How to activate the Renogy 12v lithium battery?
Answer: The Renogy 12v 100ah lithium battery is shipped in shelf mode. Before using this 12v lithium battery for the first time, please activate it with a charge/discharge current greater than 1A and measure the terminal voltage to validate. Prior to long periods of storage, please disconnect the 12v lithium batteries from the system. The battery will enter shelf mode automatically after 24 hours. In shelf mode, the battery has a low self-discharge rate and can hold the charge for a longer period of time.
What should I do if the 12v 100ah lithium ion battery shuts off due to the low state of charge(SoC)?
Answer: The battery SOC estimation is an important component of the battery management system. It can be used to describe the energy level available at the battery and is also significant for finding the lifespan of any 12v lithium deep cycle battery. The SOC value ranges from 0% to 100% and represents the battery level.In practice, the best SOC status of a 12v lithium ion battery is 50% of the central SOC level, so the battery should be charged when the SOC reaches 50%, the charging tends will become slower outside the SOC range of 20-80%. Ensure the SOC of the battery at an appropriate level will be able to protect the lithium 100ah battery’s internal ambiance and prolong the battery life. Please disconnect the battery from loads and charge the battery as soon as possible if you found your battery shut off due to the low state of charge. Otherwise, may cause irreversible damage to the battery.
What type of battery cell does this Renogy 100 amp hour lithium battery use?
Answer: Our 12v lithium battery w/bluetooth uses a prismatic cell, which has excellent thermal characteristics. Compared to the 12 volt lithium battery uses the cylindrical lithium cell format on the market, the prismatic cell requires less cooling per energy unit. Additionally, the prismatic cell also offers excellent cycle life expectancies even under high and varied loads,which causes the Renogy battery to be one of the best 12v 100ah lithium battery on the market,ideal to be used for RV battery, trolling motor battery, marine battery, and more.
How long will a Renogy 100 amp hour lithium battery last?
Answer: The Renogy 12v lithium ion battery w/ Bluetooth 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 regular use, such as use as a lithium RV or car battery (with 12v system). 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 this lithium ion 12v battery for more than 5 years.
How many batteries can I connect to at most?
Answer: Please connect your lithium 12v batteries in parallel, we recommend a maximum connection of 8 batteries. The automatic battery balancing system will allow you to achieve parallel safely.
How do I monitor the battery status?
Answer: This lithium 12v battery with a built-in Bluetooth Module, allows you to easily monitor the battery status with your smartphone via Renogy DC Home App. Meanwhile, you can also add Renogy ONE M1 to monitor not only the lithium batteries but also your entire 12v solar system, controlling all your energy with the all-in-one energy control center.
How to keep a Lithium-iron Phosphate battery healthy at low temperatures?
Answer: A Lithium-iron Phosphate battery will not charge and enters a low-temperature protection stage if the charging environment is below 32°F(0°C ). If you buy this Renogy Lithium-iron Phosphate battery without a self-heating function, please pay attention to timely charging it at the appropriate temperature to prevent the battery from overdischarging. Safe charging requires battery temperatures between 32°F and 131°F (0°C and 55°C). By minimizing exposure to conditions that accelerate degradation, Lithium-iron Phosphate batteries can last longer.
What do I need know to connect multiple batteries in parallel？
Answer: When you design to connect multiple batteries in parallel, please keep the length of ALL cables consistent (from the positive end to the negative end). Battery cables (sold separately) should be appropriately sized to handle the expected load. Keep the connection tight by using the appropriate number of washers to allow for as much as possible thread engagement between the terminal, cable lugs, and busbars, without bottoming out the terminal bolt. And it is best to use flexible busbars or dedicated cables to connect batteries together.
Note: DO NOT connect batteries in series. DO NOT connect batteries with different chemistries.
Please use batteries of the same voltage and capacity for parallel expansion. For example, this lithium ion battery is a 12V 100ah battery, please also use the lithium battery with specifications are 12V 100ah for parallel expansion.
