The problem is you're not measuring voltage at the terminal, you're measuring it past the lug....so 160A over a short distance will show a lower voltage
Thanks for the reply. The meter probes were shoved under the shrink tube for convenience. The difference between the actual lung and the terminal would be negligible. It had good contact. Even at a slightly lower reading its amazing how well the voltage holds up. On a lead acid it would have been much lower.
Its not the app. The app just reports the info the battery sends it. In this case the SOC meter is just a counter. SOC meters are rarely perfect and can get out of whack for a number of reasons. One way to calibrate the soc meter is to regularly bring it tò a full charge as dictated by the charger or BMS max settings. Soc cant go past 100. So once the battery is actually full...the full battery and soc meter are synced. Its important to do thisvregularly. If you spend long periods in a mid range your soc meter will become innacurate and you must fully charge to resynch.
I did some research and mosfets seem to be able to operate upwards of 300 to 350F max. I am betting a few more degrees and it probably would have shut down. Ben Stein over at PANBO did a similar test but also applied a heat gun to the terminal. It shut down a little over 200 degrees.
@Spayrex probably some difficult Hazmat regulations. You can see if Roypow delivers there. Roypow basically has the same battery but its blue and cost just a bit more. Will Prowse did a teardown video of one.
Discount code still works. Used it today!
@@ErnieBueno-gq4dg yes it does! Thanks a bunch.
Amazing - good to know what it will really do - thanks for showing that stress test !
Thanks Ron. Cant wait to do the Victron and lithium install.
Does the charger come with, or have to buy in addition?
You have to buy the charger separately.

I’d question an app that says the batter is at 100% when the charger is still putting out it’s max current. Something is not right

The battery was no with like 1 cycle, the percentage shown needs a few cycles to get straight
but 200° for my liking was too hot it shouldv turned off

@@mvintrigue-trawlerdiy1101 oh ok
cant frickn buy that beutifull battery since im from europe :(
Why not? No shipping or some kind of local laws?
@@mvintrigue-trawlerdiy1101 no there is one single website where its sold out and they themself dont ship to europe

@@mvintrigue-trawlerdiy1101 yea i know that but they dont deliver at all nether do they have 12V batterys
@Spayrex dang. Hopefully someone will become a distributor over there.
