Hi all,

I posted re: the QED Battery Extender Pack back in June.

Refer to http://australianelectronicgoldprospectingforum.com/qed-users/new-battery-extender-pack/ for information.

Nothing has changed since then, other than a few people are using them.

Cheers Goldman

Hi all,

Now that I have changed the photo file extension here are some photos of a QED fitted with a battery extender

Cheers Goldman

These were the batteries in pic (no idea of brand) that came first with my QED and now looking to update to a higher mAh set such as the Panasonic NCR18650B 3400mAh Protected Li-Ion Battery (Button Top) so is anyone using them instead of the Nexcell 2600mAh that are now included with the QED?

Hi Goldman,

I have been using the Boruit  6000 mAh batteries since 2017 in my setup as shown in attached pictures.

Regards, Ian. ::62::

Yes im using the NCR18650B 3400mAh protected Panasonics.

I swap between these and the Nexcells.

Found this in regards to Li-ion cells.

"It turns out that buying the cheapest battery with the highest capacity isn't worth it. The declared capacity of the battery often does not correspond to reality. The actual capacity can be up to 25x less! Sometimes it is even technically impossible to fit the declared capacity into the size of a 18650 Li-Ion battery. We often see Li-Ion cells with the capacity like 5800 mAh, 9900 mAh or even 12000 mAh. In fact, 18650 size Li-Ion batteries can't have higher capacity than 3500 mAh. It's just not technically possible. Usually the real 18650 cells tend to have a capacity of about 1800 - 2500 mAh. There are also 3400 mAh cells, but the higher capacity is at the expense of lower allowed discharge currents. Therefore, even in the modern cordless drills and other tools we still see cells with only 2000 mAh capacity. If you see a 18650 Li-Ion cell over 3500 mAh, the capacity is fake. The maximum capacity may improve with progress, but very slowly."

Interesting Mylab, we see this with LED’s regarding Lumens.

I wouldnt be totally convinced this is the case with the Panasonic NCR18650B’s though. They dont look to be your generic retail cell.

All true. Any amount of false claims out there.
 
State of the art atm are these genuine Panasonic NCR18650GA from a respected seller recommended by Mick the Mechanic. Check out all the supplied load performance graphs:

They look to be an excellent option for extended range out in the field.

A quick question: Are the proper batteries for the QED flat top or button top?

Welcome aboard!

I use either. The important thing with flat tops is to ensure they are making proper terminal contact.

I  purchased these from the link JRB posted, also quick delivery as well.

Yet to try them out although these will definitely extend run time over the 2000mAh I used previously.

How does the battery extender attach to the QED? Can it be removed or is it permanent when attached? I think it's a great idea and there are times that I would love to have one as I've had my batteries go flat on me before at the worst possible time and went unprepared and a long hike back to the car so it ended my day's detecting but other times I'd find it not necessary so I'd like to be able to remove it if possible.  
 
-- edit: I just read the post about it being removed by Velcro which is cool, in regards to charging if the batteries are in a different state of charge does it damage the QED or just the performance of it?  Just wan't to know why it's essential the batteries are the same level of charge and not just recommended.

I should order myself one.

I like the minimal weight of the PL2 so i try and keep extras as much as possible from being mounted to it. I carry a couple of spare batteries in my pocket. Because the skin of these batteries can be damaged, i carry a guitar pick in the battery compartment to assist changing batteries.

With 4 batteries in the extender pack and attached to the control box, as in Goldman photo, it would help to counter balance when a larger heavier coil is attached to the QED.

If I were to use the wider width extender pack I would attach it to the right side of the control box. Therefore that way when swinging the detector the extender pack will not hit up against the right side of my body, well that is the way I would attach the pack.

And at present I have the small lightweight narrow width Amp attached to the left side of the control box which I can now use to adjust volume for the Nokia external speaker and with the Amp in that position easy access to plug in my headphone.

However many seem to be using the extra expense wireless setups with their QED's and I being old fashion by being attached to the detector as I am use to when using my GPX.

Btw I have damaged the skin as Blip said can happen, the blue batteries in my photo above (positive end of 2nd battery from top)

Some extender packs that Howard made can be fitted it the RH side of the box (using Velcro), it’s the positioning of the connectors that determine LH/RH attachment.
 You MUST never connect any lithium battery pack to the QED without knowing the state of charge (SOC) of both the QED and the extender pack. If for example, the QED Batteries are fully charged and the battery pack is flat, then you will get a very high current flow between the batteries in the QED and the battery pack, which will cause damage or blow the batteries up.

Therefore it is absolutely essential to fully charge the QED, then separately fully charge the extender pack, then and only then connect the extender pack to the QED.

From that point on, leave the extender pack connected and charge all 6 batteries together using the spare charging connector on the extender pack.

Of course it’s ok to remove the extender pack at any time, but before reconnecting you MUST do as above before reconnecting.

Safety first always when using lithium.

Cheers Goldman

Garry, im finding the balance fine with the 20” NF Adv. Lack of weight is priority. I know mate, personal preference.

Brian, does Howard supply a little note with the extender pack depicting the dangers of these Lithiums? Liability concerns!

Al being tall and skinny and accustom to using a bungee cord, as well with the QED, so do you use a bungee cord at all?

Howard and I do provide a QED Battery Extender pack explanatory page with each pack. The basis of which is the tip I wrote some time ago in relation to the B.E. Pack.
