SolarBot, Real number was (11) as stated and shown to Will Prowse. These are "Cells" not "Packs". Our "Packs" contain (4-8) Cells depending if it is our (12V) OWL or (24V) Hawk. We have successfully sold another (3,800) of these units from our mass-production line without any issues. We have...

@Will Prowse : I respect your opinion and would love to see you review the mass-produced units that you have been using in your solar trailer. All changes made to the mass-produced version were made prior to your video on the Beta-Version. You have had these for some time now in your solar...

The "OWL" uses 170Ah Lishen Cells V.S. "OWL MAX" uses 202Ah Lishen Cells and includes other bells & whistles. Hope this helps.. - Eric Lundgren : CEO

LithiumLover, Please send me your contact information to Sales@BigBattery.com and cc' Eric@BigBattery.com If you have not already received your order, as the CEO of BigBattery - I am happy to look into this. Just an FYI: If you purchase batteries that are on "Back-Order" that may be why they...

Hello DouglasHHI: It would be a great selling feature, but we are giving them away in units. It's not really meant to be something we profit on - just a 4th added safety feature. - Thank you for your comment. - Eric Lundgren

Hello Solarbot, Good Advice, we have actually spoken with Lishen about it and they claim that these new LiFePO4 cells are in fact able to be installed sideways. Furthermore, After eight (8) months of safety testing, our (12V/Owl) using this Lishen Cell & Design has just been granted UL...

Hello SethRR, I am sorry that you had a bad experience with your recently received battery from our company. 1.) Per our Warranty, your new replacement battery was already shipped out earlier this week. 2.) Our engineering team is awaiting the return of your battery in question to investigate...

DouglasHH, I will find Seth and gladly respond to him. Thank you, Eric Lundgren : CEO BigBattery, Inc.

Gazoo, Thank you for your input. 1.) To prevent damage in shipping, we are now including "This Side Up" and "FRAGILE" stickers to every package. 2.) According to the Lishen LiFePO4 Cell Spec. Sheet: The cells can be installed in any position except for upside down. 3.) Our 12V Owl...

Hey DouglasHHI, Sorry, got busy running this company. Anything I can answer for you? Best, Eric Lundgren : CEO BigBattery.com

Hello Bud Martin: Yes, Seth's pack had the padding installed. No, The pack was not leaking. There was a white-grease stain on the top of the unit but no functional issues were identified. We have already sent Seth a new pack and it's on the way. We honor our return policy and are happy to...

Hello DerpsyDoodler: Yes, you can confirm that I am the CEO by asking Will Prowse. We care and review comments to see if there is anything that we can do better. Thank you, Eric Lundgren : CEO

DouglasHHI: Yes, I agree. I hope Will Prowse does open his units and check. They would be there. They are included in every OWL, HAWK, HUSKY or LiFePO4 Battery that we provide. Thank You, Eric Lundgren BigBattery, Inc.

DerpsyDoodler, Yes, you are correct. What I was referring to is the amount that it costs to get "UL Certified" and the bureaucratic process of attaining this certification are in my mind "BS". We could not agree more.. I agree, Safety should not be a cornered monopoly that stifles fair...

Hello SpongeboB Sinewave, All of our batteries are bottom-balanced and tested prior to MFG and our BMS keeps voltage balanced. If you buy a pack and you see that this is not the case, feel free to return it for a replacement. Thank you.

Hedges, Wherever our battery cables wrap through sheet-metal, the sheet-metal is protected with a rubber ring. This fire-extinguisher is a (4th) safety feature.. Our BMS is the main safety feature and yes, it functions in the format you have stated. We are all about "Constructive Criticism"...

K3nny: You are correct. We are simply not going to be sending BETA Versions out for review. In the future, only Mass-Production for review.

k3nny, You are correct. I would add that the Mass-Production Models with all issues fixed are already in Will's possession in his trailer. The battery tested in Will's last video was the Beta sent to him 4.5 months ago. If anyone has our product, they can see that the mass-production model has...

DerpsyDoodler, You are 100% Correct! UL is BS and designed to keep the little-guys from innovation. We just got our 12V OWL Packs "UL CERTIFIED" and it cost us $260,000 & (6) Months of work! UL is a way for TESLA & LG to maintain dominance selling volumes of antiquated solutions that are hard...

Hello Tbuechner: Actually, it's the exact opposite. Companies are too excited to have "Will Prowse" take a look at their product and send him their "Beta" packs from (4.5) Months prior. We sent Will Prowse our Mass-Production models that are in his trailer now and if he opens those units, he...

Hedges, Do you mean to tell me that eliminating the oxygen in a sealed metal container would not assist in the case of a LiFePO4 fire? We have not been able to get one of our Lishen LiFePO4 batteries to catch on fire - but if we could, this unit would effectively eliminate the oxygen within the...

Hello Solarbot, Just to be clear, we do not advise anyone to puncture our raw cells with a giant metal spear. Nor would I advise anyone to light the gasoline from their gas tank on fire. haha

Mandride: I can assure you that these batteries are secure. The design is correct and all mass-produced models already had issues resolved prior to mass-production. I'd really like Will Prowse to review the (2) mass-produced models in his trailer rather than make a video of a Beta Version sent...

Yes, we laughed about that too.. In the end - the fire was put out even though the bucket was open. The unit works a lot better inside a closed environment as it's sole purpose is to eliminate oxygen from the fire. Thank you for your comment MrNatural22! : )

Hello Hedges: Per our LiFePO4 Batteries that use this fire extinguisher, we were unable to get them to hit thermal runaway in our tests. The fire extinguisher is a (4th) safety feature provided for free in all our new lines of LiFePO4 Batteries that we sell. It auto-ignites at a certain...

Hello LithiumSolar: I hope this can bring some clarity. To be exact, there were (11) Cells with issues out of (10,000) New Lishen Cells purchased from NEC. That is ".0011" of cells having issues which were caught during our (2x) QC Process and never delivered to customers. This was not a...

Hello @upnorthandpersonal , The low-temp cut-off does in fact work. Please have anyone test that has received our mass-production. We have sent many video's of this and happy to post them on our YouTube channel as well. As per the (-30C), you are 100% Correct - We do want anyone using our...

I "LOL'd" when I read this.. Thank you @ghostwriter66 : ) Yes, We are going to have to have some thick-skin when reading all of these comments - but (for the most part) I believe they make us better. We can learn a lot from this Forum (Thanks to Will Prowse) and everyone else who posts our...

Hello Solarwanabe, Yes, These A123 Cells are all Brand New. Here is a picture of the crates in which they came from. : ) We Guarantee you will be happy with them. If you have any questions, feel free to let us know at Sales@BigBattery.com Sincerely, Eric Lundgren : CEO Eric@BigBattery.com

@Sillyputty, This forum doesn't allow me to post a video directly. We will publish it on our YouTube.com channel shortly. You can also eMail me and I am happy to provide. We sent the video to Will Prowse today as well. Thank you, Eric Lundgren : CEO Eric@BigBattery.com

Hello @aaron_c , Here is a link to an independent tester whom reviewed our batteries in our Model-3 Packs: Here is another link of the extraction process for the Model-3 Cells: Please note, NONE of these cells were actually used - they sat in new packs until we extracted and repurposed...

@DKyleM18, Thank you for your feedback, we are striving to offer you better products and the guaranteed best prices in the USA. I welcome any constructive feedback so that we can in-fact get better at our mission. Our goal is to exponentially increase the adoption of more efficient battery...

@kirlos, As the CEO of BigBattery.com, I am happy to answer your post. These batteries cut-off at (-0C) during mass production. They were recently tested to operate well below this temp but we do not recommend doing so and our BMS will not allow them to operate below (-0C). If you would like to...

@Yonkk, Thank you for your video, we have provided you with a $200 credit for the Glue Issue that you had and fixed this in our MFG process. We offered to refund you and replace these batteries but I guess they have been functioning very well for you. Side Note: BatteryEVO, Inc. is our...
