Review: Group 31 (Battery Size) - bottom tray w/strap - Battery sizes can be complicated, I didn't even know what group 31 means but I found out that it is the size of our RV's cab battery. I didn't like where the battery sits natively so I purchased the plastic bottom and strap to better secure it's position. Voila`, this was a terrific solution that fit my needs. I am thrilled with the purchase and feel it was a great value overall. The build quality, durabilty, and expected life of the components is solid and unpredictable unless damaged. The fit and ease of installation were the final part of satisfaction making this a great deal and easy to recommend to others.
Review: Love lighter weight, good aH time - Combined with good aH time and likely much longer life, the lighter battery is easier for an aged man to handle. Hardest job was replacing smaller base box with a larger one. Battery is great and worth the higher price.

### ⭐⭐⭐⭐⭐ Wow just wow the best battery box ever
*by E***D on April 20, 2022*

This is the strongest, well thought out battery box I have ever seen and with all the baots I have owned and do own I have seen many. The strap is nice and feels real nice and the clip is great, love the logo on the strap and the 4 end mounting points are so strong you don't need centers because the way its designed, less holes in a boat the better. I purchase the group 31 for my group 29 battery for my new trolling motor on my 17 carolina skiff. I also purchased the group 27 for my 2020 enclosed 22 ft car trailer that I run a small TV, led lite strip with outlets and 3.1 phone charger ports with an inverter. I will be upgrading my inverter and be buying 3 more group 27 battery trays for the trailer so i can run a microwave and mini fridge when taking the quads out or traveling.. I will also order another 2 for my caolina skiff,s 2 rear batteries. I purchased there marine onboard genius 5x2 for the boats rear batteries and upfront for the trolling motor there was a previous installed guest charger. My 2020 2500 ram diesel has a marine genius pro 10x1 for the fual batteries in parellel and keeps them evenly topped off at 13.18 volts in maintainer mode. Liked the onboard chargers so much I also purchased the Geniuse 10 amp portable charger and the very nice carrying case along with a pack of 20 toy battery quick connects to permanent install the quick plug so I can hook up the 10 amp to any of them and charge each one every month. I'm considering buying the 1 amp maintainer for all my toys and ride on mower. I can't say enough about the NOKO brand and these battery boxes honestly I wasn't expecting much they were cheaper then any others on Amazon but when it arrived I was extremely impressed. Will be buying more and NOKO customer for life fpr all my battery needs!!! No I'm not a sponsor but!!!!! If NOKO wants to sponsor me and my boat so I can travel around the United States and win fishing tournaments and show off NOKO products please do so and contact me!!
