Smart Battery Box, 12V Marine Case w/ 50AMP Connectors, Multi Ports & Circuit Breaker for Trolling Motor, RV & Solar Panel, Battery Not Included

Lots of good features and everything seems to work well. I am using 3 of these to power my 36 VDC electric outboard. The built-in Anderson connectors are a big plus - they will make my series connection of 3-12 VDC 100 Amp LiPO4 batteries a snap. The built-in volt meters seem to be reasonably accurate (+/- 0.1 volt). The main reason I went with 12 VDC batteries instead of 36 volt was to have the power center type advantages of 12 volt which these boxes readily provide with the USB and cigarette lighter plug features. This way I can use the battery packs to power lights, bilge pump and device recharging. Given these accessories, and the complete wiring provided, I would say that this product delivers in terms of functionality and value. Thank you All Top for a quality product.

I ordered this battery box for my 100 amp hour life po battery. I wasn't sure if it would fit or not but it indeed does fit and this box is fantastic it looks really nice and has some really great built-in features. The voltage meter seems to work great even with the life po battery.

This works well, but it needs four improvements. First, the Anderson connectors are not even water resistant. There are good Anderson connections that are meant for water/rainy environments that offer better protection and a decent IPX rating and this box should be using a more water resistant connector. Second, there is no provision for bolting down the unit. It needs at least 10mm - 5/8” bolt holes at each corner and the middle outside the main compartment. The case needs to be lockable. Already had someone try to steal the battery out of mine. Last, the external terminals are fine but there is nothing in the documentation as to size. They require an M10 ring connector.Otherwise is works fine and is very useful. They need to move to PD spec USB-C (100W) or at least provide for it, but the USB they do have does work OK for basic recharging. I won’t complain too much about the tendency to gather water inside as many battery types need to vent. It would be nice if it were more water resistant— something they could do with some slight lots to the top. I’d buy it again, but it could be so much better.

Great item and seller. Did have a failure just before warranty ended. Prompt exchange for new item. Great support.

Great set up.

Sturdy well made. Great solution for a portable battery. Keeps the battery protected. It has all the right power connections.

The ports and switch work great. The top is not nearly as secure as expected. It is only held on with the strap, which itself wants to work loose as you move it around. A handle in the middle would also be very useful. I take my lithium battery camping, and this is definitely better than it hanging out unprotected, but it seems like it should be better.

Really handy! Use them for my Jon Boat. Nice to see battery voltage deans plug makes it so simple. I used pool noodles to fill in gap so I didnt need a big heavy battery to fill it. Enough space then to throw a set of jumpers in it so i can charge them for the longer days on the water
