Product parameters:
Style 1: Standard Edition
Color: red
Input voltage: DC12V/DC15V
Output voltage: DC12V/DC15V
Product power: rated 24W (available 18W)
Standard version charging: about 1A.
Suitable battery: 7.4V-8.4V lithium battery.
No-load power consumption: 0.2-0.3mA <0.5mA
Indicator lamp: external two-color LED indicator lamp.
Product features: charging+battery boosting+switching+over-discharge protection
Working voltage: default 12V mode/input current should be ≥3A.
Battery capacity: 4-6Ah for slow charge and 4-12Ah for fast charge.
Charging voltage: the voltage range is 8.2-8.4V (average 8.3V).
Discharge voltage: When the battery is lower than 6.0V-6.4V, it will be automatically disconnected.
Path loss: the loss of FUSE and SS54 is about 0.4V-0.6V
Battery type: 7.4-8.4V lithium battery/support 18650
Charging method: trickle/constant current/constant voltage three-stage charging.
Charging current: 0.9A-1A charging current in fast charging mode.
SwitchINg threshold: switch to battery power supply when in voltage drops by 0.8V
Size: 50 mm * 20 mm (0.5 mm)
Support range of battery capacity: slow charge 4-6Ah, fast charge 4-12Ah, and the maximum capacity is 7.4V15Ah. *
This version of the charging chip has no battery capacity limit.
When the battery quality is excellent, you can try to match the fast charging mode with 20-30Ah.
Protection function and precautions:
INput protection: In input interface has reverse connection protection function.
Battery protection: battery interface over-discharge protection+short circuit protection.
Charging protection: Enable trickle charging mode when the battery is undervoltage.
Disable power supply: it is forbidden to connect with interference or unstable power supply.
Output protection: the output interface has short-circuit protection function.
LED protection: external LED, and the lead wire must not touch the power supply.
Chip protection: Turn off or restart when the chip exceeds 120 degrees.
Disable load: it is forbidden to connect motor or electromagnetic load.
Note: the battery wire must be thick, otherwise it will cause interference or insufficient output power.
Reminder: the correct assembly process should be:
first test the motherboard to ensure that it is in good condition, then weld the LED and the power cord at both ends,
finally weld the battery cord and connect the battery, and then power on the test!
Note : The power of external power supply should be greater than (load power+charging power).
About power:
The standard version, for example, has a peak power of 30W (when the battery is fully charged, it is only allowed to test for 3-5 seconds), a rated power of 24W (when the battery is over 50%,
it is allowed to test for a few minutes after being fully charged) and a valley power of 18W (when the battery is about to run out, it is allowed to be used for a long time).
Because the battery cannot remain fully charged during use, users can only use valley power, that is to say. But the actual power can’t exceed 18W, otherwise there is the risk of overheating and restarting.
As for the power of 24W, when the battery is fully charged, it can only be used for a few minutes or dozens of minutes, but this power can’t be used for a long time!
Unless you add a temperature-controlled fan to cool the motherboard, you can continuously load 24W power for a long time with good heat dissipation effect.
