Battle Born Battery Issue

[Powder Hounds]

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?

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.

It was yesterday morning.

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

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,

[Powder Hounds]

I personally dont't buy that response, sorry, melted plastic is not a fuse!

Also, let's blame it on the user! Typical crap!

My new Battle Born battery will be provided to a recycling depot for disposal, ordering a Chinese Li Time battery in the spring to replace this liability.

Huge disappointment with this company, we all got scammed!

Be safe!

[Merlin]

Same here. I'll be installing 4 new batteries of some other brand at my cabin this spring. That potentially internal loose bolt with intermittent connection in the Battle Born is absolutely unacceptable and could cause electrical damage to other equipment even if it doesn't cause a fire. I hope anyone experiencing the problem reports it to the Consumer Products Safety Commission because that's the only way to get Dragonfly Energy to take action.

And powder hounds, thanks for bringing this to the forum. I passed it along to a Land Cruiser forum where I'm an active member. Some other members do have Battle Born batteries as house batteries in their overlanding setups.

This situation with BB is shedding light on how bad their design and service actually is. Customers are now posting information on their personal experiences trying to obtain warranty coverage on failed batteries. Shipping fees, service fees, return charges, only to diagnose a now known issue? You can purchase a new Chinese battery for the same amount of these fees. Makes no sense.

I really hope all individuals who have purchased these make the decision to get rid of them.

Recently I inspected the red epoxy on the positive terminal blade, it is already showing darkening from the original bright red.


Ordered a Li Time to replace this piece of junk.

[Merlin]

Lots of reasonably priced batteries now. Any particular reason you went with Li Time? I have read good things about them.

[Powder Hounds]

Hi Merlin,

Main reason was Li Time has a distribution centre here in Canada, British Columbia. Easy purchase, no tariffs or extra taxes.

Performance wise, 140 Ah is perfect for our requirements. Fits in our armour battery box. IP65 rating, cold weather disconnect is essential. Big plus, those extra amps would also help in the future. If something happened to our fridge and we had to look at a 12 v unit I think we could manage with 140 Ah. The Bluetooth connectivity is nice but wasn't a factor as we have the Victron smart shunt. But, the Li Time app does have a battery temperature measurement that would be beneficial for sure.

The main reason I purchased the BB, was they have a true self heating function. Also, I wanted to support a North American company. I don't have that same outlook now.

In cold weather it was easy to just to turn on the toggle switch to engage the heating pads. No external power required! Having an external power source to connect to the battery to engage this function didn't work for us. I will keep all the BB heating jumper cables and switch in place so that I could add a silicone low wattage heating pad to the Li Time if I determine there is a need.

With the extra amps we can just wait a while for conditions to warm up before the charging cycle can begin. I do add automotive insulation to the battery case,  just to help in near freezing temps.

Bluetti does have some new RV/ trolling batteries that I looked at, B1210. Modular with com ports for expansion, features we wouldn't use, but for off grid they would be nice.

Things just matched up. Fingers crossed.

Good luck with your selection.

I ditched my new Battle Born this week. Could not bring myself to even giving it away to anyone. Terrible situation for people who purchased these with hard earned money. I hope they go out of business soon!

This was recently posted. Do you really want to keep using these batteries?
