Installation

NDS Energy SCS2 Universal Battery Smart Charger 02

CONNECT THE DEVICE CLAMP CONNECTORS (OR THE RING CONNECTORS) TERMINALS TO THE BATTERY
The Red terminal to the positive battery pole and black terminal to the positive battery pole. Switching the connection polarity on the battery poles will stop the charge and SMARTCHARGER will light up the error led!
CONNECT SMARTCHARGER TO AC POWER SOCKET.
IF POWER INDICATOR LED IS ON, SMARTCHARGER IS READY TO CHARGE.
SET THE CORRECT CHARGING CURVE PRESSING THE MODE BUTTON (SCS4, SCS8)

The Charging curve depends on battery technology and speciﬁcations.
See the curve description at Page 9.

Follow this steps to start the charge:

Connect the SMARTCHARGER to the battery (P.5), then plug the AC power socket. The power status led will turn on.
NOTE
If the ac power socket is connected before connecting the clamps to the battery, the error led will be turned on
Connect the clamps to the battery then push the mode selection button t MODE o restart the process.
If everything is ok SMARTCHARGER SCS2 will start charging directly.
For SMARTCHARGER SCS4 and SCS8 use the “MODE” selection button to switch between auto, motorcycle, AGM, Lithium, charging curve. When a charging curve is selected the process will start.
SMARTCHARGER will check battery status before to start. If the battery is ok the charge will start normally (step 5), if not the device will try to recover the battery (step 4).
If there’s something wrong with the battery SMARTCHARGER will try to recover it and the rescue led will light up.
Rescue can take 30 to 120 minutes.
Charge will turn to normal charge (step 5) when the battery is recovered. If battery can’t be recovered the error led will be light up
If everything is ok the charge will start and the charging led will light up.
The full charge / maintenance led will light up when the battery is fully charged and now is in trickle charge: If the voltage drops down SMARTCHARGER sends current to the battery. SMARTCHARGER can be connected for months without any trouble.

NOTE
If the Lithium battery (LiFePO4) is deeply discharged and the function UVP (under voltage protection) disconnects the battery to prevent damages, the SMARTCHARGER will be not able to charge. In fact this protection interrupts the connection between battery and chargers/appliances and the SMARTCHARGER will detect no battery.
To solve this problem press the “MODE” button for 5 seconds and release until the “LITHIUM LiFePO4” led light will be turned on, after that the charge will start normally.
Charging curves
The new “OPTICHARGE” ﬁrmware engineered by NDS software team optimize the battery charge according to the battery technology using optimal charging parameters and constantly checking current and voltage levels to let you have always ready to go and healthy batteries. With OPTICHARGE you will have the best charging experience ever created by NDS, the easiest way: just p l u g t h e d e v i c e i n t o t h e p o w e r s o c k e t , SMARTCHARGER will do the rest!

Charger 06

SCS4, SCS8 – PHASES DISCUSSION

PRELIMINARY CHECK| Battery status Check.
Charge will not start with voltage under 2.0V and more then 15,5V
RESCUE| For deeply discharged battery: current will be 200-400mA at 16V for 5 seconds until voltage reduces to 14V (2 hours max timeout)
SOFT START| If battery voltage is between 2.0V–6.0V a limited current is delivered (0,8A) to re-activate the battery elements, until voltage rises above 6V (2 hours max timeout)
PULSE CHARGE| If battery voltage is between 6.0V-10.5V, current will be at 0.8A and 2A for 5 seconds alternately (4 hours max timeout)
RECONDITIONING| After Pulse charge, If battery voltage reaches 10.5V–12.0V smartcharger will constantly deliver 2A current to charge the battery until it has risen over 12.0V. This stage will not be carrying over 8 hours, otherwise the battery is classiﬁed as defected.
BULK CHARGE| If battery level has reached 12.0V-13.6V. A constant current will charge the battery until it has reached 80% of the capacity.
SCS4: 1A (motorcycle mode), 4A (car mode), 4A (AGM mode).
SCS8: 2A (motorcycle mode), 8A (car mode), 8A (AGM mode).
ABSORPTION CHARGE| If battery level is between 13.6V-14.4V (14.7V for agm), Smart charger will switch to Constant voltage mode: output current will automatically adjust as according to the raise of battery voltage. The charge will stop at 14.4/14.7V. Smart charger will turn on the Full charge icon led if the current reduces to: current <0.5A (motorcycle mode), current <0.8A (car mode), current <0.8A (AGM mode)
FINAL CHECK| Battery voltage is monitored for 1 minute. If voltage has a dramatic drop down under 12.2V, the battery will be classiﬁed as exhausted and the error led will turn on. If voltage can be retained at 1 minute, then the Maintenance mode will start.
MAINTENANCE| Battery maintained at 13,8V, a proper work level to be kept always ready to go.
If voltage drops below 12V, smart charger will restart from bulk charge
PRELIMINARY CHECK| Battery status Check.
Charge will not start with voltage under 2.0V and more then 14V
---|---
RESCUE| For deeply discharged battery: current will be 200-400mA at 13,8V until voltage will be >11,5V (2 hours max timeout)
CHECK| If battery voltage＞10.8V, smart charger move to next step
BULK CHARGE| If battery level has reached 13.8V. A constant current (SCS4: 4A, SCS8: 8A) will charge the battery when the current reduces to 0,8A
ABSORPTION CHARGE| If battery level is between 13 . 8V-14 . 4V, Smartcharger will switch to Constant voltage mode: output current will automatically adjust as according to the raise of battery voltage. The charge will stop at 14.4V. Smartcharger will turn on the Full charge icon led if the current reduces to 0,8A
FINAL CHECK| Battery voltage is monitored for 1 minute. If voltage has a dramatic drop down under 12.2V, the battery will be classiﬁed as exhausted and the error led will turn on. If voltage can be retained at 1 minute, then the Maintenance mode will start
MAINTENANCE| Battery maintained at 13,8V to be kept always ready to go. Routine is: 2 minutes charge and 2 minutes pause for 12 hours, then stop.
If voltage drops below 13,3V, the maintenance mode routine will restart.
If voltage drops below 12V, the smart charger will restart from bulk charge
