless Lithium LL3.5A-MTN-SV 3.5A 12V Stock Voltage Battery Maintainer
Keep your 12V lithium battery system charged, maintained, and ready with the Limitless Lithium LL3.5A-MTN-SV 3.5A Stock Voltage Battery Maintainer. Designed for compatible LiFePO4 and Sodium-Ion (SIB) battery systems, this automatic smart maintainer provides a convenient way to maintain battery voltage during periods of inactivity without continuously applying charging current.
The LL3.5A-MTN-SV is engineered specifically for standard-voltage lithium battery applications and is recommended for compatible Limitless Lithium Nano, Retro Pro, and No-Li batteries. With up to 3.5 amps of automatic charging output, it is an excellent solution for maintaining high-performance battery banks used in car audio, marine, powersports, and other demanding electrical applications.
Smart Automatic Battery Maintenance
This Limitless Lithium battery maintainer features intelligent charging technology designed to make long-term battery maintenance simple. Once the battery reaches a full charge, the maintainer shuts completely off, reducing output to 0.0 amps. If the battery voltage later drops to approximately 13.0 volts due to current draw, the maintainer automatically turns back on to resume charging. This makes it an ideal set-it-and-forget-it battery maintenance solution for vehicles and equipment that may sit unused for extended periods.
The built-in intelligent microprocessor and Smart Off technology help regulate the charging process, while the integrated LED display provides convenient charging information. Multiple protection features—including thermal, reverse-connection, overcurrent, and overcharge protection—help provide dependable operation.
Designed for Lithium Battery Systems
Unlike conventional automotive battery maintainers, the LL3.5A-MTN-SV is designed for compatible lithium battery chemistries. It supports 12V LiFePO4 and Sodium-Ion batteries, making it particularly well suited for modern high-performance electrical systems where maintaining the correct battery voltage is important.
The maintainer also includes a Battery Repair Mode with 2.0A output for compatible deeply discharged batteries, adding versatility to an already capable charging and maintenance system.
