Charging a pack
As shipped from the factory, the Multi4 Charger is equipped with 20 User Presets optimized for
common battery types, plus five Empty Presets. In many cases, you can simply select the User
Preset that matches the pack you want to charge, connect the pack and start charging.
User Presets cover LiPo, Li-Ion, A123, NiCd, NiMH and Lead Acid chemistries paired with
commonly-used charging strategies. (If the User Presets aren’t quite what you need, see the in
-
structions beginning on page 6.) The charger also includes a Preset Library containing up to 50
presets. A Library Preset is like a User Preset, except that it must be loaded into the User Preset
bank before it can be changed and used for charging (see “Loading a Library Preset,” later).
1. Connect the charger to a 10V to 16V (maximum), 5A power source.
2. After the Welcome screen (Cellpro Multi4) times out, you’ll see the Preset Menu.
Tip:
More information about the display —and how to navigate it—is provided on the
next page.
3. The Preset Menu displays last User Preset you used. If this is the User Preset you want to use
to charge the pack, go to step 4.

Press the
Mode
button until the User Preset you want is displayed (see “Factory-installed
User Presets” for descriptions). (If you see
EMPTY PRESET
, press the
Mode
button to go
back to the beginning of the list.)
Tip:
Quickly press and release, press and hold, then release the
Mode
button to re-
verse the sequence of items being displayed in the Preset Menu. The tone indicates
which direction you are going: high tone for forward, low tone for reverse.
4. Connect the pack to the charger.
5. If Auto Start is OFF (factory default), press and hold the
Mode
button. This displays the
Operations Menu, which cycles through several screens. When you see
START
, release the
Mode
button. The display will briefly show
CHECKING PACK
.
otherwise
If Auto Start is ON (see page 7), go directly to step 6.
6. The next screen displays the preset’s chemistry (for example,
LiPo
) and prompts you to
verify it is the same as the pack’s chemistry (which should also be, for example, LiPo). This
safety check is your chance to prevent charging if the preset and pack don’t match.
