ALL-TOP 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.

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

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.

The media could not be loaded. Muy buena calidad

I put a 100ah Lipo4 batt in here to power my 991 or my FT-2980 on field day or pota trips.Also ran a 12v fan and a few 12v tent lights to illuminate my work area. Its pretty handy.If 100ah is not enough reserve power for portable ops, I'd recommend getting one of those stackable toolbox rigs from Menards, Lowes, or wherever, there are a half dozen brands or more and you can customize them with whatever outlets, meters or whatever you need.

Battery strap falling apart right away

Ordered this product for myself and was excited about it, when it came the buckle was broken. All it took was one email and they’re shipping me a new one. I would definitely recommend getting anything from all top.
