+===== BASICS ABOUT LIPO BATTERIES =====
 ==== Connectors ====
+The LiPo batteries usually have two connectors, the main connector and the balance connector:
+=== Main Connector: ===
+Provides the main power for the battery when charging and drains the power when discharging. It is directly connected to the electronics.

+**WARNING:**
+Some small batteries have two main connectors, one of them can be confused with a balance connector and produce a short-circuit to the charger (white connector in the picture).
+----

+=== Balance Connector: ===
+This cable is plugged into a battery charger and provides the information needed to keep the voltages between cells almost equal.

 ==== Battery's Specs ====
-  * Voltage
-  * cell count
-  * capacity
-  * discharge rate
-  * charge rate.

+{{:tutorials:battspecs.jpg?300 |}}
+=== Cell Count: ===
+This number indicates the total of cells that a battery has.
+=== Voltage: ===
+The nominal voltage of 1 cell should be 3.7V. It can go up to 4.2V and as low as 3V, but they should never exceed this limits.
+=== Capacity: ===
+Is the amount of energy that the battery can store, measured in miliamps hours (mAh). With a 1000mAh battery, the energy will last 1 hour with a continuous draw of 1A or 1000mA.
+=== Charge and Discharge Rate: ===
+This number is usually followed by a "C" in the battery package. It indicates the maximum rating at which a battery can be charged or discharged.
+With a 1000mAh battery and 2C, the maximum current you can pull is (2*1000mAh) = 2000mAh without damaging it and it will last half the time. In the other hand, the maximum charge current is (2*1000mAh) = 2000mAh and it will be charged in half the time.
