<div class="detailmodule_html"><div class="detail-desc-decorate-richtext"><p>Features: <br/>1. Designed specifically for single string 3.6V lithium iron phosphate batteries, with precise charging cut-off voltage. <br/>2. Supports a maximum charging current of 2.4A, with a charging efficiency of up to 92%. <br/>3. The blue breathing light indicates the charging status, flashes slowly while charging, and stays on when fully charged. <br/>4. Wide input voltage range, compatible with 4.5-5.5V Type-C interface input. <br/>5. The ultra-thin design is only 3.2mm thick, with a compact size that is easy to integrate and use.</p><p>Parameter: <br/>Product Name: Single string 3.6V lithium iron phosphate charging module (can only charge, not discharge) <br/>Battery: Suitable for lithium iron phosphate batteries with a reference voltage of 3.2V, with a charging cut-off voltage of 3.6V (batteries can only be connected in parallel, not in series). Cannot be charged with ternary lithium batteries or other batteries! <br/>Input voltage: 4.5-5.5V <br/>Charging current: maximum 2.4A <br/>Charging efficiency: typical value of 92% <br/>Indicator light: Blue breathing light (the blue light flashes slowly during charging and stays on when fully charged) <br/>Product size: 16 × 23 × 3.2MM (excluding the protruding 1MM of TYPE-C) <br/>Usage reminder: <br/>The charging cut-off voltage of 3.6V is set by the chip and cannot be artificially changed, so there is no problem of inaccurate charging. The correct method is to fully charge the battery, plug and unplug the charging cable, measure the battery directly with a multimeter, and watch the voltage while charging. When it reaches 3.6V, it will stop charging. (Note: Some batteries with high internal resistance will quickly drop after being fully charged. We have tested ourselves and found that many batteries have this problem. After being fully charged, the voltage will drop by 0.01-0.02V within a minute.) <br/>be careful: <br/>After receiving it, do not connect the battery. First, plug in the charging wire and the indicator light will turn on (contact customer service if it does not light up). Connecting the positive and negative terminals of the battery in reverse will cause it to burn out!</p><p>Package Include: <br/>1X module<br/><br/></p></div></div><br/>
