Title: New Battery Extender Pack
Post by: Goldman on Monday May 20 2019 10:04:19 AEST AM
Hi everyone,

Great news, Howard has created a new battery extender pack for the QED that adds 4 extra batteries to the existing 2 batteries and which weighs only 320 grams (including the supplied cable).

This new extender pack includes 4 rechargeable li-Po batteries, the battery holder, the battery holder cover, Velcro and a lead to connect the battery pack to the QED. The extender pack connects to the QED via the QED battery charging (white) connector using the supplied lead. Refer to the attached photographs to see the individual components and connectivity details.

Combined, this new extender pack and the existing batteries creates 3 sets of 2 batteries. This triples the current battery capacity, providing an increase from approx. 8 hours detecting to approx. 24 hours.

Note that the increased battery capacity has no effect on QED detecting performance and will not harm the QED in any way.

The extender pack has two connectors, one to connect the pack to the QED, the other used for charging the batteries using the charger originally supplied with the QED. When the extender pack is connected to the QED and the battery charger connected, all six batteries will be charged at the same time. Note that the battery charger will operate in the same way, with 2 lights illuminating red whilst charging.

Note that charging 6 batteries will take longer to charge than just charging the existing 2 batteries.

The extender pack has been designed to be physically attached to the left hand side of the detector control box as per the photographs using the supplied Velcro.

It is advised to fit the extender pack to the QED and leave it attached, connected and charged via the charging port on the extender pack. This is for one very important reason:
* It ensures that the 6 batteries always remain at the same state of charge with respect to each other. This is ABSOLUTELY ESSENTIAL.

Words of Caution:
1. NEVER connect an extender pack with an unknown battery state of charge to the QED. In this scenario, separately charge the extender pack and the QED batteries. Once all batteries are fully charged, then connect the extender pack to the QED.
2. Removing batteries from their respective battery holders may over time physically damage the batteries/and or the battery holder terminals. As it is absolutely essential to not damage Li-Po batteries, especially the plastic covering around the terminals at each end, do not remove the batteries once fitted unless absolutely necessary.



Cheers
Goldman

i just dont understand why you wouldnt use quality Panasonic NCR18650`s   with genuine 3400 mAh   $7.50 each   instead of those 2600 mAh battery`s
                                                                                                                                                                       https://www.18650batterystore.com/Protected-p/panasonic-18650-protected.htm

Because they're not protected, protected batteries are better but tend to have a lower mAH capacity due to the little circuit board in the base of the battery.

This website seems to explain it the best

I would prefer protected batteries in any sensitive electronics.
