jest! Not really. A prototype device from Sid Kaufman
(SLK Electronics - the ElectriCalc people) that
found its way to the Battery Lab that does just
that. We found some minor glitches in the pre-production
sample and worked them out with Sid. Sid replaced
this with another unit; making some code adjustments,
and the problem was resolved.
LiPoDapter, as it is called, is connected between
your LiPo pack and just about any charger with output
voltage and current needed for the LiPo you want
to charge. It conservatively counts the number of
cells. While you are setting it up, the green LED
blinks number of cells. Should the number of cells
indicated be low you simply tap the programming
button to add a cell.
you have verified the number of cells you then hold
down the program button for 5 seconds until the
red LED comes on, blinking the number of cells to
confirm your setting and indicating you are connected
to the charger. Then you set your charger to the
desired charge current.
the cut-off voltage limit (4.15-4.2 volts/cell)
is reached the red LED stops blinking and the green
LED comes on indicating the charge is complete and
the charger is disconnected.
found it worked on any Ni-Cd/Ni-Mh charger I had
in my collection - even the Alpha 4 (on N function).
The unit is packaged in 6-mil clear heat shrink
and is available in either a single unit or a dual
unit for charging two LiPos at once.
The units tested do have a drawback. The LiPoDapter
has what we could call a hard cut off once it reaches
the cutoff voltage. If you are charging at higher
rates, such as 1C recommended by most manufacturers,
the LiPoDapter charges the pack only about 70%.
Most Lipo chargers employ a tapering current as
they approach cut off, what we would term as a soft
cut off. If you use a lower charge current you will
get to a higher level of charge, but that will take
