DATA VIEW MODE
The Data View mode of the TP1430C allows you to view various data collected within the mode and
throughout recently completed charging/discharging processes. You can reach the Data View mode
from the Setting Data Mode screen by pressing the MODE button once. From there you can use the
+/
– buttons to scroll through the available screens/menus accordingly.
Battery Internal Resistance
The TP1430C offers a quick and relatively effective means to measure the approximate Internal
Resistance (IR) of LiPo/LiIon/LiFe, NiCd/NiMH and Pb/lead-acid batteries as well as the individual
cells of LiPo/LiIon/LiFe batteries when the balance connector is connected to the balancer. However,
it’s important to note that while IR measurement from the TP1430C and other equipment readily
available in the industry can provide valuable insight into the performance of a given battery, the data
is not absolute. Even when using lab-quality, calibrated equipment to measure the IR of
cells/batteries there are many variables that will affect the IR of a battery at any given time including:
State of Charge (SOC):
The IR will read higher when the battery is discharged versus partially
charged versus fully charged. As a result you should always measure the IR of batteries at the
same SOC in order for the results to be relative and valuable to reference. We suggest checking
at full charge as this is the easiest SOC to achieve consistently with nearly all batteries.
Cell/Battery Temperature:
The IR will read higher when the cells/battery are cooler versus
warmer. This in mind you should always measure the IR of batteries when they are at the same
temperature if you would like to compare the relative results directly.
Physical Condition/Age:
The IR will read higher in cells that are physically damaged, swollen
and/or considerably aged and deliver less voltage and/or capacity under load accordingly. We
recommend checking the IR of batteries when they are new, and tracking their relative IR over
time as the battery ages. In the case of cells such as those featuring the Thunder Power RC
exclusive Generation 6 chemistry, the IR can actually decrease throughout the first 25-100+
cycles while often stabilizing for hundreds more cycles after.
Resistance of the Wire Leads/Connector:
Because the IR is being measured through the
battery and charger leads, it is possible for them to affect the measurement especially if the gauge
of wire is relatively small and/or there are poor connections. We suggest using the same charger
leads/connectors and ensuring solid connections at all times when making IR measurements to
compare relative results. This can be especially impactful when checking the IR of individual cells
of LiPo/LiIon/LiFe batteries through balance connectors as those connectors/connections can
often vary greatly in resistance.
Again, due to the myriad possible variables, IR measurement is not absolute and entirely indicative of
actual battery performance. However, if you take the time to ensure you check all batteries at the
same SOC, temp, with the same leads/connectors, etc. it is indeed possible to achieve relative results
that can be compared effectively.
Here is some additional information, including a few generic reference examples, regarding
approximate IR measurements/values:
A 3S 11.1V 2250mAh 45C battery will have approximately ½ the IR of a 6S 22.2V 2250mAh 45C of
the same make/model, condition, age, etc. This is because the 6S battery has twice the number of
cells, and approximately twice the amount of IR as a result. This is not exact as there will be some
