Deka03189 Marine Battery Box (Large, Group 27/31), 1 Pack

Very happy. Fits my battery perfectly and is well made.

I mounted twelve of these in parallel on a shed with an office, each to it's own controller, merging all controller outputs, producing 62 amps (13.8 volts @ 62 amps = 885 watts for 4 hrs per day and over 400 watts for an additional 4 hours per day, and a couple of hundred watts for 3 more hours- roughly 500 watts each hour for 11 hours) without aiming directly at sun. I have an 2000 watt inverter to an A/C unit (370 watts) and computer (120 watts) running non-stop 13 hours/day and at 10:00 in the morning the two marine batteries are fully charged. These Topsolar panels are excellent, and I will start making a profit on this setup within two years...even better, my wife is in a full air-conditioned home office and cannot complain about electricity usage :D Highly recommend this product, have another three on top of my camping trailer working perfectly for 1 year and one month.

have this on my kayak stored outside, I've never had to dry anything more than condensation out of it.

It's just a battery box with a strap. But I did like the extra insert that will allow you to use a smaller series battery if you want.

This is listed as heavy duty which is why I purchased this, but it doesn't seem to be. It is identical to one we found locally and the local one was $10 less. It does what we need it to do, but thought we were getting something better than what we could find locally.

This matches my original one and when adding another battery to the boat it did the trick

Another customer previously asked if any hardware was included. The Seller had responded, "Hello, battery box comes with a strap, 2 plastic brackets, and 4 screws". There was no strap, only 1 bracket, and no hardware of any kind. Also, the paperwork ("Picking Ticket") in the box had my correct address, but the name and phone number of a person I've never met. A crazy mixup. So I may not even be able to return it. The box has flimsy construction and I suspect that will not last long. Contacted the seller and waiting for a response... Will update as needed.

Seems a little light weight for the money.. buI guess it does the job.
