Portable battery for flash

1. After using a Turbo for over a decade before spending about $25 on a new lead acid battery, they are extremely economic to use...in my case, even amortizing the original new purchase price, it was less than $3/mo
2. They work with many, many flash units, not merely the Canon flash
3. Lots and lots of flashes without changing AA batteries in the middle of a job

amortizing eneloops and a 3rd party young nuo pack is cheaper and more cost effective than the quantum sla route. <. $3/mo

8 AA eneloops go for $21 at costco

plus, AA batteries can be used in other electronics rather than just ONE specialized flash.

any way you look at it, quantum battery packs are overpriced, old tech, and too specialized for practical use in 2012. They had their place in the 90's, but not anymore. Quantum battery packs can be bought used for around $80 with typically used sla batteries. Add to the fact that you have to buy special batteries will only add to the price.

-the vagabond mini + any 120v strobe is a better value for higher power setups
-young nuo battery packs + eneloops cover the speedlites
-yn 565ex fill the low- middle range

quantums are good for portraits, but the cost factor does not fall in favor of their system.

Pulling out the cost of the Turbo unit itself to compare battery price, 10 years on a single $25 lead acid cell...$0.208/month. Compared to $21 every three years (average useful life of NiMH) $0.583

As for price of unit itself, I have used my Turbo with four different brands of flash units spanning two decades...the 8 AA cell pack is usable only with Canon flash.

For greater initial investment, one gets greater flexibility and longer ultimate longevity of use. Not everyone needs those benefits, but some of us do.

I'd rather have the flexibility of being able to pull batteries from a speedlite to an emergency flashlight or toy than being locked into an expensive turbo battery pack system. You can't ignore the initial investment cost of the quantum battery kit and focus just on the cost of a replacement battery... That would be like purchasing a car solely because it has power windows vs manual crank.

there are just better alternatives on the market that can be had without breaking the bank.

otherwise, there would be more quantum battery kits being traded or sold based o. Supply/demand factors of the product.

for what it's worth, eneloops have a much more durable battery life than that of the inferior nimh 2600mah type batteries since the cheaper nimh's are much more prone to suffering from battery memory.

I have the turbo blade under camera mount. Only use it when I need 2-3FPS in indoor or nightime settings, which is not often. I regret buying. 1 year old and used 4 times over 2 days for less than 300 shots, so far thats about $1.50-2.00 a shot when you figure the cable price too. It is the weight it adds to the camera which already has some good weight with the BG and a heavier wide lens. Wish I would have gotten the remote one I can wear on a belt. But .... it does charge fast, I would need 2x8cell chargers to get close to as many shots from nimh AA's.

I use chinese Godox PB820 Power Pack and sometimes my DIY batteries without any problem.

I started a blog about lighting techniques in Spanish some months ago and recently I started the English translation.

My experience with Godox (will be in English soon !)
