4 in 1 Single-Cell Li-Ion Battery Protection Mobile Charging Boost Output 5V Board/0.5A Mobile Power Board

DESCRIPTION:

• Size: 38 * 10 * 4mm 
• Charging voltage: 5V
•  Charging current : 400-500MA become hot during charging is normal. 
•  Boost Output: 5V 
•  Output current: 300 ~ 400MA; suitable for use in less demanding situations.

PERFORMANCE:

 This board integrates a single lithium protection board, charging panels, and booster plate three functions into one. 

 Protection: over-discharge, over charge, over-current protection. 
 Charging function: You can be a boost to the single-cell lithium battery charge, of course, also supports multi-section parallel charging lithium. 
 Boost function: for single or multi-cell lithium lithium batteries in parallel (parallel unlimited number) to achieve step-5V output. 

Usage: first batteries to boost the positive and negative plates welded (B + / B-), then the charging port P + / P-plus 4.8-5V voltage-activated protective plate section, and then detect boost output port V + / V - (measured with a multimeter has a 5V voltage output)
