BATTERY CHECKER
BATTERY CHECKER
The Mega Meter allows you to check the individual cell voltages of a 2
cells-8 cells Lithium battery. The Mega Meter individually measures &
diagnoses the cell voltages of the multiple cells, the result is displayed
on the large liquid crystal screen. The Mega Meter replaces all of the
tedious measurement and calculations required in the past to determine
the overall voltage of the LiPo, LiFe & Lilon pack and the individual cell
voltages that determine the balance of the Lithium pack.
The Mega Meter now makes it possible to determine and verify the
detailed state of the Lithium battery.
A balanced battery provides a safer environment when flying. If you
know that your cell balance is out you can address the issue.
The prevention of deteriorating cells over time, will improve the
efficiency and stability of the Lithium battery.
When you connect the balance lead to the Mega Meter you must
ensure that both the Ground pin's for the balance connector and the
Mega Meter
go together. Different Balance leads have different wiring configurations
and some are colored.
The Mega Meter has 2.54mm pin intervals. If the connector on you
battery does not fit do not force the connector, obtain a suitable ad-
aptor lead from your hobby shop.

Serial voltage
Pack voltage of the whole battery (total voltage of all cells) is indicated
The number of serial cells
The total number of cells in the battery pack is indicated (6S as indicatec
in the picture 6 serial cells). This is the same as the cell quantity.
Remaining amount fuel gauge
The remaining amount gauge gives you a graphical bar graph display
of the status of the battery by graph and the balance of the cells by
graph. When the battery is fully charged the graph extends to "F" on
the right hand side of the LCD. As in the example you can see that the
battery is about 50% used. There are times when differences occur
between the remaining amount and the actual remaining amount.
These differences can be associated with the quality and use of the
battery and its cells. A battery that has always been charged with a
reputable balancer is likely to reproduce accurate readings on the
Mega Meter. A battery that has had a hard life full discharge and re-
charge with no balance charging is more likely to have discrepancies
between actual and shown results.
Cell balance gauge
The Cell balance gauge measures the difference between all cells that
are connected to the Mega Meter.
