A fabulous box! Sealed, dimensions worked perfect for me.

Reviewed in the United States 🇺🇸 on January 20, 2019

Color: BlackVerified Purchase

I have several rechargeable NiMHh batteries, and now I seem to be collecting Li-ion, LiPo, other various types to add to the collection. The Lithium batteries are deemed more dangerous than other types, although that can be disputed. You may find the vast majority of storage boxes for lithium baatteries, i.e. 18650, 14500, 10440, 16430, etc. are all small sqare ones that hold 4 batteries. This is because you aare not supposed to keep all your lithium based batteries together in case one does catch firee. The problem is I ended up with all these 4-slot battery boxes cluttering up the place.

Now let's face the facts, I'm not going to spreead battery boxes throughout the house to keep them seperated, I'm going to keep all my spares in one place. I thought of a military ammo can, which is sealed, then there would be no fire. As long as the batteries are in plastic cases first that would be OK, but metal boxes have the potential to short-circuit a battery if it ids not encased. There are no organizers for these small boxes for safety reasons.

It may not be perfect, but I found this Seahorse 300 Protective Case made of plastic, sealed, and battery boxes fit perfect. The square ones, or I bouthe the Whizzoptech 10 battery trays (which run VERY tight on lithium batteries), or the DOUFIRE Battery Storage Containers with AA/AAA converter cases (I tried the converter cases, NONE of my 10440's fit), and I bought some 8 x 18650 boxes which are plentiful here on Amazon. From the pics you will see this is a very nice fit! Yhe only thing left is I ordered some 1" foam I am going to glue in toe lid to fill the space and keep the boxes snug. If I didn't I could fit more in butr I don't need to.

The case is fabulous, heavy duty, I think I could run over the thing with my truck and it would be just fine. I mean it is SOLID! If you are hesitant to pay $21 for a plastic box don't be. It's worth every penny. It came with a catalogue of their product, they have some very nice boxes!

Not a Pelican But well worth the money!

Reviewed in the United States 🇺🇸 on April 21, 2019

Color: BlackVerified Purchase

I've ordered two of the Seahorse SE-300 Cases and have had one of them in use for two years now for use in my truck for carrying a mirrorless DSLR and later a Sony RX10 Mk III camera kit (did the internal foam layout / install myself), and the case has held up extremely well both in the North Carolina Summer heat and Winter along with some jostling around with no warping or damage to my cameras or equipment so it had done everything I have asked of it well enough that I purchased another one. The only thing I haven't tested is just how waterproof they are, but in checking the seal contact area even after the temperature extremes the seal has a good indentation with no gaps anywhere to where I wouldn't have an issue taking my two year old case canoeing etc for fear of my equipment getting wet. Now if I were white water rafting?... Well I'd probably buy a Pelican just because, but for most regular demands this is a quality case that won't break the bank.

For the money, this is a GREAT case. I bought it to use as a small emergency kit to take with me when I am kayaking down the river. I have fire starting gear, first aid gear, and the all important T.P. that I keep in it. It has made ALOT of trips with me over the past few months, and it hasn't leaked any. Usually it just gets some water splashed on it, but it has gone through a few HEAVY rain storms as well. I haven't ever opened it and found any water inside. I can't fully explain how happy I am with this case! It is made from thick plastic and should last for many years of use. I will purchase another one so I will have a little more storage.
Seahorse has done a great job on their products!!!!!!

Excellent quality. Bought three colors; they are all my favorite. Strong, accurately made, closure clips are secure yet easy to use. Way beyond the best tool boxes I have ever bought. Would expect to last decades. Just wish Seahorse made storage trays to fit inside, for money, tools, parts, etc. Bought these for grandkids after trying several steel, locking money boxes. Those were nice but only came with two keys and replacements were $25 each. Sent the steel ones back and somehow stumbled onto these at Amazon. If these were advertised beside steel money boxes I believe the steel ones would go out of business. The grandkids will be delighted. They are drilled for padlock lock in center and corners of lid. Only regret is not buying a couple for myself.

Perfectly fits contents of Orion Alert-Locate marine kit. Also fits inside the Seahorse 520 case.

I bought this in SOLAS Orange (International Orange) to contain my boating emergency distress signals.
Boaters (including canoers and kayakers like me) should know that this case perfectly fits the contents of the Orion Alert-Locate marine safety kit, and it seals much more securely than the Orion case that the kit comes in (I threw out my Orion case and use this one instead). FYI, that Orion Alert-Locate kit includes a flare gun, four aerial flares, four handheld marine flares, an orange smoke signal, orange distress flag, chem-light, mirror, and whistle.

This Seahorse 300 case also fits neatly inside the Seahorse 520 case, so if you own both cases, you can transport one case inside the other!

perfect size, keeps the water out

Reviewed in the United States 🇺🇸 on July 29, 2013

Color: OrangeVerified Purchase

i bought this for keeping my water-sensitive items safe while on a canoe trip over the weekend. the inside is big enough (9.5 x 7.3 x 4.1") to carry my wallet, a couple cell phones, rechargeable batteries, lighters and tobacco products, and a Grace Digital ECOXGEAR ECOXBT Bluetooth Speaker , with room for a few other small items as well. the construction of the unit is very solid. hinges are sturdy and the clasps hold tight. the seal was (inadvertently) tested several times throughout the day while in the canoe, and it never let a drop of water in.

the only thing i wish this had was side handles or holes to tie it down with. the only way to tie this off to the canoe and still keep its contents accessible was via the handle, which left it loose to bounce about in rougher water. it's not a big issue, but it may be important to others looking into protective cases.
