01 First distinguish between starting batteries and household batteries

The starting battery mainly serves the vehicle starting and related systems, while the living battery is used for household electricity in RVs. The two have different purposes and configurations, so it is not enough to judge whether they are compatible based solely on the statement that they are both car batteries.


                                                                 Figure 1 | Confirm the configuration of two batteries separately; This diagram is for purpose only and not a wiring diagram.

02 Write the power supply demand into specific scenarios

First, explain under what circumstances power needs to be replenished, and then determine what functions the equipment should have. The model and connection relationship of the existing charging equipment should also be provided together.


                                                           Note:Having multiple DC charging functions does not mean that the device can be directly connected to the mains power.

In addition to the power of 03, it is also necessary to verify the entire system
Charging voltage, allowable current, power supply capacity, line conditions, and installation environment need to be considered together. Just by looking at the nominal power, it is impossible to determine how much continuous charging capacity a certain RV can actually obtain. It is also not advisable to apply a uniform charging current ratio based solely on battery capacity. The requirements of battery manufacturers, vehicle power supply limitations, and charger applicability should be used together to determine the configuration.

04 Confirm daily operations and installation
When submitting selection requirements, specify the installation location of the equipment, whether it is easily accessible, and who will primarily use it. This helps to evaluate device viewing, mobile operation, or vehicle matching needs.

                                                                    
                                                                         Figure 2 | EC-D122 product appearance reference; The specific style and configuration are subject to the actual model.

05 Prepare these materials to make the selection communication more specific

You can organize the information according to the following list. Uncertain projects can be marked as "to be confirmed" without guessing the parameters themselves

ENERCHGWe can communicate product selection based on the configuration you provide. If it involves special interfaces, structural installation, or brand matching, personalized customization evaluation can also be further submitted. Continue to learn about suitable solutions for you
