What is a Mag85?

Question from a Mag85 noob:

One thing I am not understanding is how folks are charging their 9 NiMH cells. Is everyone using pack-type smart chargers (which I understand are superior). I have a bay-type (4) charger and I don't know the best way to get 9 NiMH cells charged evenly. Do I purchase 10 cells and overcharge the stuffing out of the non-used cell in the dumb charger, or can a 4 or 8 bay smart charger charge 10 cells in a convenient manner? Sorry if this seems like a dumb question but I've read this thread twice and I can't see the best way of going about doing this without purchasing a pack-type charger.

Also, can anyone make a guess on the lumens from 9xAA Alkalines? I know the runtime will stink but my bulb lumens will go from ~1200 (NiMH) to ??? I can get them free until I can figure out a good NiMH solution without spending a lot of $.

Sorry for the newbie questions, I don't even have my Mag85 yet but I am trying to plan in case I come across some used battery / charger configurations in the Marketplace that would prove satisfactory.

Thanks,
K

I've been visiting often, checking for answers to this question.

I'm hoping someone in the know will answer someday ;)

I'm not only unsure about the charging situation, I'm planning on using fivemega's 9>3d adapters( I would like the charger to plug directly into the 9-cell adapter), but also what battery would be most prudent with a Mag85. I know technology has changed since a lot of these threads were written.

I have most of the components for a Mag85, I just need to decide on what's gonna power this thing.

Boy is this an old thread.
I just got through putting together my mag85 and I couldn't be more pleased. I went with the FM 2.5 Throw Master head and it does throw. I'm also using the FM 9xAA battery holder that came with a male plug for charging. I just soldered it to my charger leads and plug it in my battery holder. I loaded it with Titanium 2700 batterys. Some like eneloop LSDs and some like Titanium 1800 high currents. I believe any quality AA ni-mh you want to use will be ok. If you want a long run time you may want to use 2500-2700 mha.

The most highly recommended batteries are Eneloops, followed by Sanyo 2700's. The Eneloops will provide a higher voltage (less voltage drop) while the light is on and will hold there charge better when the light is off (rated at 80% charge 12 months after charging). The Sanyo 2700's will have longer runtime (maybe 20% longer) as they are a higher capacity battery.

As for chargers, get a pack charger, way easier than removing the batteries from the holder all the time. You can use either a dedicated 9.6v charger if you only have the mag85 to charge, or get a hobby charger that will also charge Li-Ion batteries as well as NiMH packs of differing voltage.

Cheers,
Nova

So far I'm getting good service out of the Titanium 2700s. Most don't give them as high a rating as the Sanyo 2700s but the Sanyos are 30% more expensive. I'm showing arround 2.3ah with the Titaniums at 3.2a. I don't believe the Sanyos are delivering 30% more than the Titaniums.

Is there anyone else who sells a complete modded 3d mag other that juancho/blackbearflashlights? I heard his prices are competitive, but $200-$300 is a little more than I'm looking to spend on a platform that started at $30. Please advise, thanks and sorry if this has been previously addressed; I didn't see where.

I am too lazy to post the links but the easiest way to make a Mag 3D into a Mag85 is to get the following

-Fivemega Bi-Pin Socket (Can use Kiu Socket also)
-Fivemega 3AA 3D Battery Adapter
-Borofloat lens from flashlightlens.com
-Fivemega Bi-Focal Reflector (Can use another metallic reflector)
-WA1185 Bulbs

I don't believe you could build a m*g85 for $30! The last ones I built were arround $104.00 not counting the cost of the host.
9AA FM holder-------$39.00
Kiu kit---------------$12.00
WA 1185------------$6.00
Bi-Focal reflector----$20.00
Boro float lens-------$ 6.00
9ea. AA eneloops----$21.00
Total----------------$104.00
You will need a charger too.

You can reduce the price a bit by using 3xIMR26500 in a 2D Mag, filling the space with the ubiquitous PVC sleeve and doing a tail spring shortening mod. That costs about $50, vs. $60 for the 9AA holder and Eneloops. You might have to spend another $1 or so for a voltage drop resistor, especially when using the Kiu socket.

For the price-sensitive, you also can use a KD MOP reflector for about $15. However, I think that the extra money for the FM bifocal reflector is well-worth it.
