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.

6. How to keep a Lithium-iron Phosphate battery healthy at low temperatures?

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.

7. What do I need know to connect multiple batteries in parallel?


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.

9. What should I do when I receive the battery?


When you receive your battery, please be aware that it may have a low State of Charge (SOC) due to the transportation and storage process. To ensure its optimal performance, we recommend charging the battery right away to avoid over-discharge.

If you plan to store the battery for an extended period without usage, we suggest charging it to a SOC of 30% to 50% and performing maintenance every three months. These steps will help maintain its functionality and performance over time.

    Perfect Replacement

    Posted by Colin McCann on Feb 7th 2024

    After having our previous charger cook our lead acid batteries, we took the opportunity to replace them with Renogy 100ah Lithium batteries. There are multiple reasons to go lithium including the weight saving, the space saving and also the ability to drain the batteries well past the 50% threshold of lead acid. Not that we ever expect that we will need this lower floor but to know that we can run inverters and multiple devices and know that we are not even flexing anywhere near the full potential of the Renogy batteries is a great comfort. An added bonus was the inclusion of the free BT-2 module when we bought two was great. We did look to buy the Renogy One Core as an added feature for our van but it does not seem to be available on the EU site but is available on the UK site which is slightly annoying as we would have to pay import duty from the UK which is just not worth the hassle or cost. Would still love the Core One for battery monitoring so maybe a future purchase

    100ah LiFePo battery

    Posted by douglas geddes on Jul 24th 2023

    great auxiliary battery (up to now anyway), does the job, but beware vw t3 owners: it will NOT fit under the drivers seat (it is NOT a low profile battery, despite the claim).

    Incomplete tech specs, poor monitoring tool

    Posted by j1v on May 12th 2023

    The statement "Maximum Continuous Discharging Current: 100 A" in the technical specifications is, in fact, also the maximum peak current. This is because the Battery Management System (BMS) enforces a current limiter very quickly, which can be either advantageous or disadvantageous, depending on your needs. For me, it completely undermined one of the main reasons I purchased these. The software has only limited monitoring capabilities, displaying only current values with a considerable delay. It doesn't provide history, graphs, or other features that software from other brands offers. Otherwise build quality and capacity are both better than average.

    Lifepo4 smart

    Posted by Paul on May 8th 2023

    Bought as a replacement of a cheap AliExpress battery of which the BMS stopped working within a year. For so far satisfied with the renogy battery. I bought three for a parallel setup. Daisy chained with rs485 and the Bluetooth dongle. Works good but you have to restart the connection every time you check the app.

    Hello, the product is good but I think the DC Home app is bad at maintaining the Bluetooth connection. On android.
