Hey everyone, recently built a 24v battery with the help of Will's resources and the helpful folks here on the forum. I top balanced them to 3.65 in parallel before assembly, but it seems they haven't reached 3.65 upon my next attempt because one cell is lagging behind? This is a jbd bms and the...

This thread concerns the bolts/nuts holding the thick black/blue cables on my JBD 200A BMS. These are 4 AWG cables, and using the information in this thread I established that for my battery, it would be wise to replace this with 2/0 cable. Problem is, these nuts are so tight that there is no...

I've got 8 280ah eve cells connected in parallel. They all came at 3.27volts, so after getting them connected I hooked them up to a 10amp lab DC charger set to 3.65. Important to note that I was only getting 10 watts initially and it's been hovering around 30 watts ever since I crimped some 8ga...

I've established that I want to carry the load in my system with 2/0 awg wire. It's 24 volt 280ah and I want to be able to use a 3000 watt inverter. The JBD BMS I got already has 4 awg wires and lugs attached for two negative leads. I'm wondering if I should replace these with 2/0 awg as well...

So I'm building a 24 volt battery and it looks like the simplest way to do that is straight up 8s, but since these are 280ah cells, that makes for a very long battery. I've noticed 2p4s is used in a lot of videos and documentation. Looks great, but I'm wondering if this changes how I will...

Title says it all. Seems like they don't make a lot of cases for batteries this size. I could throw something together out of wood, but I'm too much of a noob to know do's/don'ts in this regard. Flammability a concern? Breathability? This battery will be living in a vehicle in an off road...

I'm building an off-grid solar system for full time nomadery. It'll need to move at least every two weeks or so. My partner and I will be setting our camp up out of a van and a Jeep Wrangler. The van can't make it into any especially unmaintained NFS/BLM roads, so I was hoping to transport the...

Newbie to the forum here. So my story is that I'm going off-grid because I've got health problems that screwed up my finances and ability to work and I'm looking to be nomadic for a bit while I recover, both physically and financially. I offer this background to explain why I'm jumping in the...
