8-cell lithium iron phosphate battery pack charger, 1.5A at 25.6 volts, with slow-start function and fuel gauge

More lithium iron phosphate battery chargers

8-cell Llithium iron phosphate pack charger

This is a charger for 7-series LiFP battery packs, nominally 25.6V (8 x 3.2V), which charges at 29.2 volts (8 x 3.65V). The bulk charge current is 1500 mA. It is a multi-stage Li-iron LiFePO4 recharger with universal AC input. Includes a slow start feature and a 4-segment fuel gauge.

These are state-of-the-art battery chargers that can be used on-demand, or left permanently on the battery for maintenance. The slow-start function helps battery cycle life, especially with deeply discharged batteries. The charger is fully isolated from the mains, has universal AC input, and a removable AC cord (included). Will accurately lithium-iron-phosphate packs.

General Information

Model	PST-G100-24F8
Function	25.6V (29.2V) Volt battery charger for Li-iron phosphate 8-cell batteries

Technical Information

Rated input voltage	90-264 VAC, 50/60 Hz
Battery type	25.6V nominal 8-cell LFP battery
Input Frequency	50-60 Hz
Battery voltage	25.6 volts nominal
Battery size	3 AH to 30+ AH packs
Charger type	Constant Current/ Constant Voltage precision charger
Charging current	1.5Amps or 1500mA peak charge
Charging algorithm This is the "European" charge algorithm that does not float charge the battery at the last stage, but still keeps it maintained. (see the graph below)	Constant current/constant voltage
	Stage 1 slow start, pre-charge function for deeply discharged packs
	Stage 2 bulk charge stage. 1.5 amps is applied to the battery until the voltage rises to 29.2 volts
	Stage 4 constant voltage state until the charge current falls to 400mA
	Stage 5. The charger turns off.
Output power	36 W peak
Output voltage	29.2 volts maximum during charge
Size	170 X 71 X 51 mm, 6.7 x 2.75 x 2.0 inches
Style	Set top
Environment	-20°C to +50°C operating, -40°C to +70°C storage
Weight	400 grams, 0.9 lbs, 14 oz.
Vibration, Impact	5mm, 50Hz, 600 Seconds, 1 meter drop 3 times
Output options included	5.5 mm OD x 2.1 mm ID barrel, center positive More barrel connector adapters available separately, see below
Protections	Over Voltage Protection, Output current protection, reverse polarity protection (auto-clearing), short circuit protection (auto-clearing)
Efficiency	>80%
Safety	TUV CE marked, designed to EN60950, GB4946, UL1950, certified and marked TUV
HiPot, ESD	Hi-Pot 3000 V, 1 minute, ESD 8000V
MTBF	30,000 hours by MIL-STD calculation
Cooling	Natural convection, no fan
LED Indications	Power on, but no battery connected	Power LED red
	Slow start	The lowest green light is the only one on.
	Charging	Charging lights lit to show the state of charge
	Charged	All four green LEDs are on
	Reverse polarity, or shorted output	All lamps flash
	No battery connected	Red light is on, but no green LEDs
	Red light slowly pulsing	The battery voltage is higher than the charge voltage so the charger is sleeping until the voltage drops low enough to accept charging
