Continuous current is dependent on cell temperature. If you stay in the cooler range you can draw more current form the cell.
Module Info
These are easy to handle 24V battery modules built using INR21700M48 cells above. The ribbon cable is held on by bolts, removing it and adding your own BMS harness with ring terminals will be easy. It is possible to break it down into smaller groups in series, but it looks like the end pieces are unique, so if you break it down to 5s or 4s, you might not have an easy way of assembling the remaining components into a separate module. There are gaps in between the cells for air cooling. Incorporating air cooling into your own build will be easy if you intend to use them under high currents. The modules interlock with each other in a sliding action to create a sturdy complete pack if you are planning on buying multiple of this item and use them as is. We also have a busbar that we could provide upon request that will series together modules.
For Cell Harvesters
The 21700 cells are NOT welded, disassembly is extremely easy. The cells are compressed and spring loaded through a patented design. One purchaser has made a very detailed breakdown of a similar module that you will find very useful. You can find it here.
