Hi

i'm about to use this driver:
http://www.kaidomain.com/ProductDetails.aspx?ProductId=5313

in an old WF-400 host together with a R2 and a 18650 cell. I'm having a hard time getting this properly attached to some heatsink. So i'm wondering if the driver needs heatsinking at all at so low voltages as 3,7V. If not i would just epoxy it into place but there would just be epoxy at the sides and it would not have contact to aluminium or other metal at top or bottom.

Thank you all in advance for your comments

greetings

I use permatex ultra copper high temp gasket maker. I just glue the driver in place with this and it makes a great shock absorber and helps get rid of the heat too. Fill in everywhere with it!
