Blog EVPower
Always check the technical specification of the cells and other products BEFORE the installation. Check the voltage, polarity, dimensions, mechanical shape, the proper design of the terminals, etc. Be sure to report any strange conditions to us BEFORE the operation and installation of the cell or other product. We will be happy to provide support for any irregular situation. Learn more at the

". "Changing the number of cells for BMS123-Smart

Blog EVPower
Question: I have BMS123-Smart with 4 cells. When I add more cells, they are not recognized by the system. Answer: You need to change the setting of the BMS123-Smart to match the number of the cell that will be recognized. See the . This setting allows changing the size (rating) of the current sensor and the number of the cells in the pack. The setting is recorded by the opening of the switch No 8, as the manual explains: Set all switches below in the right positions for current sensor and number of cells and toggle switch 8 ON and OFF again. The hidden settings are now stored in the BMS. Set the switches back in the original positions. Please be aware it could be necessary to follow the current sensor calibration procedure again.

". "The condition of the safety valve

Blog EVPower
Question: When making the regular inspection of the battery pack, I noticed that there is some salt-like powder around the safety valve. How does it come about? Answer: 1. New cells All cells shipped by GWL/Power are visually inspected before delivery. They are delivered in 100% perfect condition. If you receive a new cell right from the shipment and there is some dirt or moisture around the terminal, you should contact the shipping agent and during the delivery. You can also prior using the cell. 2. Used cells – regular maintenance As concerns cells that are used for some time already, these cells should be inspected regularly every few-hundred cycles. . There should be no leakage or substance around the terminals or around the safety valve. We suggest cleaning the cells every time the inspection is made. You can use a lightly wet cloth to clean the outside of the cells.

". "How often should I check my cells (or my battery pack)?

Blog EVPower
The answer depends on the type of application. See some examples. 1. Simple installations Simple installations with one battery (12V) or with just a few cells do not need any special inspections. If you have a SMB to handle the protection of the pack, you can just monitor the voltage level. This kind of pack should be inspected once or two times in a year. Or perhaps each time after a longer pause in usage. Note: do not forget to if not using the pack. The pack should have a dual protection, . 2. Advanced installations More advanced installations (typically with 8 cells and more) should be monitored regularly. It is recommended that the inspection of the pack is performed in these intervals (ie, after number of discharge / charge cycles):

". "Determining the size of cells based on current and operation time

Blog EVPower
FAQ: Determining the size of cells based on current and operation time Question: I need a battery pack to supply 60 Amp continuously for 8 hours. What size of the battery do you recommend? Answer: The above table shows the size of the battery packs (in Ah) based on the 100% DOD (depth of discharge) and 80% DOD. is typically used according to the specification of the manufacturer to reach the optimal life span (cycle life) of the battery pack. For a pack running for 8 hours at 60 Amp, at 80% DOD, the capacity of the cells should be at least 600Ah. Tip: you can assemble the 600Ah cell using the or 2x300Ah single cells .
