To charge the battery just connect it to a female DC barrel connector and provide 8.4V (4.2V per cell) to the positive pin and ground to the negative pin. Monitor the increase in the voltage with time and stop charging after the pack has reached more than 8.2V. Using RPS to charge the cell will provide better control and understanding. \u003c\/p\u003e\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eWhen to charge the battery pack?\u003c\/strong\u003e\u003c\/p\u003e\u003cp data-mce-fragment=\"1\"\u003eDisconnect the cells from the load when the voltage has dropped to 6V (3V per cell) or below and charge them before you can use them again.
