Renogy LiFePO4 battery is your best choice for RVs, Marine and Off-Grid Applications when towing or mobility is in consideration. Self-Heating Function Meet our revolutionary self-heating function. This technology allows you to charge your batteries in cold environments effortlessly. When connected to an input, the self-heating function will start operating automatically once the battery temperature drops below 41F (5C). Real-time Monitoring With the improved RS485 UP Communication Port, your batteries will be able to communicate and transfer data in real time. Using a Renogy Bluetooth Module BT2 export the data into comprehensible information streamed straight to your cell phone, or watch it live with a Renogy monitoring screen. NOTE 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.

What are Renogy battery 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 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. Moreover, Renogy batteries have passed the free drop test Electro Magnetic Compatibility testing, forced overcharge/discharge test And crash test. 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 recommend a maximum of 4 batteries in parallel, and our automatic battery balancing system allows you to achieve parallel safely.
