Picked up these watertight boxes from Walmart tonight. Made by Outdoor Products, Watertight Box-Small. Added .5 inch of closed cell foam to front and back and .5 inch egg crate foam to top to hold batteries securely. The cases will hold seven 18650 batteries per row and will stack four rows high for a total of 28 batteries. Rubber seal to make watertight, cam latches, and steel rod in hinges. Cost $5.88 each and are a cheap alternative to a Pelican case. The blue case is packed with 28 batteries and the orange one with 7 to show capacity.
Found them in the sporting goods section between the insulated bottles and backpacks. Also found them on Amazon but at a cost of $15.
Wow, nice boxes, these look very well made and sturdy.
(Not like the boxes at DX I took a look at recently.)
For the price I think they are sturdy, both fell out of the shopping cart with no damage while shopping, dropped maybe 4 feet. Are they Pelican sturdy, no way.
Aww, what happened to buggy?
Figured that was a southern slang word so I changed it, didn’t know if anyone would know what a buggy was.
Nice usa dialect map
a. shopping cart (77.02%)
b. shopping wagon (0.22%)
c. grocery cart (13.95%)
d. shopping carriage (0.22%)
e. carriage (0.95%)
f. buggy (4.11%)
g. supermarket trolley (0.23%)
h. other (3.29%)
Only 3 I have ever heard are shopping cart, grocery cart, and buggy. Buggy is in 3rd place with only 4%, I was right, it’s concentrated in the southeast. New Englanders call it everything.
Can you give a few measurements. Mostly outside
Just walking around Walmart tossing items into my other. 
Thanks. Those look like a neat little rig. I don’t feel I need pelican case quality to protect my Chinese batteries! Gonna hit walmart and get two too!
+1, Im going to check out Walmart, hope to get one or two if they are a reasonable price in Canada.
Ive always liked little boxes and storage containers.
Unknown. I had to scroll up to get it.
Nice find Southland. Thank you.
