Product Overview
This 24V 300Ah LiFePO4 battery pack is built for deep-cycle energy storage applications where long service life, stable discharge performance and lower maintenance are important. Compared with lead-acid battery banks, LiFePO4 technology offers higher usable capacity, faster charging capability and better long-term lifecycle cost.
The battery uses a metal enclosure for stronger mechanical protection and is suitable for RV compartments, motorhome auxiliary systems, marine cabins, off-grid solar systems and mobile power installations. The BMS can provide protection against over-charge, over-discharge, over-current, short circuit and temperature-related risks.
For B2B buyers, Chalongfly can support customized configuration, including communication protocol, connector type, enclosure design, cable outlet, branding, label, mounting method and project-specific documentation.

Problems This Battery Helps Solve
Heavy Lead-Acid Battery Banks
LiFePO4 battery packs can significantly reduce system weight compared with traditional lead-acid battery banks, helping RV and mobile power systems improve payload and installation flexibility.
Limited Usable Capacity
Lead-acid batteries are usually limited by usable depth of discharge. A LiFePO4 pack can provide higher usable energy and more stable voltage output during discharge.
Slow Charging
With proper lithium-compatible charging equipment, this 24V 300Ah battery can support higher charging current and shorter recharge time than many lead-acid systems.
Short Replacement Cycle
LiFePO4 technology is suitable for users and fleet operators who need longer cycle life, lower maintenance and better lifetime cost across repeated deep-cycle use.
Application Scenarios
- RV and motorhome auxiliary power: For lighting, refrigerator, water pump, fans, electronics and inverter-supported loads.
- RV retrofit and battery replacement projects: For upgrading 24V lead-acid battery banks to LiFePO4 systems.
- Off-grid solar storage: For mobile solar energy storage and independent power systems.
- Marine and cabin power systems: For damp or space-limited environments that require stable deep-cycle battery performance.
- Emergency and mobile backup power: For portable living, campsite power, service vehicles and field operation systems.
- OEM and distributor projects: For RV equipment brands, battery distributors, retrofit companies and system integrators.

Important Compatibility Notes
Before replacing a lead-acid battery bank with a LiFePO4 battery, the complete system should be checked, including charger voltage, charging profile, inverter surge load, cable size, fuse rating, mounting space, ventilation, communication requirement and battery compartment structure.
Series or parallel expansion should not be assumed by default. The correct configuration must be confirmed according to BMS design, system voltage, balancing strategy and actual load profile.

FAQ
Can this battery directly replace a 24V lead-acid RV battery bank?
It is designed for 24V LiFePO4 replacement projects, but the charger, inverter, fuse, cable size, mounting space and protection settings must be checked before installation.
What charger should be used?
A lithium-compatible CC/CV charger with a recommended charge voltage of 29.2V should be used. Existing lead-acid chargers should be reviewed before use.
Can the battery be charged in cold weather?
The listed charge temperature range is 0°C to +45°C. Charging below freezing should be blocked by BMS protection to reduce the risk of cell damage.
Can this battery support communication with the RV system?
RS485, CAN and Bluetooth communication options can be provided depending on the final project configuration and integration requirements.
Can the battery be connected in series or parallel?
Series or parallel expansion must be confirmed according to the BMS design, system voltage, current requirement and installation scenario. Please do not connect multiple packs without technical confirmation.
What documents can be provided for shipping?
UN38.3, MSDS and related transport documents can be prepared depending on the final product configuration and shipment requirement.
Can Chalongfly customize this battery for distributors or OEM customers?
Yes. Chalongfly can support customized battery capacity, BMS settings, communication, connector type, cable outlet, enclosure design, label and packaging for B2B orders.
