Trolling Motor Smart Battery Box Power Center with USB and DC Ports, Medium

I used to run this box with a 12V 100AH LiTime battery. I have since changed the system to run off a 36V 50 AH group 31 battery from LiTime. I can confirm this box will hold a group 31 battery. It fits like a glove. Just disconnect all 12 V accessories, add a breaker and connect.

very nice product works grate

So, crazy story, I purchase this item to go along with the Inventex 5-person inflatable boat and battery and hook it all up to a trolling motor and hit our lake with my wife during the day. So much fun. Everything works perfectly as it should. We get back to the dock and I tie up the raft and head up to the cabin. Around sunset, I ask her if she wants to go down to watch the sunset and she agrees, so we head down to the dock with a couple of cocktails. The wind had picked up quite a bit and we got some rain earlier, but the rain cleared up but much to our chagrin, it was still on the windier side. But the sunset was beautiful. As we are walking towards the dock, I notice the raft is upside down on our dock. I think to myself, 'our neighbors are so great, they flipped up our raft before it started raining. So kind of them. What lovely neighbors'. We get a little closer and I notice the raft is only 3/4 of the way out of the water and the trolling motor propeller was completely upside down out of the water and spinning like crazy. At first, I thought it was the wind spinning the propeller, but then I thought, the propeller is fixed in gear and shouldn't blow in the wind. As we get on the dock, we realize that the boat had blown over and the Battery Box was completely underwater hanging only by the trolling motor cables 3-feet below the waterline. The trolling motor handle somehow bumped the dock or pole and kicked into gear as the boat blew over and the box (and battery) was completely submerged - but could still see a little blue blinking light of the battery box underwater. I tried to pull the box out of the water by the trolling motor cables, the whole time thinking these cables are going to snap or break at the connection point, but it was so windy that the raft was acting like a sail in the wind and pushing me away from getting at the cables to pull the battery box up. So, I lie down on the dock and try pulling up the 70-pound, completely submerged battery which was pretty much impossible. I needed my wife's help to try and get the battery box out of the water, but was concerned for her safety and wondering how to do this - again, thinking the entire time that the cables were going to snap any moment and the battery box and battery would be at the bottom of the lake. The boat was putting so much pressure on the dock that it completely bent the reel on a fishing rod that was stuck in between. Fast forward past the part where we almost killed ourselves a few times, we finally get the battery box onto the dock, turn off the trolling motor, unhook the cables, open the battery box to find only about an inch of water in the box and the battery, itself, completely unscathed. I brought everything into the garage, dried it all off, let it sit for a couple hours before reassembling everything to recharge the battery from outside the box only to come out the next morning to a full charge and steady indicator light, as if nothing had ever happened! This box is a BEAST! From the strength of the connectors, to the good water-tightness (not waterproof) of the box and to the box's ability to work after being completely underwater for Lord only knows how long, this box is something else. Three lessons I learned: (1) invest in a good battery box (like this one), (2) strap it down tight and (3) never, ever leave your trolling motor hooked up to your inflatable raft that you leave in the water unattended (such a moron). Thankfully, no one got hurt and thanks to the battery box - nothing was damaged or lost and all is in perfect working order. Bam!

My marine battery from Walmart fit well into the case, and it seems nice and sturdy. The only flaw was that the container and the battery came up a nut short on the connectors. I know it seems petty, but I had to dig in the garage. I admit. But come on, guys? Are you all entirely nutless? Otherwise, loved the case so far, will update with canoe test.

Seems to work well so far best one for the money. Fit my group 29 battery great

Trabajo bien. Gracias.

It does fit the LiTime 12.8v 100ah Bluetooth lithium battery if anyone is wondering. Everything works on it as described.

I bought this for my kayak. I absolutely love it! I am so excited to be able to have this on hand.
