Hadn’t seen this before, a third party LP-E6NH replacement (for R5, R6, R7, and many others), cheaper, a little lighter, more capacity, and with USB-C port for charging:

How much can we trust Canon to let this work?

Please explain how USB-C at 5 volts can charge a battery to 7.2 volts. Also there must be some charge management circuitry inside, which reduces the space for battery cells, so a higher capacity seems unlikely. Finally, the rating on a battery in mAh is often over optimistic and can’t all be used once the voltage drops.

Not that I disagree with the optimistic values, but USB-C PowerDelivery standard has charging modes higher than 5 volts (up to 48V in the latest version). Otherwise you would not be able to charge the latest R cameras directly via an USB-C cable.

Good points. I see this model is available for pre-order at Adorama and B&H already, so it's somewhat legit.

However, B&H reviews for the earlier Smartrig models are mixed, with some claiming much less capacity than advertised, so you may be right.

Will wait and see actual reviews of this model.

I do like the concept of charging the battery outside the camera directly from USB-C.

The USB-C PD standard supports voltages higher than 5V.
 
I’ve been using the Neewer version of this for the past six months and they have done well. I have five of them. One failed after two weeks but the other four are going strong. I find the direct usb charging to be very convenient.

I have used Neewer third party batteries for R5 and R7 several years now. I have six of them and two Canon brand. The Canon units are ever so slightly (5 minutes) longer lasting in use but both last more the 90 minutes of video shooting for my use.

The Neewer batteries are about 70% cheaper. I love them.

The Smallrig website states 5 volts via USB-C and doesn’t mention the PD option.
 
The USB bus is 5volts. Modern chips can create a voltage multiplier to what-ever voltage you want. These chips are adjusted the requirements of charging while using the 5 volt input from the USB bus

As a battery developer hopefully I can help a little.

The battery will be charged up to a voltage of around 8.2v but perhaps slightly more (8.25v).

The value of 7.2v is made from (2 X 3.6v) which is taken as the centre voltage value and links to the rated capacity of a cell.

This device is likely to use an integrated dcdc in a boost form but how they control the constant voltage phase, constant current phase will be another controller.

The charging current at 2.2A will be a maximum and will reduce as the voltage increases.

The capacity of 2.2* 7.2v = 15.84Wh. To achieve this the 2.2Ah discharge rating will be at a specific current, above that the capacity will reduce.

The battery will need to continue to operate until at it drops to 6.2v to achieve that capacity.

It does but I suspect this isn't a PD device. It's operating at 5v and limited to 2.2A from that bus standard.

Why wouldn't it work? Lots of 3rd party batteries in use.

While there are "a lot" of 3rd party batteries, not all are well-reviewed. The Neewer batteries seem to be doing good, and I always had good luck with the Sterling-Tek LP-E6 batteries for my xxD DSLRs.

Perhaps they take an easy route and simply connect the 5v to a pair of these.

No idea; as I said I've been using Sterling-Teks for many years and never had a problem, so never had any reason to tear one down. Not sure how the Neewers are made either, but they also have seemed to gain traction with a lot of users.

5v at 2.2A. I suspect that 7.2v camera batteries contain two 3.6v cells.

And yes, as with other lithiums like 18650s with USB ports it does take up room. Might be worth it though. Price per watt might still be lower than Canon.
 
Dual or triple chargers for E6X platform batteries.

I see quite a few choices of third party batteries sold with a dual or triple charger. I have a HLX-E6N which can charge two batteries and can connect to a power bank.

They seem to claim that they operate from a 5v 2.1A system which is then shared amongst the batteries.

Personally I've noticed that when a canon brand battery is charged the charge lights go out all together but the Hahnel it turns green. So some difference in the port behaviour.

Hähnel -

I post this as a common alternative to having a usb C charged battery.
