Aluminum Camper Forum

Response:

Thank you for contacting us. We appreciate the opportunity to provide technical context regarding the engineering and safety of your system. We understand there are conversations circulating externally, and we want to support you with facts about how our products are engineered and certified.

Regarding the concerns you raised:

Battle Born Batteries have been available in the market for more than a decade. During that time, we have delivered well over 400,000 batteries into service across all major markets. Our solutions have undergone extensive third-party testing to UL standards, we operate an open production process in the United States, and we routinely provide tours, published videos, and engineering transparency. These outcomes and the long track record of safe operation speak for themselves.

To address questions that have recently surfaced about terminal heating and fastener design, it is important to highlight that what some observers view as a failure is a safety device working exactly as intended. The aluminum nut used in our 100Ah packs' positive terminal is a purpose-built thermal failsafe. It is engineered so that the plastic deforms and disconnects when excess heat is present at the terminal.

This protects the internal cell structure by interrupting the current, preventing further heat buildup and thermal runaway. This safeguard exists for conditions created in the field such as loose external connections, systems operating outside specification, or uncontrolled short circuits. It is one of several intentional protective mechanisms within our packs and is necessary for our UL Listing Standards.

The key takeaway is this: This design prevents heat from migrating into the cell stack, meaning it is designed to stop conditions that could otherwise create a thermal runaway event. It works as a sacrificial barrier that takes the heat event on behalf of the cells. That is the exact purpose of the feature.

In cases where a pack has already experienced misuse or improper installation, visible damage at the terminal is typically the result of that safety mechanism activating. That does not mean the design is flawed. It means the protective feature served its purpose. The batteries we sell and support today use the same trusted and validated design that has been in successful field service for many years.

If you are currently experiencing a specific operational issue with your system, please reply with photos of your installation so we can assist you further.

Sincerely,

It was yesterday morning.

I tried contacting BB to get their opinion on this issue, couldn't get through.

Ack! I've got 4 of these in an off grid solar system.

Do you know when Will did this video. I couldn't find a date on it.

Hello,

Owning a new Battle Born 100 amp hour battery, this not what I wanted to see.

Fire hazard due to loose internal positive connection?

Those inputs/outputs will be a challenge for our site too. We'll have no hookups, but the property has a hand pump well, a shed with a composting toilet, and we have 220 watts of solar. We also have a portable waste tank on a small trailer and there is a public campground 10 minutes away that charges $5 to use their dump station. This all may prove to be too much of a challenge, but we'll give it a try.

I have been camping for two months in the Keys in February and March for the last few years.  I can't think of any issues that have come up over the times I have been doing this*.  I think the humidity issues occur while winter camping when you get below freezing temperatures. 

*We don't always get FHUs so water, gray water, black tank and power management is the challenge when dry camping. 

Good intel on the humidity. Our intended campsite is lakefront on Lake Michigan so it will be a high humidity spot. I'll figure out something to mitigate it.

We have nice mattresses from Mattress Insider that have held up well for 11 years. I'll check to make sure no mildew sneaks up on us.

We've taken our 21BHS out for several 1 - 2 month trips over the last three years.  We also stay locally sometimes a month at a time with a couple of weeks in between stays. 

The first long trip we made, we discovered that our A/C (the original Penguin 2) could not be trusted as it was freezing up.  We replaced it with the A/C from RECPro (which I believe you already did).  The big benefit from that change (aside from the fact it is a nice and quiet A/C) is the heat pump.  We never realized how handy that can be on a long trip.

The other thing that makes a difference is the dehumidifier we bring along.  I store it in the back seat area of my truck and then carry it into the camper and plug it in near the slide area.  Works great, keeps the humidity down and also prevents any musty smells from taking over.

Other than that, the camper has been great as is for long trips.  How is your mattress?  That would be the only other consideration I can think of.

This coming summer we plan to park our camper at some property we own and use it for extended stays; perhaps as long as a few weeks at a time. However, the camper itself will be at the property for most of the summer as we come and go. For those of you that have done extended stays or use a seasonal campsite, is there anything special we should think about for this type of use?

What's the crank on the upper part of the top pantry for?

The first owner had an upgraded directional TV antenna installed.  I would have been fine with the original one.
