The positive is passed directly to the load. So, one end of this wire needs to be connected to your main battery positive connection and the other side goes to the charge/discharge connector. This wire needs to be just as thick as the B- wire, and you can attach it to the battery pack using the same trick described for the B- connection.
$begingroup$ You can always connect two battery packs in series. The problem is to keep the stronger cells from reverse-biasing the weaker and destroying them. In your case, the thing to do is provide a simple voltage-sensing circuit for each battery pack, and if either pack gets a voltage too low, you MUST turn off power to the load.
So, it''s important to have some sort of method for balancing the cell groups in a lithium-ion battery pack. Remember, your lithium-ion battery is only as strong as its weakest link. So, even if just one single cell group has a lower voltage than the rest of the pack, the battery will cut off when that cell group reaches the cut-off point.
The significance and purpose of soft pack lithium-ion battery packaging are to completely isolate the inside of the cell from the outside using a high barrier flexible packaging material, leaving the inside in a vacuum, oxygen
If you can put it next to the foil you will measure the battery temperature better (less thermal resistivity from heatshrink that normally comes on the li-ion packs). Most applications measure battery temperature for thermal runaway reasons so if the battery is getting hot, its going to get hot everywhere.

If you chose to replace batteries in your pack with a different kind of lithium battery (not recommended) you should use packs that are similar in capacity and power capability as the cells you are replacing. That means that you packs can''t be any bigger then four cells deep or you won''t be able to weld the cells in the middle. For most
If you can''t find a 3-wire replacement, the best solution would be to measure the resistance between yellow and black at room temperature and add the correct NTC across these pins on the new pack (it will probably be 10 kOhms). If you try to use a pack without an NTC, the charger will probably severely limit the battery charge current.
The battery type is 1ICR19/65-2, meaning that the battery consists of 2 Lithium-ion cells which are put in parallel. Each cell has a nominal voltage of 3.7 V and a capacity of 2200 mAh.
