The BAT-SAFE LiPo battery charging box is basically like an Ammo box with flame filter. This is more of an overview than review because I am not going to deliberately start a LiPo fire to test it. Not only because it’s unsafe, but also this box wasn’t cheap so I am not going to destroy it for fun :) There are plenty of tests online which I will link to if you are interested in seeing how well it works. Anyway I have been using it on a daily basis for charging and it gives me a peace of mind. In this post will also explain how it works and where you can get one.
Why Do I Need a Bat-Safe Box?
LiPo batteries, while incredibly efficient and powerful, can be dangerous if mishandled or charged improperly. That’s where the Bat-Safe LiPo Charging Box comes in. I have a tutorial explaining how you should handle LiPo properly: https://oscarliang.com/lipo-battery-guide/
As a big fan of Ammo boxes for storing and charging LiPos, I can’t stress enough their importance. These sturdy boxes do a much better job than most LiPo bags out there.
Now, I can almost hear you thinking, “Is this box foolproof?” Well, let’s be real: the only certainties in life are death, taxes, and drone crashes. But in the grand scheme of things, this box is a safer bet than stashing your LiPos in mere LiPo bags. Plus, that nifty filter is great at reducing the smoke damage a battery fire can inflict on your walls.
A word of caution: while the Bat-Safe box is pretty impressive, it isn’t a magic wand. It won’t actively put out the fire but contain it until it eventually burns out. It’s not a replacement for proper fire safety precautions and equipment, such as a trusty fire extinguisher. Remember, folks, do everything you can to ensure safety.

The Bat-Safe LiPo Battery Charging box I bought is the medium size, which is great for regular FPV drone use. Find it here:

Each box comes with a set of instructions and a battery charger holder.

- Fireproof battery safe
- Double steel insulated walls
- Fiberglass and steel wool filter
- Stops flames and intense smoke
- Easy to use latch and seal
- Fire collar grommet for wires to connect from charger to battery
- Magnetically attached mount for the charger
- Piece of mind when charging your batteries
- Lightweight with carrying handle
The Bat-Safe Design
The Bat-Safe box is a sturdy, double-wall insulated steel container, designed to contain the heat of a battery fire.
Instead of completely sealing the container, the BAT-SAFE is vented on top for hot gases and smoke to exit to avoid dangerous build-up of pressure inside. With fiberglass and steel wool filter in place, it can filter out flame and nasty soot.
There’s a latch for securing the lid.
Rubber feet on the bottom.
The box includes a stand for your charger and a rubber grommet with a double seal on the lid, allowing you to pass cables through. This ingenious design lets your charger rest easy on top, with leads running through the box, while your battery sits safely inside.
The Bat-safe boxes are a lot lighter than typical ammo boxes, making them great for storing and transporting batteries too with the elastic band handle on the side.

How Effective is BAT-SAFE
There are plenty of impressive demonstrations of how the BAT-SAFE box contains a battery fire on the internet.Here are a few examples of our Bat-Safe box in action, put to the test by other users:
How to Use?
Setting up the Bat-Safe was a breeze. It comes with an clearly written owner’s manual.
The idea is that you put the LiPo charger on top, run your charge cable down and through a rubber grommet, lock it up and charge your batteries safely inside the box.
The stand for the charger slots neatly onto the top of the box, and the charger rests on top. You might need a strap to hold it in place.
Install the extension wires from the charger to the battery via the grommet on top. Do note that the Bat-Safe doesn’t come with any extension cables for charging your batteries, so you might have to hunt them down separately.
XT60 extension (male to female):
6S balance lead extension (male to female, 6S ones also work for 2S, 3S, 4S batteries):
I am using the HGLRC Thor Pro parallel charging board which conveniently doubles as an extension for me. I do wish my leads were longer though, it’s a bit of a stretch, but it gets the job done.
Once your charger is set up and your wires are fed through, secure the Bat-Safe by fastening the latch, and you’re all set to charge.
Warning: Never leave your battery charging unattended!
Alternatives to Bat-Safe
Now, if you’re not ready to commit to the Bat-Safe, there are other options out there. You could use an ammunition box for sure, which is what I used before I got the Bat-Safe. They’re cheap and also does a decent job, but they don’t have the filter.

For travelling I normally just use LiPo bags because they are convenient to use and lightweight, but they offers little protection against fire.

If you want to protect your property and your belongings around your charging station, the Bat-Safe box is definitely something you should consider. It provides not only a sense of security but a robust solution for storing, transporting, and charging your LiPo batteries.
That said, it’s important to do your own research and decide what’s best for you. The bottom line is, there’s no one-size-fits-all when it comes to battery safety. So whether you choose the Bat-Safe, an ammo box, or a LiPo bag, the golden rule is to always prioritize safety.
