Note: (Important things are repeated three times!)
Connect the battery positive and negative can not be reversed (Red Positive + ; Black negative - ), the reverse will be bad, no warranty! The reverse will be bad, no warranty! No warranty!
Instructions:
The first step: the charger should not be connected to the battery, turn on the power, adjust the voltage knob to adjust the voltage, refer to the voltage display above the display screen, (4S lifepo4 battery 3.65v*4=14.6 volts, 3S li-ion lipo battery 4.2v *3=12.6V), adjust to the voltage you need.
Step 2: Adjust the current to a minimum. After connecting the battery, adjust the current from small to large and adjust to the current you need. (In the charging process, it is not allowed to adjust the voltage knob again, otherwise overcharge or undercharge will occur)
If the voltage is displayed, the voltage you set, the current becomes zero, and it is already full.
Lead-acid battery charging precautions:
Lead-acid batteries do not support high-current charging, and should be charged with a current of 1/10 of the capacity. For example: a one-hundred lead-acid battery, you need to charge with 10 amps! The time must be 8-10 hours, the time is too fast, the current is too large, it will damage the battery. The lead-acid battery charging voltage is about 14.4 volts. The battery manufacturers are different. The voltage is slightly different. The instructions on the battery label shall prevail! Can also Baidu query!
Note: The goods are handmade, the appearance may be slightly scratched
Input voltage: AC 100v/110v --220v/250v
Input power: the new version750W. Old version 675W
Output voltage: DC constant voltage meets 11V-14.8V (suitable for 3S Li-ion Lipo and 4S Lifepo4)
Output current: DC constant current is adjustable to 1-53A. Old models 1-50A (only constant current and constant voltage can be used as charger)
Protection method: After the positive and negative poles are short-circuited, stop the output. (The current knob is adjusted to the minimum to the off state, and then restarted to resume)

Lithium battery charger DIY S350-27 repair experiment voltage regulator adjustable power supply 4-bit high-precision meter
Color Classification:
0-50V
0-95V
Power supply introduction:
This power supply is modified from the second-hand original s350-27. The original 350-watt 27 V13A switching power supply has been modified to have adjustable voltage, adjustable current, and constant current and constant voltage.
Voltage: 0-95V, Current: 0.8-12A, since the original power supply has a rated power of 350 watts, and 27 volts can use up to 13A, the modified alignment increases the voltage. According to power = voltage x current, it is recommended to use 50V full power 7A, and 80V full power 5A use, can not be used for a long time with overpower.
Size: 26X11.5X5 cm,
Weight about 1.2KG,
All aluminum body
The consumables are made of 4-digit high-precision meter head, mA-level current display (10A range, the smaller the range, the higher the accuracy), precision multi-turn potentiometer (10K10 turns, WXD3-13-2W), bakelite potentiometer knob, beautiful and generous Acrylic panel, pure copper binding post, temperature control switch, capacitor, resistor, 12V power supply board, aerial plug-in cable, waterproof connector, indicator switch, other connecting wires and heat shrinkable tube.
Scope of application: suitable for power supply of DC equipment below 95 volts, or charging of lithium batteries and lead-acid batteries below 95 volts, notebook maintenance, induction cooker maintenance, mobile phone maintenance, inverter maintenance, etc. Senior engineer maintenance of precision circuit current needs to be adjusted from O, please make special remarks.
