Sky Eagle have released a new PB3000 Lithium Power Pack for speedlites, currently listed on Amazon from around $80. If the PB3000 can live up to the specs, this unit is looking to be a lot of bang for your buck, particularly at the current low price.
Single flash Lithium power packs like the PB3000 are just slowly starting to emerge now, and as an alternative to the crazy battery management required if using a number of AA cell packs, they just can’t come soon enough.
If you need to speed up recycle time, or avoid constantly changing batteries mid shoot, inexpensive 8 AA packs like the popular Pixel packs around $70 have been the main economical solution for a number of years now. The Godox PB-820 around $120 later emerged as one of the most popular options for people who don’t want to manage a lot of AA batteries individually. The NiMH cells are sealed inside those, and a single wall charger charges the full pack in one go.
Lithium offers the prospect of more capacity, with smaller size and lighter weight. Godox again currently have one of the best Lithium options with the new PB-920 around $200, but those may be overkill for many people in terms of cost and capacity when just using a single speedlight per pack. Also extra weight if you’re attaching one to your belt for on camera use.
So single flash Lithium packs like the new Sky Eagle PB3000 will hopefully offer the best alternative to the 8 AA packs, and if the Sky Eagle’s price is any indication they may well do it just economically.
At 3000mAh the PB3000 capacity is larger than possibly even required for a single flash pack, providing up to 1200 full power pops with a speedlite. The 8 AA packs will get you up to 500 in comparison. So that’s around twice the capacity for a pack of the same weight.
The PB3000, similar to the Godox packs, have a simple On-Off button, 4 LED battery level indicator, charging socket, and a DIN style power cord socket, which are fairly standard now and should be compatible with most Quantum style cords. These cords are available inexpensively for a number of flash brands, so even though the PB3000 may only be listed with Canon or Nikon compatible cords, you should still be able to use the pack with sony etc speedlites with the right cord.
One very handy extra feature which the Godox packs don’t have, is a USB port for charging mobile phones etc directly from the pack as well –
Charging the PB3000 is with the one simple wall charger, and charge time is stated as approximately 2 hours. The charger attaches to a port on the top of the pack, which suggests the actual Lithium battery pack itself is sealed inside the PB3000 case. This is not necessarily a bad thing, but it means you can’t just charge the actual battery separately from the pack, and swap them over as needed. And the complete pack will likely have to be retired once the battery eventually wears out.
There are strap holes built into the sides of the case, but no belt clip directly attached to the back. Which means you would need to use the extra supplied case to attach to your belt.
The PB3000 from LinkDelight comes with battery, power cord, charger, carry case, and 2 straps.

Please note, I have not tried this pack myself, and it would likely take quite some time to be able to gauge the life expectancy and quality of the Lithium batteries inside anyway.

As far as I understand Lithium batteries do degrade slowly over time regardless of how often they are recharged. So if you only intend to use the pack occasionally, the 8 AA cell packs likely do make more sense there. As you can recharge and condition the cells individually, and throw away any bad ones as needed.
