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.

So far so very good

Jon Newlyn on Nov 9th 2021

We chose this battery as an alternative to a deep cycle lead-acid battery, that needed to be 220aH as we had calculated a 1000 wH usage. The size of the deep-cycle battery was a problem. The Renogy was much smaller and lighter (weight is a factor in a van conversion). Plus I could use ALL of the 100 aH, whereas I could only use 50% of the 220aH without damage. The shelf mode is brilliant as I can connect everything up without fear of shorting anything and it's pretty good looking as well. I haven't used it in anger yet, but so far very impressed.

100ah Lithium iron phosphate Battery

Martin on Aug 16th 2021

Cannot fault this battery, i purchased x2 of these and are not disappointed, they hold at 13.25v all day long unless i have the inverter on powering something and then they only go down to about 12.9v ish but for just small bursts and then straight back up to 13.25v again... my only regret is not buying these sooner.
