Features:
•High Quality Intelligent smart charger (Manufacture part#KP4818CL) designed for
SLA (36V-48V, 18-24Cells), Li-Ion/LiMnNi (29.6V-51.8V, 8-14Cells), LifePO4 (38.4V-
51.2V, 12-16Cells) Battery pack
•Adjustable Charging voltage from 29.6-58.4VDC
•Must select charging voltage correctly based on battery used below
oLi-Ion / LiMnNi = 4.17V / cell
Ex. Charging voltage for 51.8V (14Cells) Li-Ion/LiMnNi =
4.17V x 14 = 58.38V
oLiFePO4 = 3.55V / cell
Ex. Charging voltage for 51.2V (16Cells) LiFePO4 =
3.55V x 16 = 56.8V
oSLA = 2.43V / cell
Ex. Charging voltage for 48V (24Cells) SLA = 2.43 x 24 =
58.32V
•Charging Stage: CC (Constant Current) --> CV (Constant Voltage) --> Floating
•Switch-Mode Technology
oConvert from AC input voltage to DC charging voltage 1677 times faster
than traditional linear charger
oUnit will be smaller, lighter and higher efficiency than traditional linear
charger
•Built in cooling fan to ensure charger long service life
•Input AC power: World-Wide 90-132VAC / 200-240VAC , 47-63Hz, USA AC plug
oFor international use, please click here to order AC plug adaptor
seperately
•Cut-Off Automatically when the battery is fully charge
•Safety protection
oOver Current & Over Voltage protection
oShort Circuit protection
oReverse polarity protection
•Charging Voltage: 29.6-58.4VDC
•Charging Current: 18.0A +/- 0.5A
•Max Power output: 1200W
•Charging time:
oLi-Ion / LiMnNi Charging time = (1.5 x Ah rate of the pack) / charge
current.
oLiFePO4 Charging time = (1.41 x Ah rate of the pack) / charge current.
oSLA Charging time = (1.2 x Ah rate of the pack) / charge current.
•Battery pack Capacity:>= 18Ah
•Stylish Aluminium Enclosure
•Built in 2 unit of LED indicator
oPower ON: LED 1 = Red
oCharging (Constant Current): LED 2 = Red
oCharging (Constant Voltage): LED 2 = Red
oFully charger: LED 2 = Green
•Charging terminal : 4' long 8AWG wire 1.9" x 1.5" x 0.6" Standard Anderson
connector

•Dimension (LxWxH): 260mm(10.2") x 175mm(6.9") x 90(3.5")
•Weight: 9.9 lbs (4.5kg)
•High Efficiency: 85-95%
•MTBF (Mean Time between Failure): 30,000 POH (Power on Hour) = 10 years of
everyday operation of 8 hours
•CE listed
•Operating Temperature: 14F(-10’C) ~ 113F(45’C)
Charging instruction: (please follow the instruction below to
charge a battery pack)
•Connect the AC power to charger (LED1 - Red)
•Adjust the voltage to the max voltage you need for your pack
(see above on cell peak charge voltage)
•Connect the battery pack to the charge, the charger will start
charging:
oNote: you cannot measure the output voltage of the
charge. The charge will apply the correct voltage once it
sense the presence of the battery pack.
oYou must connect the battery pack to the charger within 5
minutes time frame. If not, the charger will not charge
your pack
•If the charger still does not charge your pack, disconnect the
battery pack from charger, remove AC power and wait a min of
30 minutes to try the above process again! This is necessary to
discharge the capacitor inside the charger.
Charging cycle:
If the LED1is ON ( Red ), it shows that input power is ON.
The explanation of the charging cycle is as following.

*** See Stage 2description below
Stage 1: Constant Current Mode (CC):
The charger changes to constant current 18A+/-0.5A. When the
battery voltage reaches up to 29.6-58.4V (Based on voltage selection),
the charging stage changes from CC (Constant Current) to CV
(Constant Voltage) mode.
Stage 2: Constant Voltage Mode (CV):
In this stage the voltage of each cell in the battery is
equalized.The charger holds the battery at 29.6-58.4V (Based on
voltage selection) and the current slowly reduces.
