15 A123 1100 mAh Non Balanced. Optimized for non-balance charging A123, 1100 mAh
battery packs (node wires not required on the pack). Fuel Table is optimized for
this specifi c battery type and capacity. Selectable charge rates include 1C, 2C, 3C
AUTO or 0.25A to 4.0A manual. Optimization is for faster charging with termination
settings of C/10 and max of 15 min timeout for C.V. mode. This preset is not
capable of charging every cell in the battery to exactly 100% because it does not
have access to individual cell voltages. Imbalance will be present at the end of
charge; however, A123 cells are not as sensitive to this problem. Nevertheless,
charging A123’s using the balanced charge preset(s) is recommended whenever
possible. This preset may also be used for LiFePO4 type batteries which have
similar charge characteristics. When using LiFePO4 batteries, Fuel Gauge readout
may not be accurate and AUTO charge rate may be higher or lower than expected.
Default charge rate setting is 3.3A manual. Because this preset is not restricted by
the node connector, it can handle 1-5 cells of this battery type only.
16 A123 All Cpcty Storage Charge. Special A123 preset designed to storage charge a
discharged battery up to 3.35v per cell. This preset will only work if the battery is
below the storage charge voltage when connected. Manual charge rate setting is
required when using this preset and ranges from 0.25A to 4.00A. Default setting is
3.0A.
17 NiCd Fast Charge with Trickle. Basic NiCd Fast Charge with Delta Peak Cutoff and Trickle
Charge. Requires manual charge rate setting of between 0.25A and 4.0A, with
default value of 1.0A. Can charge from 1 to 12 cell packs. Fallback default setting
is 8mV. Trickle charge rate is 1/20C of the charge rate setting. Charge will timeout
in 4 hrs if peak is not reached. Trickle charge timeout is set for 1 Day.
18 NiMH Fast Charge with Trickle. Basic NiMH Fast Charge with Delta Peak Cutoff and Trickle
Charge. Requires manual charge rate setting of between 0.25A and 4.0A, with
default value of 1.0A. Can charge from 1 to 12 cell packs. Fallback default setting
is 5mV. Trickle charge rate is 1/20C of the charge rate setting. Charge will timeout
in 4 hrs if peak is not reached. Trickle charge timeout is set for 1 Day.
19 NiCd/NiMH 24 Hr Trickle Charge. Basic NiCd or NiMH 24 Hour Trickle Charge preset.
Requires manual charge rate setting of between 5 mA and 300 mA with default
value of 100 mA. Can charge from 1 to 12 cell packs. Trickle charge timeout is set
for 2 Days.
20 Lead 12v SLA or Gel Cell. Basic Pb (Lead) preset for charging 12v SLA or Gel Cell batteries.
Requires manual charge rate setting of between 0.25A and 4.0A, with default
value of 4.0A. Charges 12v battery only. If you require a 6v charge, this preset is
available in the charger library and can be copied into the user bank (see manual
for instructions). Charge will timeout in 16 hours even if end charge voltage setting
of 14v is not achieved.
21 EMPTY PRESET. May be populated with any preset from the charger library or the FMA PC
library.
22 EMPTY PRESET. May be populated with any preset from the charger library or the FMA PC
library.
23 EMPTY PRESET. May be populated with any preset from the charger library or the FMA PC
library.
24 EMPTY PRESET. May be populated with any preset from the charger library or the FMA PC
library.
25 EMPTY PRESET. May be populated with any preset from the charger library or the FMA PC
library.

Loading a Library Preset
The Multi4 Charger is equipped with 50 Library Presets. A Library Preset (which you can’t
change) is a starting point for creating your own User Preset (which you can change). FMA
confi gures Library Presets with optimal charge characteristics for a variety of battery chemistries
and charging strategies. You can replace an existing User Preset with a Library Preset, or—if
your charger has less than 25 User Presets installed—you can create a new User Preset from a
Library Preset. After you load a Library Preset into a User Preset slot, you change the charge
rate as described earlier in this manual. When using the CCS, you can confi gure up to 80 charge
parameters in each User Preset.
1. Navigate to the Preset Menu.
2. If the User Preset you want to replace with a Library Preset is displayed, go to step 3.
otherwise
Press the Mode button until the User Preset you want to replace is displayed.
or
If the charger has less than 25 User Presets, press the Mode button until you see EMPTY PRE-
SET (this will enable you to create a new User Preset).
3. Press and hold the Mode button. This displays the Operations Menu, which cycles through
several screens. When you see PRESET LIBRARY, release the Mode button.
4. The display now shows the fi rst of several Library Presets. Press the Mode button to cycle
through available Library Presets (the list wraps around).
Tip: Quickly press and release, press and hold, then release the Mode button to re-
verse the sequence of items being displayed in the Library Preset Menu.
5. When you see the Library Preset you want, press and hold the Mode button, then release it.
6. You are prompted to confi rm the replacement. Press the Mode button to switch between con-
fi rming the replacement (>Y) or denying the replacement (>N).
7. When you have selected the desired response to the prompt, press and hold the Mode button.
If you selected Y in step 6, this copies the Library Preset to the Preset Menu, where it replaces
the selected User Preset or creates a new User Preset.
8. You are returned to the Operations Menu. Release the Mode button when you see the opera-
tion you want.
Open architecture presets
The Multi4 Charger can be described as being “preset driven.” All major aspects of its operation
are defi ned as parameters at the preset level. The fact that you (for the most part) can set these
parameters introduces the concept of “open architecture presets.”
As an example of how preset parameters affect the charging process, each Auto mode preset
includes a Fuel Table unique to a specifi c battery chemistry. When you select a User Preset for
the REVO Red brand, for example, you are also selecting a Fuel Table tailored for that brand. The
charger uses the Fuel Table to adjust current to maintain the specifi ed C charge rate. Given a
brand-specifi c Fuel Table, the Fuel Level display and Auto charge modes are highly accurate.
When preparing to charge a pack, the fi rst step is to fi nd the appropriate User Preset. If one
doesn’t exist, you might be able to create a User Preset from the closest Library Preset. Or you
might select a User Preset from the library available in the Charge Control Software (which enables
you to load, select, backup and share presets). You can even create a new Fuel Table for any Li
chemistry by starting and recording a 1C charge (temporarily using a manually set current), and ap-
plying the table to an existing User Preset.
FMA technicians will continually update the presets library, which is included each time you up-
date the Charge Control Software. This library will be supported far into the future as new battery
brands and chemistries are introduced.
