The Renogy Smart Lithium Deep Cycle Battery enables auto-balance among parallel connections and provides more flexibility for battery connection. The integrated smart battery management system (BMS) not only protects this 12V 100Ah LiFePO4 battery from various abnormal conditions, but monitors and manages the charging/discharging process. The state-of-the-art battery cells ensure a long cycle life and exceptional discharge performance. Suppose you’re searching for a deep cycle battery for caravan, cabin, or marine use. In that case, this lightweight, auto-balanced, ultra-safe, long-cycle-life lithium-ion battery is the perfect plug-and-play solution for you!

Now you can unlock monitoring features exclusively using the Monitoring Screen for smart lithium batteries or the BT-2 Bluetooth Module and Renogy DC Home App!


● Please secure all cable connections to the proper specification in order to ensure good contact between the cable lugs and the terminals. Over-tightening cable connections can cause terminal breakage, and loose cable connections can cause terminal meltdown or fire.
● DO NOT string the battery in series. ONLY connect batteries of the same manufacturer and model in parallel.
● Please avoid too high a voltage difference between paralleled batteries, despite the auto-balancing function, to avoid triggering the over-current protection.

Key Features

  • State-of-the-art battery cells ensure a lifespan of more than 4000 cycles, 100A continuous discharge current, and a wide range of operation temperature.
Reliable BMS System
  • The state-of-the-art battery management system (BMS) with high-performance dual-processors provides short circuit, over charging and over-temperature protection while maintaining a balanced voltage across all cells.
Activation switch
  • The battery with an activation switch will allow you manually get into the shelf mode, the battery will have a very low self-discharge rate in the mode and can hold the charge for a longer period. To better protect your battery when not in use.
Auto-balancing Function
  • Easily connect multiple batteries in parallel with the auto-balancing function to improve the average charging efficiency for your batteries in the long term.
Real-time monitor
  • The battery features RS485 communication ports—enabling communication between batteries, external devices (BT-2 Bluetooth Module or Monitoring Screen) and host computers for you to monitor the charging status in real-time in Renogy DC Home APP.

Warranty Information

Warranty 5-year prorated warranty
1. What are Renogy battery’s greatest advantages?
Firstly, our batteries use the most up to date pouch cell technology. Currently, there are a few battery brands on the market using pre-used battery cores, these have a negative impact on the battery’s life span and present safety risks. In addition, Renogy batteries feature, self-heating functions, an auto-balancing system and an advanced and efficient BMS system. Finally, we provide a 5 year industry leading warranty on all Renogy batteries.
2. What is the specific soft package cell mentioned just now?
Soft package cell refers to the use of aluminum-plastic film as the packaging material of the cell. At present, the vast majority of lithium-ion batteries on the market still use metal shell cells. Compared with the metal shell of the same capacity, the soft pack battery is light in weight and has good cycling performance. When safety problems occur, gas and heat can be released through the sealing mouth to avoid the further triggering reaction. Steel and aluminum cells have the possibility of explosion.
3. What does the external battery switch do?
Our battery is connected with a battery switch, which can turn off the battery and the BMS system with one key when the battery is not needed to work, reducing the self-consumption of the battery, making it safer to store, and protecting the battery life.
4. How long will your battery last?
Our battery is capable of 4000 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.
5. How many batteries can I connect to at most?
Please connect your batteries in parallel, we recommand a maximum of 4 batteries in parallel, and our automatic battery balancing system allows you to achieve parallel safely.

Ok so far

Daniel on Feb 18th 2023

The renogy software predicting battery life is not accurate. I find the battery output voltage can vary in a non-uniform way from full charge to empty. And so at times I have difficulty predicting how much charge is in the battery - both when charging and discharging.

100ah Lithium Battery

Seems like a great battery so far. Lasts well and great price.

Very happy

Geoff on Apr 20th 2022

I have purchased 2 of these batteries which i am running in parallel, put the system to the test over the Easter weekend and I am very happy with the performance.

100 watt smart Lithium battery

Gilbert Pfitzner on Mar 9th 2022

Bought a renogy 100 watt Lithium battery sometime back and so impressed have bought a second one. Impressed by how quickly they recharge and how much better they are than AGM batteries being able to use more amps out of the battery. Can monitor both batteries from my smartphone. Set up in off road camper and while one battery runs everything the other is always available to swap in when needed.

very good quality, I love the idea that you can parallel more than 2 batteries

good batteries

Ethan Eu on Nov 19th 2021

I bought 3 of these. I love the safety feature of being able to put the batteries in shelf mode while connecting accessories, as well as being able to monitor the batteries connected in parallel. The first time setting up the app I could only see 2 batteries, but after a while of troubleshooting I just tried scanning through the app again and all 3 showed up. The batteries didn't come with any cables, so I used the cables that came with the inverter to join the 3 together in parallel. Renogy sells battery interconnect cables but they're all black, whereas the ones that came with the Renogy 3000w inverter are red and black, which I prefer. When connecting the inverter to this battery bank I had trouble trying to find suitable cables and fuses capable of carrying 350 service amps or 400 amps in a fault condition. When using an ANL fuse holder with a 300A fuse, the fuse holder became incredibly hot, even to hold, and probably would have melted if I had continued to boil water (only 170 amps). After some research I finally bought a class T 400a fuse /w holder and 4/0 awg cables from Amazon US, and they work perfectly with this battery bank. I wish Renogy would sell 4/0 awg cables and fuses that match what their products are capable of producing/consuming, e.g. 4 batteries in parallel each capable of 100a discharge will give 400 amps continuous discharge capability, which needs a correct sized fuse to protect the wiring.
