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.

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 box is very well made, good wiring, mostly quality connections (see below), and perfectly fits the 100ah 12v lifepo4 battery I have. The dual Anderson connectors make this unit perfect for my project. After adding an external waterproof solar charge controller, connected via one anderson connector, some external waterproof lighting, also connected via the other anderson connector, and a pure sine wave inverter, connected on the terminal posts, I have a (more) versatile solar generator which can provide 1200watt-hours of power for much cheaper than a comparable manufactured generator (less than $500 total). My only complaints are the lack of a one-handed carry handle, which was solved with a cheap $8 box strap handle, and the strangely flimsy lighter plug socket which broke literally the first time I plugged something into it, also replaced with a better quality lighted plug for around $8 and 5 minutes (plug and play, no wiring or fabrication needed). Overall I highly recommend.

This is my second purchase. It is a great battery holder with everything you need: fusing, voltage indicator and usb port. I have one in use for a year or so now issue. It holds a battery for one sump pump DIY backup. I purchased the second one for my second sump pump backup.

Set up with a 100ah lifep04 no issues. Installed a renogy wanderer 10a solar charge controller which is small enough to mount inside the lid. Rewired the anderson connectors to the solar charge controller's input / output. Can charge with solar up to 130 watts with this controller which is about the output of a 200w panel, takes about 5 hours to go from 50% to 100%. The output anderson connector can also output 130ish watts for auxiliary 12v lighting, fans, etc. In the cigarette lighter plug on the left I have a 140 watt pd usb-c plug. Then if I really need to charge heavy gear I can use jumper type clamps to the large terminals on the front and use an inverter up to 300 amps so about 4,000 watts max.
