Important to me is that this box has a moveable separator for multiple sized batteries. Since my LiFePo4 battery is not a standard size as a traditional battery, it helps to keep the battery in place.
With that said, it is also possible to install a second smaller battery on the other side of the battery (like a SLA or gel-cell [i.e. NOT a battery that can leak fluid/acid], that way you can use it for charging cell phones, accessories, etc. without taking power away from the main user like my radio!
Works very well
1. It does have a divider and some grooved slats, but the divider is not solid. It should help keep a size 24 battery from sliding around. I might put a small battery maintainer in the empty space.
2. It comes with a strap, but its not obvious not to tighten it down (my pictures might help). It also comes with two mounting clamps that you screw into the side of your boat/whatever that I'm assuming you pass the strap through to the the entire thing secure. This is still a nice bonus because the didn't have to include it.
3. It has top vents. Probably because Hydrogen is light and will fill the top of any space so thats why almost all battery cases have top vents. It has small plastic vent covers with a spacer that will probably break off over time leave open vent slats. But still nice try to reduce water entering.
Still a great deal for what you get.

ちなみにM31MFは12Vの115Ahが定格ですので、Whで言うなら1380Wh。
ハヤりのポタ電(3.6V)風に表示するなら、約38万3千mAh。
といううことはこのハコ(0.2万円)、M31MF(1.3万円)、2kWインバータ(1万弱)、充電器(0.2万円)、プラスアルファのお手持ちの配線資材やら、の計3万円弱で、15万円クラスのポタ電と同様のものが作れちゃいます。未来がこんなところに。
(ちなみに当方北海道在住ですが、リチウムな市販ポタ電では冬場(低温時)まったくお話にならないところ、鉛電池であればかなりまともに使えます。)
…が。重いんですよ。えーもう、死ぬほど重いです。
多分2kg程度の周辺資材を除くとしても、M31MF単体でさえ公称25.5kg。
さっすがアメリカ製の当ケース、アチラの人種なら歯ぁ光らせて「HAHAHA!」とか言いながらヒョイっとモテる、いや、持てるのかも知れませんが(偏見)、貧弱なアジア人にはちょいとキビしい質量でございます。
しかもたいてい、この手のものって床(地面)の高さに置きますから、運ぶときはそれを腰の高さまで持ち上げて…。
面白がって作るのは止めませんが、その前に、米3袋、または1.5Lペットボトル6本カートン3箱、あたりに相当する質量ののカタマリを、自分は容易に運べるのか?というのをよーく考えることをおすすめします…。
(なお、死ぬ思いで持ち上げてみたところ、取っ手なども含めた意味でハコそのものの強度にはまったく不安がありません。さっすがアメリカ製。)
It has accommodating gaps in the lid to allow for the cables to come out.
