4. Better cost and high cost performance
The DIY assembly method greatly reduces the labor and brand premium. With the direct delivery of spot goods from the US warehouse, the price of the same capacity is far lower than that of commercial finished batteries at $1,699.
5. Intelligent monitoring and convenient operation
Equipped with a Bluetooth module, it supports mobile phone APP to view the voltage, total current, temperature, SOC and other information of each string in real time; RS485/CAN communication can be seamlessly connected with mainstream inverters.
3. Sharing of real cases of American customers
Case 1: Solar off-grid backup for California households
Customer background:
David is an environmentally friendly household user living in the suburbs of California. He installed a 6kW solar system at home. The original lead-acid battery pack had a small capacity, was difficult to maintain, and had a short life. In April 2024, David ordered a 51.2V 314Ah LiFePO4 DIY battery pack through the BASENGREEN official website.
Installation experience:
“I received the goods on the fourth day after placing the order. All parts were tightly packed and the accessories were complete. It took about 3 hours to assemble step by step according to the instructions. The BMS Bluetooth function is very easy to use, and the battery status can be checked on the mobile phone at any time. Now even if there is a power outage, the family can maintain basic electricity consumption for a whole day, and completely bid farewell to the troubles of lead-acid batteries.”
User feedback:
Daily solar power is directly supplied during the day, and batteries are used for backup at night
The battery cycle depth is generally 20~80%, and the expected life span can reach more than 10 years
Through BMS active balancing, the voltage of 16 strings of batteries is always consistent, safe and worry-free
Case 2: Florida RV upgrade and transformation
Customer background:
Mike is an RV enthusiast who drives across the United States all year round. The original RV battery pack has limited capacity and cannot support long-term operation of high-power appliances such as air conditioners and refrigerators. In May 2024, he chose BASENGREEN’s DIY battery pack for upgrade.
Installation and application:
“The whole installation process is simpler than I thought. All cables, screws and insulation boards are complete. What satisfies me most is the active balancing BMS and Bluetooth monitoring, which allows you to see the power consumption of the RV at a glance. Now you don’t have to worry about running out of power even if you camp in the wild for three days. The solar panel + large-capacity battery is a perfect combination.”
Usage scenarios:
Supports high-power equipment such as RV air conditioners, refrigerators, microwave ovens, etc.
The solar panel is charged during the day and can be used freely at night
The battery pack is compact and does not take up space when installed in the locker
IV. Detailed DIY assembly process (illustration)
1. Receipt and accessories inspection
Check whether the battery cells, BMS, LCD display, insulation board, screws, cables and other accessories are complete
Confirm that the battery cell voltage is consistent (the difference is recommended not to exceed 20mV)
2. Install insulation board and battery cells
Separate every two battery cells with 24 fiberglass insulation boards according to the instructions to ensure safety without short circuit risk
Place 16 EVE battery cells horizontally for subsequent installation
3. Connect the PCB busbar and the copper busbar
Use the matching flexible copper busbar and screws to connect the positive and negative poles of each string of cells in sequence
Tighten the screws with a torque wrench to ensure good contact (5-6Nm is recommended)
4. Install active balancing BMS
According to the BMS manual, insert the sampling lines into the PCB busbar in groups (note the distinction between B1-/B1+/B2+…B15+/B+)
Connect the temperature sensor and stick it on the surface of the cell
Connect the BMS main line to the positive and negative poles of the battery to ensure that there is no error
