Okay. Sick of these stupid headway cells. Cell one is completely dead. Zero volts. Apply a charge and it takes no current. This is my third set from battery hookup. I just using them to test BMS’ so they get no use.

I just swapped my BMS and one getting the same thing. I wonder if the balance wire got too hot, melted and now isn’t making good contact. Im going to take apart the connector to have a look. I am running the stock balance harness as I’m running 8s and can’t use the pcb that shipped with the eel...

I just noticed this. The BMS isn’t reading cell one anymore. I just disassembled the entire pack and hooked it up to a different set and I still can’t get a reading on cell 1. I can read the voltages on the connector so it’s something in the BMS.

FYI I attempted to connect over wifi and no go. Some other forum posts hint at an ethernet connection, so I may try that. I'm not installing it near the inverter or energy meter so I'd like to avoid running an RS485 connection. I'm run an ethernet cable this week to see will work and will report...

I just picked up a full EV (traded in my phev and got a great deal on a Chevy Bolt EUV). I already have a level 2 evse but I've had my eye on the solaredge unit because the data will be in the same mySolaredge app plus it has Charge Via excess solar only options. My PHEV had a max of 4kw I think...

I was trying to lighten the mood with a bit of humor. In all honesty, it’s pretty bad but people shouldn’t really be surprised. We shouldn’t be buying this stuff expecting great support. We are paying fractions of the price by making our own batteries and expectations should be low. It’s shitty...

Send a unit to Off Grid Garage and have him make a video. It’ll be fixed in a few days lol

Damn I might buy a few. 75 (64 if you buy a pallet) bucks for a 370W panel! Hell I may buy more than a few. I have a whole west roof left for expansion.

I bought 25 Jinko panels from them locally and they have been great for 3+ years now. Don’t know about shipping though. When I bought they were working out of a large house with panels stored outside. That could be different now.

https://www.jkbms.net/download_pc has a version 15.11 firmware out now. Maybe it was a bug they fixed.

Yes, you'll need either a raspi with venus and a third party can adapter, or just buy a cerbo, or venus, or any other GX device with native built in CAN. You'll be better in the long run with software updates (imho)

Shipping will kill you. I got the whole kit minus BMS.

434 without the BMS.

I got my busbars from eel and they actually have a nut embedded for voltage sense/balance wires! Very cool!!

Lunar new year is over in china so I got a reply in the heating function from JK: For instructions on heating cables, the green 5PIN cable of the heating cable needs to be linked to the heating pad, and the rest of the black and red cables are linked to the smart charger (after the smart...

one sold.

No screen is a selling feature. I honestly couldn't care less about a screen when there is a bluetooth app and CAN comms.

It came with the kit. All the cables were premade.

Did a rough assembly of the BMS onto the front panel. The cable CAN work just wish it was a bit shorter. Also did anyone hear about this heater cable? Was is the red and black cable for?

I’ve had the series pad connected for about 30 min and it’s hardly warm. I cut the series connection and put them in parallel it’s much better. It’s noticeable warmer but still able to leave my hand on the pad as it’s distributed over a wider area. I think this should be good enough as I...

1. I was thinking the same thing, however this 30 or 60w will be distributed over a larger surface area so I figured that it would probably heat much slower and less direct so it wouldn't have the same impact as a lightbulb with the resistor over less than an inch. 2. No, not all the time. It's...

I'll be installing a 8sp2 system into an EEL server rack battery box for a 24 system with the new JK BMS inverter BMS. EEL sells heating pads (designed for 48v systems) that has two pads in series. I figured the lower voltage should just halve the power. I measured the resistance and it's around...

Also the cables included were crimped the wrong way so they don’t fit into the breaker the correct way (it should be flipped 90degrees). Also the cable from the breaker to the terminal is too long. I am probably going to upsize these cables anyway as I have a 200amp BMS and I’ll be...

Eel said they were included. I specifically asked about them and wanted them to ship before the Chinese new year as I have a van trip planned for April. It’s going to be tight.

And they didn’t include the busbars!!! Here are the cables included. 4awg and the negative is 2 7awg.

Eel battery box arrived

I assume you have an active BMS. Do you have the wifi module or do you use the PC software for programming? If you have neither, you can get an opensource module from aaronb https://github.com/aaronsb/REC-BMSManager. wifi module will be much easier if you are a novice as it's a whole screen in...

I've made the decision to go from 12v to 24v so I no longer have a need for my 400a class t fuses. I have two. Looking to get $40 shipped each.

Price is obo within reason.

Also since I had my battery setup, I ran some tests. I had to push 1.5amps through my power supply to get ANY current to show up in the BMS (it was showing .4amps). I email JK and haven't heard anything. This is similar to what Andy had as well. The shunts they install aren't very accurate. I'm...

Version 2.7.0.22 of the PC software is out. http://www.jkbms.net/download_pc

Had a rare power outage in Vegas. My solar is grid tie only so I got this wired up to run the office until the power came back up.

FYI Helen from JK emailed me (I didn't email them, they must have reached out to buyers of the new bms) and she included the 14.19 firmware with release notes: -V14.17 Upgrade logs 1.Fixed a bug where parameters were lost after BMS restart. The bug is caused by a logical error in the...

looks like 14.19 is out. No release notes on their site. They must just send them only to Andy ;)

Interesting, I'm curious what the difference is between hardware versions.
