<p>Hi, i purchased this other board with adjustable voltage, but <strong>non</strong>-adjustable current. Not as awesome as your board! </p><p><a href="http://r.ebay.com/JIwHXt" rel="nofollow">http://r.ebay.com/JIwHXt </a> </p><p>With a heatsink on the chip, the diode burned out while charging a 12Ah li-ion at 4.2V. </p><p>I want to try again with a heatsink on the diode, but my buddy says if the board was current-limited, then the diode would not have fried, so i just risk frying the batteries. </p><p>Your opinion? </p><p>The datasheet for the chip says: </p><p>&quot;An over current protection function is built inside. When short <br>protection function happens, the operation frequency will be reduced from 180KHz to 48KHz.&quot; </p><p>Does that give any reason for optimism? </p><p>Thx! </p>
<p>Your buddy is right. What you are doing is dangerous. You are not supposed to charge lithium cells with constant voltage. Don't do that, you must not use this board again to charge batteries.</p>
<p>Great job.</p><p>Looks like a great module but I wonder if it's as easy as it looks.</p><p>How can you for example control it by an Arduino?</p>
