Default Re: 3.5W NDB7A75 445nm Laser Diode

The Efest work pretty good. I had a lot of voltage drop and battery problems with a build with that diode.
The Imren tested best and worked best, followed by an LG battery I had gotten from Larry, the Efest came in third best followed by a bunch of Panasonic and sanyo batteries.
If the Efest doesn't work out for you try these ,2 PC Imren IMR 18650 Li ion Battery High Drain Rechargeable 3 7V 2600mAh 38A Red | eBay the seller ships really fast. I bought up about 20 of them Imren is suppose to be coming out with a 40a battery but I haven't found it available yet. Good luck with your build

There's another forum that had a thread about battery comparison (CPF I think) interesting info. Larry got back to me.
Pretty soon I'll be like the rest of you and have more batteries than I know what to do with! I keep ordering them.

Thanks for the link

It's nice to have an assortment of batteries. I use the high capacity ones that aren't capable of delivering high current in my low watt builds, and the high current ones in my high watt builds.

I used to swear Panasonic was the best battery out there until I built the 5.6w 445 using one 18650. Then I had to find something that would work. The build pulls like 5.5a - 6a at the tail cap. I thought a 10a rated battery would work fine but it wouldn't. It would work, just the battery voltage would drop under load,

I even took the wrapper off an Imren , Larry and I were wondering if it was a rebranded cell. It appears Imren actually makes the cell. It's an amazing battery.

I had bought one of those chargers they had in the GB thread. Measures internal resistance, measures the capacity of a battery. Really a handy charger to have.

I had to go to harbor freight yesterday and get one of those plastic parts bins to store batteries under my bench. My bench was getting cluttered

What kind of driver would be able to deliver the required 4+amps for powering this diode at 5W ?
Need to use 2 x-drive ?

I will use wall adapters and not batteries though .

Most do 5W with the 3.5A X-drive plus or minus a few hundred mW. Best option in my opinion.

Yep my original testing shows you start loosing power @ 4.5A+. If you figure a good overdrive current is about 10-20% back of foldback that would be around 3.6A-4A as a max. The 3.5A X-drives are a buck driver which is readily available. There are some available boost drivers that go up to 4-4.5A but those have pretty hefty requirements like a near 10A current draw off a single Li-ion but these 3.5A X-drives draws 2-3A which most switches and batteries can handle pretty easy which is why I like the buck drivers.

I'm with you on that. Buck is the way to go 100%, and Lazeerer's drivers are awesome.

BTW - impressive pricing on your NDB7A75s right now!

Is that just a repurposed LED driver, or is that a driver you designed?

I asked the maker to set the amps to 4A to 4.2 max for me. they were used for LED but I have used this kind on my 3w laser set at 2.5A they run cool work good on 2 -18650 batteries.
On the 4A driver I have got a lot of diodes going to 5.7W ONE HIT 6W most around 5.5w

No. Ha ha ha. I guess I gotta watch for dangling modifiers.

Anyway can the diode be run off two 18640s?. I am cosidering reusing the host i have in this thread
need new diode and module

Or would the driver be too long.

Default Re: 3.5W NDB7A75 445nm Laser Diode

So realistically what's the lifespan of this diode running it off a 3.5A driver that's well heatsinked? how many hours of MTTF?
