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. When to charge the battery pack?Disconnect 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. Over discharging the cells might damage them permanently. Note: Lithium batteries can become unstable, if not handled properly, resulting in heat or fire. Safety precautions and prior knowledge is advised. Warranty Terms:This battery pack comes with 3 year warranty from the date of purchase. Warranty is void if the pack/connector is physically damaged.
