Bảng Mạch Sạc Pin Lithium 1a Tp5000

Brand letter dejia electronic; model tp5000 charging board

Product parameters:

Tp5000 lithium ion battery iron phosphate lithium battery 1a current 4.2/3.6v
Function: charging lithium battery and iron phosphate lithium battery.Full of stop.Red and green double light indicator.
Size: 21.5x14.5x4.2 mm
Usage: tp 4056 4057 charging board is the same.
- lithium batteries need only 5v power supply, output b+b - battery.Charging red light, full stop, charging the green light.
- for lithium battery 3.6v phosphate iron, only soldering iron is required to open tin points between two solder plates.The power battery connection method is the same as mentioned above.If you need to recharge 4.2 v lithium battery, use the solder solder solder to connect back.



Product description:

Advantages: switch-pressure-relief mode, higher efficiency than linear charging circuit, and much less heat.Charge current 1a, in the constant current charge to maintain 1a.No extra heat dissipation is required to reduce the effect of heat on charging current.Reduce charging time.Optional ordinary lithium ion lithium polymer battery or lithium phosphate iron lithium battery, just one jump line can change the setting.
Parameters:
Input: 4.5-9v
Output voltage: 4.2v/3.6v positive and negative 1% (circuit board default lithium ion battery 4.2v)
Output current: default 1a
After the efficiency test, it will be described in detail that if the buyer tests the efficiency and does not recommend testing the battery terminal voltage, please note skipping the rs sample 0.1 ohm resistance test. the input of power into the test is close to the circuit board and reducing the length of the connection will have an impact on the efficiency test.Voltage current test recommends that a series of ammeters with precision should not be read directly.The current test can be directly connected to the battery's positive pole, only to ensure that the battery is less than 3.9v using a large number of ammeter tests.

Characteristics:
The whole edition uses precious metal ceramic capacitor, x 7r temperature characteristic, performance+safety+stability far more than tantalum capacitance!

Copper belt 5a large current small volume inductance, full closed magnetic low loss low interference!

Single-sided machine paste, whole 4 mm ultra thin, small area heat dissipation, back copper easy installlation and paste heat dissipation film

Based on dc-dc pressure relief, the efficiency is much higher than linear charging circuit, and the heating is much smaller.Charging current 1a, but the input current is only about 0.7a

Optional iron phosphate lithium battery or ordinary lithium ion/lithium polymer battery, can be set in just one jump line

Small size, 1 hair coin size, 1a charging without extra heat dissipation

With overheat protection, overheat automatically reduces current to prevent burning

Temperature characteristics of high precision resistance, full volume 1210 pr
