I agree that it's a bit of a pain, but in the grand scheme of things, it's just a couple small (albeit hefty) plastic boxes in the carryon. Well worth the faster recycle time and all-day endurance. The Li-ion cells in the new Maxi are a much better solution, no argument about that, but I'm not dropping the price of a liveaboard trip just on that convenience.

Yes, I'm a bit stigmatized in that regard. Egyptian customs once confiscated all my Eneloops – they probably just needed rechargeable batteries at home.

I just find it sad that they're currently selling the "old" flashes in promotional campaigns, but can't offer a discount to a customer who isn't really happy with the product to restore their satisfaction.

 

I probably should have just waited for the Maxi 🙂

But as the saying goes, other parents also have beautiful daughters.

Egypt is a very special case. September 2020, Taba crossing, they demanded I leave my entire rig at the customs shack, to be picked up within 30 days. Two years earlier, there was no issue, but now they wouldn't budge for love or money. I had three liveaboard booked back to back and had to turn around and go back to Israel. I will dive out of KSA before I set my foot in Egypt again.

Fair enough. 👍

One month ago in Zurich airport security control... wouah 2 x 16 AA baterrie box... ( and a box with 6 x 32650 )
It was the first time i've been controlled... and that the agent wanted to make problems...  To many batterie... but it wasn't Li-ion bat... and I said it for 2 person...

I was lucky the second agent said it's OK...

(..)

I've puzzled though, Landvogt, why you don't  want to go with the Boosters and just use 8 batteries at a time. 

(...)

 

 

Pay an arm and a leg for strobes, be forced to spend another half a grand on pretty much "mandatory but not included" battery extension that also increases strobe size/weight, and get to carry half a kilo of batteries alone plus an armful of chargers.

Could not resist. You may spank me now😉 At least left that "Apple 8GB of RAM" thread alone....for now 🤣

Earlier this year, an Airbus A321 aircraft burned on the ground in Korea due to a lithium battery power bank problem. 

 

 Thankfully, there were no casualties before takeoff.

 

 Since then, the rules have been changed to carry on only 5 lithium batteries on board at the airport in Korea.

 

 Not long ago, I boarded an aircraft and my strobe battery was ni-mh battery, not lithium, so I was able to get through the checkpoint safely. Of course I was on the plane with a lithium battery, such as focus light, light batteries for nightdiving, etc.

 

Recently, Hong Kong Airlines also caught fire due to a lithium battery problem.

 

 Perhaps it will be more difficult to fly with lithium batteries in the early future.

 

 FYI I'm not a Retra user. I'm an inon user, but I'm seriously considering upgrading to a retra pro max that uses a ni-mh battery.

 

 I will use a ni-mh battery powered strobe in the near future for lithium aviation regulations.

When traveling, I use a compartmentalized backpack with two strobes, each with batteries installed. Spare batteries stay in the chargers. I’ve never had any issues at security, aside from the occasional curious check, likely due to how the large capacitors inside the strobes appear on scanners. NiMH AA batteries are generally considered safer than lithium cells by airport authorities, as they contain significantly less energy per cell.

 

Regarding the performance concerns with 4xAA batteries: the Retra Flash is designed to protect batteries from overstrain, helping to extend their lifespan. If battery voltage drops too much or too quickly under load, the strobe will stop discharging to prevent damage. Even if the strobe allowed them to operate, you’d face significantly longer recycle times and significantly fewer flashes per charge, leading to a frustrating experience. That’s why it’s recommended to invest in a dedicated set of batteries specifically for use with your Retra Flash. Depending on your location, a set of 4xAA Eneloop PRO batteries usually costs around $20. A small investment for consistent and reliable performance.

Yes I bought the last Eneloops pro for more or less 5 € / pc.

In comparaison of the cost of a dive trip...   hummm it's nothing 

The old one (not dead) will be used at home at different place.. where they will last enough. It's the second life for it.

Not a bad idea

I thought regulations were to have batteries outside the devices when possible? I always have my batteries in dedicated plastic boxes and the strobes, torches, etc, empty. 

[Oskar - Retra UWT]

I haven't heard that one before, but perhaps. In any case, AA NiMH batteries remain the more reliable power source when traveling. They're also much easier to replace if something goes wrong during your trip. That's why we plan to continue producing our AA-powered line of strobes, professional users rely on this level of robustness and versatility.
