6 minute Headway Torture Test - 48Ah LiFePO4 PCB busbars

Correction: On Video I keep calling the headway pack a 64Ah when its a 48Ah pack. It does change some of the statements I make on the video but not enough for me to redo the video- Im lazy.

I just wanna listen to jehu talking all day. Thanks for all you do

[MyDIY]

Jehu,
Thank you for the great quality tests and products. I’m a repeat customer of yours and have both these headways and the LEV60’s. Pretty much all lead acids swapped out now with either LiFePO4 or LTO’s. These things are beasts!

Have you ever thought about putting together a video regarding Battery fires/safety? Have you had any fires?

Nice test! There is no substitute for real-world testing. When I built the first prototype EVSR electric race car, I used 3/8” thick aluminum bus bars, but they would overheat during race conditions (typically 800amp at 160v for as much as a 95% duty cycle, depending on the race track) so I upgraded to 1/2” thick, and that solved the overheating problem.

Ive been looking around for a battery to power a dc/ac inverter. I forgot about your channel and you're probably one of the most qualified especially when it comes to building packs. My question is what cells do you recommend as far as capacity and price? Also don't you sell boards for headway cells? I have to check out your store man wow I haven't been on there in a while!

Idk why I vision you as the guy on This is Sparta Well this video should end the drama.

Electrical installations use parallel cables all the time, EVERY stranded wire is infact parallel wires in a single assembly. Anyone who says you cant use multiple cables just doesnt understand electricity. you will see things like what you did one wire will see different amperage due to length, and connection resistance. But if you get them reasonable to the same lengh the difference can be ignored.

As always, great video Jeh. People using Headway cells for car audio and as you mentioned (in min 9) is connected to the alternator so my question is it safe to connect to it directly ? as I know the alternator when connected to lithium battery (for charging) which has for sure low IR will get fried ? TIA

Fluke 355 True RMS 2000 A Clamp Meter, and it holds its value if you need to resell

Wish i saw these lev60 batteries before i bought my headway bus bars. Still need to buy the cells though maybe i will just go lev60. Very cool videos!

[KuntalGhosh]

buy a uni-t ut221 clamp meter, it is a bit expensive (150$) but it can measure 2000amps dc! . make sure its the ut221 as the ut220 is ac only or the ut222 can measure 2500amps dc.
ut207b & 208b is around 100$ and they measure upto 1000amps dc.
i have the ut204+ and the meter is very accurate and it was 45$ and only does 600amps which is enough for me but not enough for your tests.

Hello I need to know when your website is going to have the 48AH 12V HEADWAY BUSBAR PCB KIT, 1000A CAPABLE! without the blocks in thanks.

Hello friend, I have a 2013 Honda Pilot truck and I want to remove the original battery to change it for a LEV60 since I do not want to sacrifice space, my question is if there would be problems putting the LEB60 battery in the space of the original, that is, under the hood? and what should I take into account

[largepimping]

I think your points/conclusions are valid, but getting temps from those aluminum busbars via a thermal cam can be extremely inaccurate. Teledyne/FLIR has a good article describing this - since I can't add the direct link, you can google "How Does Emissivity Affect Thermal Imaging?" to find it.

[MrMr]

Can i charge the green battery with a car alternator that puts out 14.5vdc?

[nyghtmyst]

Do they come with bms can they be parlled and series in other words can I build a bank you love to talk to you man

[Keith-hzzd]

Do you still have them 4 sale $150 i would like two maybe 3

[mjr]

Hey man you’re hiding the 300 degree spot under the bms 🤣

[alanclark]

I dont won't the headway. Where can i get the other battery?
