what do you propose?

You mean C- and B-? At least that’s what’s on mine. It measures .21v. I just rechecked and yea now it’s saying 13.2v after the BMS and 13.5v before.

i just assembled the battery so no it hasn't been hooked up to anything, although I just was messing with my temperature controller and silicon heating pad to get the settings right so now the voltage of the batt is 13.5v while the terminal lugs post-BMS are reading 12.99v. This is my second...

Hmm yea now after using my batt a bit the measurements are 12.99 from the lugs after BMS and 13.5v before the BMS lol seems like mines maybe shot?

I saw somewhere that .1- .5 voltage drop is normal? How can I check to see my BMS is ok? The BMS itself reads the correct voltage of my battery it’s only after the BMS that the voltage drops .3v.

just sitting yea. Idk if the connections after the BMS aren't perfect, the BMS is going bad, or if this is completley normal lol

In the BMS app for the Overkill it reads out 14.4v and all cells at 3.6v as my multimeter does, but then past the BMS at my actual terminal lugs it reads 14.12v. Is the BMS supposed to drop the voltage like that?

what can happen if you raise the voltage while the batt is still connected?

I used 8awg.

I had my charger set to 3.6v but coming into the third week of top balancing I decided to up the voltage since my cells were barely charging (like .001v a day if that.) I read here and there that the absolute max a lifepo4 could be charged to was 4.2v and so thought setting the charger to 3.8v...

great thank you for the info much appreciated ?

okay thank you. sounds like i have a ways to go then lol. I'm getting it shipped to OR so I'm right near the west coast.

I ordered early October during a Chinese holiday and so got confirmation that my order was processed by Docan and sent out Oct 8 after their week long holiday. Allen He said that my cells were in the container and waiting for the ship as of 10/22. Just wondering what the average wait time is...

okay sounds good thank you. I'm considering sitting the box on top of a sheet of rubber for the vibration issue but someone else recommended EVA foam which seems to be a better fit.

thank you for this. I'll consider EVA over fr4 for what I put between the cells :) While we're at it do you have any recommended metal casings I can put the cells in? Should they definitely be put into a metal box? Some of the enclosures I've seen on here are pretty open and are mostly just two...
