Best 18650 Batteries for Astrolux MF02? BUYING 16!

BlueSwordM · 2018-12-31T01:23:02.000Z

Yeah, it’s harder if you need protected button tops. If you only needed flat tops, I would recommend these instead:

Set of two (2) LG MJ1 3500 mAh 18650 battery cells – VRUZEND DIY Battery Kit

Only 19$ extra.

Doesn’t the MF02 support flat tops though?

Since the light includes low voltage protection, you can just assign 4x18650s to each light, and never swap them to other lights. THAT IS PARAMOUNT IF YOU DO NOT USE PROTECTED CELLS.

TLDR: But MJ1s from the link above, and assign 4x18650s to each light. Label them as SET 1.1, SET 1.2, SET 2.1, SET 2.2.

This is how my friend in police did this with his BLF GT, and they have been satisfied with it for many months.

For a charger, just get the Miboxer C8 from here:

Good idea on the labeling with a sharpie!

Also, the MF02 battery carrier has plastic rings around the + contact points. I guess they are designed to keep the button top in place without sliding around, but I am a newbie to battery carriers and batteries so I couldn’t confidently state their purpose. Maybe the rings are there to prevent an incorrect -/+ orientation, so it wont make contact and prevent damage from occuring. Here is a picture from an excellent guide by maukka:

Also, he wrote this:
“Batteries are inserted in a separate carrier (2S2P). The center contact is positive and connects to the spring on the driver. The outer edge connects to the brass retaining ring. You can remove the plastic spacers if you want to use flat tops, but as there is reportedly no polarity protection in the driver care should be taken with the orientation. Short flat tops such as Samsung 30Qs may also be quite loose in the carrier.”

The LG HB2 fits nicely so I would imagine most flat tops will be snug. I’ve ran almost everything in mine without issues. Anything much longer is tight.

You are exactly right on your second assumption, the plastic rings around the + terminal are designed to help stop accidentally reversing polarity. Once removed you can run flat top batteries, with them installed you can only run button top. They easily remove without any damage and are just taped/glued in place.

Xenovora · 2018-12-31T02:22:08.000Z

Thanks Fate, I would rather spend the extra 35$ on button top protected cells and keep the rings so that the other 4 individuals who will be swapping batteries with no li-ion experience won’t damage the lights. Costs 5x more to replace the two lights than just buying batteries designed to fit with protection.

texas_shooter · 2018-12-31T02:45:23.000Z

Turbo draws slightly over 3 amps and high only 1 amp on each cell in it’s 2S2P configuration. My battery choices would be;
Sanyo/Panasonic NCR18650GA 3500mAh - Button Top
Samsung INR18650-35E 3500mAh - Button Top

These are quality cells and protected or not is your call. Any other cells with 15-40 amp draw capacity is only going to lower your run time, as they have lower capacities.

These are actually in a recess around the post. There is a groove they sit in. Not glued. One of the few I’ve ever seen this way.

Turbo draws slightly over 3 amps and high only 1 amp on each cell in it’s 2S2P configuration. My battery choices would be;
Sanyo/Panasonic NCR18650GA 3500mAh - Button Top

Thank you! Why if I may ask, do you suggest these cells over the LG MJ1s 3500 10A protected button top cells that Hondarider recommended above?

Are you sure the protected versions of those two you recommended fit?

BlueSwordM · 2018-12-31T03:21:36.000Z

Eh there’s only an minuscule difference between all these 3500mAh cells.

So get the cheapest protected one there is, being the MJ1 that I linked before.

Noted… about to buy 16 LG MJ1s… protected… from ilumn as BlueSwordM linked above… any final objections or other concerns/recommendations? I will spend $100 in 1 hour.
Thanks

I’ve never used them. The two I listed I’ve been using since they came out and trust them. The three should all be fine. I was just pointing out lower capacity/higher amp cell would offer no boost in brightness but would lower run time.

I used the Sanyo/Panasonic NCR18650GA 3500mAh in it. I’ve since sold the light to an officer, but did replace the cells with protected ones as he was new to lithium-ion lights.

Newlumen · 2018-12-31T03:46:01.000Z

If you are from US, just buy it from illumn… why wait 20-30 days from the oversea?

Illumn offer free priority s/h over $50 and more…

I recommend just buy Samsung 30q button top.

I think these will be 30-50$ more for 16, than the LG MJ1s protected button top 3500mahs. Do you know of any other price/discount/shop? I’ve been looking. 16 will cost me 135 at my best finding.

Thanks but the 30qs are unprotected and low capacity. I’ll be using Turbo for 50 mins/week for 2 years straight, and need the highest capacity and longevity out of these.

if the batteries are only used in the light and a dedicated charger nothing speaks for 3500mAh mixed chemistry cells without PCB

Cereal_killer · 2018-12-31T12:38:10.000Z

Have you considered how the cells will hold up to 2 years of charge / discharge cycling? 30Q’s will likely be better performers for half that stated lifetime than any 3500mAh cells will. The 3400/3500mAh cells degrade from cycle count faster than good old 30Q’s…

What you should do is get contracted now to provide replacement cells in a years time.

Also, whenever I would provide li battery powered lights to a police dept / agency I would always include a laminated “cheat sheet” on safely handling li batteries to be kept with the charger and I would also try to give a few different guys (on different shifts) a short in-person safety brief so atleast someone had some first hand instruction.

Do they know the basics like don’t leave cells sitting in the charger after the charge is complete and not to force the light to run after its tried to shut itself down cause of LVP kicking in (many many people not well-informed do this, not just cops, hell I’m constantly yelling at guys on my job sites to take 90 sec to swap batteries instead of trying to continously bump the output back up after a LVP step-down, and they know better).

Contracted to get replacement cells? Like a pre-order type thing? Does this save a lot of money for some reason? How does that work as opposed to simply buying 16 more when needed?

Yes, there will certainly be hands-on training with 2-4 individuals who will be charging the batteries and a cheat sheet guide.

Also, these batteries will be charged in this way:
The charger will be connected to a master power switch which is used for 2 hours M/T/W/T. During those 2 hour periods on those 4 days, the back up 8 cells will be remain in their charger, but the power will be turned cut by the main switch after the 2 hours. The cells won’t ever be getting a full 6+ hour charge, but 2 hours at a time. If it doesn’t reach max, it’ll do it the next day. The charger has over-charge protection.

During each of those days, the other 8 cells will be used in the lights, 10-15 mins/day on Turbo. Every Thursday, the 4th day, myself or another individual will swap the batteries from the lights, with the 8 fully charged cells (over 4 days) and put the drained cells into the charger to be charged the following Monday 2hrs each day as the main power is turned on.

Thanks Lexel. I do prefer 3500mah over 30Qs even if they don’t hold out as long and need replacing sooner, because I fear 3000mah won’t suffice for 50 mins of turbo over 4 days without a charge. I suppose I will go the unprotected button top route, since it will save money and fit better, and will only be used for the lights and dedicated charger.
