Hi everyone, I am completely stuck between two choices and I would like your advice/ what you think is better. I am building a 445nm laser with a nice host which has a great heatsink for the FMT driver. The X drive runs at 1.8A and costs 15$ and the FMT driver runs at 1.7A and costs 27$, giving...

Ok, I see. Is it possible to get a gray coloured version of the S4 host though? Those host bundles are a tad to expensive for me :/

That steel- coloured S4 with the blue focus adapter is exactly what I am looking for. Is there a link to that exact model?

And how can I be sure they will handle 2A?

Wouldn't this be a better choice? 2Pcs UltraFire 18350 1200mAh 3.7V Rechargeable Battery | eBay Of course they are not 1200mAh but I think they will still be more than the 700maH 16340's you linked me, sinner.

I am thinking of buying this laser module from DTR: 2W Copper 445nm M140 Blue Laser Module W/X-Drive & 405-G-2 Glass Lens | eBay In the description it mentions "Input voltage range is 6V-8.4V. Great for use with two Li-Ion's or Lipo's. Suggest two 16340/18350/18650 3.7V Li-Ion's" So.. I...

Hi everyone, I am planning to buy this battery for a laser: Panasonic NCR18650A NCR18650 18650 3100 3.6v Rechargeable Battery Made in Japan | eBay I will however be using it with a (cheap) Chinese charger that came with a green laser from DX. Using a cheap charger to charge the Panasonic...

Haha great! Except I prefer the DX host over the Ebay one, I will choose depending on the price of the heatsink + shipping. When you get the Ebay host, can you tell me if it has a heatsink installed?

Okay, thanks for the heads up! Hope to hear from you when you get it :)
