:::::::Here is the letter I sent via Intertek's general inquiries form, which required a bunch of personal information (and I took one for the team and supplied actual contact information because I would really like to get the answers to this if they are willing to entertain me, and haven't been inundated with requests for information about this already): | |||

:::::::To whom it may concern, good morning, | |||
::::::: I'm writing to you to ask about your certification for Dragonfly's Battle Born 100AH battery, model BB10012, which is listed in your database here: https://ramuk.intertekconnect.com/webclients/its/dlp/products.nsf/4c8700f3b75987a08525777700583333/8080c4204b23df7d86258b880059c69a?OpenDocument | |||
:::::::For reference, please see this video by Will Prowse: https://www.youtube.com/watch?v=2m7DSCKO-Bo&list=PL7bvIB2TPsCgD4TxUxf3szWyxRz_HwUd1&index=5&pp=iAQB - it's part of a larger Battle Born review and testing series, and I will summarize this for you since I respect your time. | |||
:::::::Will tested a brand new Battle Born BB10012 model battery, charging at 49A, through cycle testing in accordance with the battery's specifications (charged at -1A of the rated 50A, discharged at 99A, -1A from the max discharge of 100A). He was trying to test for a repeatedly-reported issue with the battery: that the positive terminal is bolted to its bus using aluminum bolts with a plastic spacer (PA-765), which deforms under the heat load of current passing through the bolt and nuts, and result in a loose terminal. However, what happened during his testing (after he had to lower the testing specifications because the battery was disconnecting when cycled at its advertised rate) was that the negative side of the battery heated up so badly after 30 cycles (far fewer than the 3,000-5,000 cycles advertised by the company) that it deformed the battery's case and the battery completely ceased to function. | |||
:::::::Please see this site for a full written explanation of the situation, including other technical research, from Louis Rossmann: https://consumerrights.wiki/w/User:Louis/Dragonfly_Energy_trade_libel_suit_Will_Prowse | |||
:::::::I have a few questions about your certification of the BB10012 battery. | |||
:::::::o Did you actually test the BB10012 100AH, 12V battery? | |||
:::::::o Were you able to cycle the BB10012 between 3,000 and 5,000 times at the stated charge/discharge capacities without failure, overheating, deformations, or other safety issues occuring? | |||
:::::::o If so, was the plastic spacer used in the connection of the positive terminal present in the model that you tested? | |||
:::::::o If so, could you explain how a plastic spacer that deforms and leads to loose connections (not "disconnects" as the manufacturer claims) could still conform to a safety standard? | |||
:::::::o Do you require companies that make changes to their products to retest with you, or submit their changes to you for review? | |||
:::::::o If so, are there any changes that are considered minor enough to not require retesting/recertification? | |||
:::::::o If so, do you have any kind of guidelines as to what would characterize a change as "minor" in this sense? | |||
:::::::o Would the insertion of a PA-765 spacer within the assembly of the positive terminal's connection to the bus be qualified as a "minor" change, or would it require you to retest the unit? [[User:Jackalgirl|Jackalgirl]] ([[User talk:Jackalgirl|talk]]) 16:38, 9 June 2026 (UTC) | |||
::::::Also, with respect to the "what do these words mean", Will says it specifically at 6:06 in https://www.youtube.com/watch?v=m5qQYGLi4B8&list=PL7bvIB2TPsCgD4TxUxf3szWyxRz_HwUd1&index=7 - "Also, on this sticker it says, 'conforms', 'certified', and 'conforms'; that does not mean 'UL Listed', that means it's conforming to a standard, probably with a third-party lab."
