I'm not for sured which 3.6V CR123A batteries on DX would work in the 5W CR123A powered MXDL host? Can I use unprotected cells (http://www.dealextreme.com/details.dx/sku.722) or would I be risking my diode by doing that? There are protected cells (http://www.dealextreme.com/details.dx/sku.3273) but I am worried they will not fit in the host. Any reccomendations are greatly appreciated.

Thanks,
