2in1 charge discharge board module for 1850 lithium battery DIY Power Phone Bank  5V 1A 2A Dual USB LCD all-in-one Boost Lithium ion Battery Charger Module Board  5V 2A Dual USB LCD all-in-one Boost Lithium ion Battery Charger Module  USB Lithium Li-ion 18650 Battery Charger Module Board DC 3.7v 4.2V to 5V 1A  Lithium ion battery 5V 2.1A USB all-in-one boost charge iPhone capacity LCD



Version 1:


The TP4056 Version use two charging Chip, has 4.2v and 4.35v model, linear buck charger.
(the 4.2v and 4.35v is charging cutoff voltage, you can choose the model according to your battery)

Notes: 


In order to facilitate the use of 4.35V as a battery of XD, design new version for 4.35V. Non TP chips, but the same performance, the same voltage  9V, the current is about 1.8A. In order to guarantee the safety, 4.35 version of the cut-off voltage range for 4.34V±0.04V, center 4.34V more security ~ 4.35v battery can be full charged easily.
The input voltage: 5V
Maximum charging current: 2A or 1.8A
Charge cut-off voltage: 4.2 V + / - 1% or 4.35v
PCB Size: 13.1*20.2*3.5MM


Version LI4001:


Switching buck Charger, higher efficiency.
Parameters are as follows:
Size: 15.5*20.5*4.5mm
Input power: 4.5-9V, not more than 9V.
Cut-off voltage: 4.2V ± 1%
Output current: 2A ±  5%
Antihypertensive efficiency: more than 90% (input 5V, output 4V, 1.5A current measured)
Tip: input output positive and negative at the back of the board have don't p solder it wrong, the board comes with red and green LED indicator, welding long foot pin square pad\.
Advantage
A, almost the whole process of constant current. If the charging current is set to 2A, the constant current charging will keep the 2A up to 4.10V.
B, switch buck mode. The efficiency is higher than the linear charging circuit, and the heat is less than the same current linear charging plate, and the measured efficiency is slightly higher than the 5000.
C, using high quality ceramic capacitors, integrated inductor, the performance is more reliable.
D, the back of the board has been marked with the definition of input and output, to facilitate the control.


Version LI4001 Micro USB:


Switching buck Charger, higher efficiency.

Small size of the charging board to facilitate the change micro charging equipment, the current in this size is relatively large ~ so please pay attention to the heat ~
Size: 10.5*23*6.8MM
Charge cutoff voltage: 4.2V ± 1% 
Charging current 1.7-2.2A
Input voltage: 4.5V-6.5V (based on input capacitance measurement)
Charging instructions: red patch LED is located on the opposite side of USB micro, no battery flashes, charging long bright, full of quenching.
Wiring Description: Input power for the standard USB micro interface, please confirm the power supply has 2A output capability.
