Pololu 2176 - Battery Balancer & Watt Meter

When you connect this watt meter between a power source and its load, it provides readings of several useful parameters:

• Current (A)
• Voltage (V)
• Power (W)
• Cumulative current (Ah)

Both the source and the load ports are female “Deans Ultra”-style T connectors. A short male-male cable is included for use with the source connection.

The unit can also serve as a battery checker and balancer for lithium polymer (LiPo), lithium iron phosphate (LiFe), and lithium ion (Li-ion) battery packs. Balancing a battery pack ensures that it has an equal charge in each cell and prevents a weak cell from limiting the capacity of the battery. 2- to 6-cell packs with 2.5 mm JST XH-style connectors are supported via an included socket adapter.
