Overview — Renogy 24V 25Ah Lithium Iron Phosphate Battery (RBT2425LFP-US)
Advanced BMS for Ultra-Safety
The intelligent built-in BMS circuit ensures safe charging and discharging process by protecting the battery from over-charge, over-discharge, over-current, high temperature, and short circuit.
Light and Compact Design
1/3 weight of the lead-acid battery. Replace 12V batteries in series with a one-step 24V solution, save space, and lower wiring costs.
Smart Energy Saving Mode
When the battery is not charging or discharged, it will automatically switch to energy-saving mode after 30s. With only 3% of the self-discharge rate per month, the battery ensures longer shelf life. No need to charge it constantly during storage.
IP65 Waterproof
The seamless ABS housing gives full protection against dust and other particulates. IP65 waterproof performance, suitable for outdoor scenarios.
Wide Working Temperature Range
Back up your power system in extreme climates. Provide stable power supply from hot summer to cold winter. Charge Temperature Range: 32°F~113°F (0°C~55°C) Discharge Temperature Range: -4°F~140°F (-20°C~60°C)
Auto-balancing Function
Up to 8 batteries can be connected in parallel, with expandable capacity. The auto-balancing function ensures optimal charging efficiency and a longer lifespan.

FAQs — Renogy 24V 25Ah Lithium Iron Phosphate Battery (RBT2425LFP-US)
Q: How to activate the battery?
Answer: The battery is shipped in shelf mode. Before using the battery for the first time, please activate the battery with a charge/discharge current greater than 1A and measure the terminal voltage to validate. Prior to long periods of storage, please disconnect the battery from the system. The battery will enter shelf mode automatically after 30s. In shelf mode, the battery has a low self-discharge rate and can hold the charge for a longer period of time.
Q: Can this battery be used in series to build a 48 volt system？
Answer: No, you can't. These Renogy 24V 25Ah lithium batteries do NOT support connecting in series. They are made ONLY for connecting in parallel using identical batteries, same type (lithium), same capacity (Ah), same voltage (V), same brand (Renogy).
Q: How long will the battery last?
Answer: Our battery is capable of 2000 cycles of perfect charge and discharge, after which the efficiency of the battery will drop to 80% of the factory performance, but it is still very good for your use. If you live a completely off-grid life, calculated at the rate of a full charge and discharge per day, you will be able to use it for more than 5 years.
Q: How many batteries can I connect at most?
Answer: We recommand a maximum of 8 batteries in parallel.
Q: How many batteries can I connect to at most?
Answer: Please connect your batteries in parallel, we recommend a maximum of 8 batteries in parallel, and our automatic battery balancing system allows you to achieve parallel safely.
Q: Can I pair a bluetooth Module for this battery to monitor the battery status on phone?
Answer: No. This battery is not compatible with Bluetooth module. You can use 500A Battery Monitor With Shunt to monitor battery status (which is sold separately).
Q: Can you recommend a solar charge controller for this 24V 25Ah battery?
Answer: When purchasing a solar charge controller, ensure that the controller is compatible with the lithium iron phosphate battery. The Renogy Rover and Wanderer Series Charge controllers are fully compatible with our lithium-iron phosphate batteries. You can charge this battery with Rover Elite MPPT charge controller or 10A AC-to-DC LFP Portable Battery Charger.
