The FMA PowerLab 8
and the CellPro 10XP have a "Storage Charge" feature.
We now know to use it. It is BVM's practice to not
leave the batteries fully charged for more than a few
days and to store them at room temperature.
feature of these modern chargers is their ability to
detect and record the internal resistance of each cell
in a pack. The "I.R." is the best measure of a
LiPo battery's capability to deliver Watts. We
record these numbers when the packs are first put into
use, then keep track of the number as we accumulate
flights. As the packs age, these numbers will
creep upward but should remain fairly even cell to cell
within a set of packs.
If you are using the
PowerLab 8 for fast parallel field charging, we have
found it helpful to occasionally slow charge the
batteries on the CellPro 10s or XP to verify the per
Tommy Wood is using:
Charger - (2) CellPro 10s
Storage Temperature - Room Temperature 75°-80°
Number of sets of ThunderPower - 3 sets
Current I.R. of cells - 1.2-1.5
Note: The CellPro 10s will
bring batteries up to storage charge after a flight.
It will not discharge the batteries.
