The Renogy Smart Lithium Iron Phosphate 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. If you’re searching for a deep cycle battery for caravan, cabin, or marine use, then this lightweight, auto-balanced, ultra-safe, long-cycle-life lithium-ion battery is the perfect plug-and-play solution for you!

The Renogy Adventurer Li and Rover charge controller are fully compatible with this battery.

Please kindly note that the new Renogy BT-2 bluetooth module with RJ45 port is compatible with this smart Li battery.

If you have any questions regarding this product, please submit a case.

  • When connecting the batteries in parallel, a communication cable is not needed to enable the auto-balancing function.
  • When the battery voltage drops to 0V, please reactivate the battery using an external charging device that has the lithium battery activation function.
  • Make sure to tighten the battery terminals securely and use appropriate size wiring. Failure to make a secure connection could result in overheating and battery damage.
  • DO NOT string the battery in series. It is made ONLY for 12V parallel connections using the batteries of the same manufacturer and model.
  • Please avoid too high a voltage difference between paralleled batteries, despite the auto-balancing function, to avoid triggering the over-current protection.


Key Features

  • Connects multiple batteries in parallel safely without internal state non-uniformity issues.
  • The battery management system (BMS) provides comprehensive protection to the battery and manages the charging/discharging process wisely.
Uncompromised Quality
  • 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.
Communication Port
  • The RJ45 communication ports enable data transmission to meet the needs of different usage scenarios.

100Ah Smart Lithium Battery

Philip Evans on Dec 21st 2022

Delivered within a few days, very well packaged. This is my second 100Ah Smart Renogy battery and I have it wired in parallel. Together with the Renegy 1000W inverter, this has provided an excellent emergency backup solution. I hope to expand into solar next year! So far, very impressed with the quality.

I've had four of these batteries now and I'm impressed with the quality and performance. I would highly recommend this company.

Awesome battery, worth the price

Jesse L on Aug 25th 2022

We bought 5 of these batteries for our 5th wheel that we use off the grid. They last a long time, even when using the inverter at night when there is no solar. By the time we get up in the morning the solar has them back to 100%. The smart battery features have allowed me to make a couple of dumb mistakes with the system and keep from damaging the batteries. A+ product.

Excellent Quality Battery

Munaman on Aug 25th 2022

Excellent, quality made battery. I installed two, as coach batteries to my motorhome. I've also paralleled two, getting ready to add a third to a home solar battery bank. They're ight weight, in comparison to lead acid batteries. Easy to connect to BT2, to determine battery state of charge, total Amp Hours, Input and output of batteries, respectively.

Renogy smart battery

Stuart Beardmore on Aug 7th 2022

Just upgraded from AGM batteries to the Renogy 100ah. Just about to go to France for a few weeks so will give it a workout. But at the moment it’s like moving from analogue to digital… it feels very much a premium product… it almost like a super power knowing exactly how much usable power remains. Only issue at present is size is one thing but when I put in the cable to the monitor ( I think rj45) it more or less adds an inch to the over all height… perhaps a lead with 90 degree would be better… 4 stars as one of the best features is the ability to monitor and as the cable changing the dimensions means it has problem fitting the battery compartment. I also have the Renogy 40amp Dc to Dc charger… this is like extra assurance as it can push in an good amount of power into the battery in no time.
