FAQs — Renogy 24V 50Ah Lithium Iron Phosphate Battery (RBT2450LFP-US)
Q: How to activate the battery?
Answer: The 24v batteries are 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 24v lithium battery from the system. The battery will enter shelf mode automatically after 30s. In shelf mode, the 24v lithium 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 lithium batteries do NOT support connecting in series. They are made ONLY for connecting in parallel using identical 24v 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 3500 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 10 years. As a high-end 24v deep cycle battery, the Renogy 24v battery features all-around IP65 Waterproof, making it suitable for most outdoor scenarios, such as a 24v trolling motor battery or a 24v marine battery. The seamless ABS housing protects the battery against dust and other particulates.
Q: Can I pair a bluetooth Module for this battery to monitor the battery status on phone?
Answer: No. This 24v lithium ion battery is not compatible with Bluetooth module. You can use 500A Battery Monitor With Shunt to monitor battery status (which is sold separately).
Q: an you recommend a solar charge controller for this 24V 50Ah battery?
Answer: When purchasing a solar charge controller, ensure that the controller is compatible with the lithium battery 24v. The Renogy Rover and Wanderer Series Charge controllers are fully compatible with our lithium 24v battery. You can charge this 24v LiFePO4 battery with Rover Elite MPPT charge controller or 10A AC-to-DC LFP Portable Battery Charger.
