Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: 2.2 0.3 = 7.3hours 2.2 0.3 = 7.3 h o u r s * The charge time depends on the battery chemistry and the charge current. [pdf]
[FAQS about How long is the appropriate discharge time for a lithium battery pack]
For the BMS to communicate correctly with the inverter the battery must be set to the correct Modbus protocol. This can be done on the battery settings page. The inverter manuals have a list of compatible batteries detailing their Modbus protocol and whether they use CAN or RS485 communications. [pdf]
[FAQS about Battery BMS communication connection]
The CMP technology is a traditional battery design approach where individual battery cells are grouped into battery modules, and these modules are then assembled into a battery pack. This hierarchical structure allows for a standardized and modular approach to battery design. [pdf]
[FAQS about Cmp lithium battery pack]
Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. [pdf]
