7135一定要散热的，不然一会儿就过热保护了，也就是电流达不到标准电流的原因

<p>谢谢楼主，我想把这款手电改造成3W的，并用3个 <font face="Times">1000mAh&nbsp; 7号</font>镍<font face="Times">氢充电电池供电，</font>不知道可行不？最低要花多少成本？</p><p>您能抽空看看我发的这编帖子吗？帮忙给点意见！！！</p><p><a href="http://www.shoudian.org/dispbbs.asp?boardID=10&amp;ID=21562&amp;page=1">http://www.shoudian.org/dispbbs.asp?boardID=10&amp;ID=21562&amp;page=1</a></p>

我当时买这个手电，加邮费（邮政平邮）花了34元，晕.........[em06][em06][em06][em06]

<p>那没什么，人总是买不到最便宜的东西的！哈哈</p><p>我买也是团构价。个人一次买了20把！</p>[em04]

jack1505

<p>支持一下楼主，我也有改造这种手电的想法！很想和你交流一下</p><p>为什么不买一个恒流动成品板呢？那样多方便，而且楼主好像没加二极管，这样就没有电池反接保护了</p>
