740, I appreciate your input and taking the time to review my system.

740, here's the current SCC setup.

740, unfortunately my system is in my RV at a storage facility. I will be making a trip out tomorrow and can get the controller settings. Thx for your response.

Hello Bently, you are correct, I have 2 BMS's. I am fairly new to solar and should have realized that the power would be split between the 2. Thx for the help and for not beating up on me, God knows I had it coming.

Hello, hoping I am just missing something here. My setup, 2 x 100ah packs, in parallel. 2 x 200w panels in series. Victron controller showing at least 20amps going into bank (I have the controller set to 20a max atm). JK BMS showing maybe 10amps, avg closer to 8amps . Any ideas on where to...

I just realized that I am not sure how to set up. Is the BMS that I am calibrating going to the positive cable that is going to my discharge device? I suppost there is no way to get current readings for both batteries without resetting the test on the other posts.

I could, but it most likely wouldn't see much use beyond my current packs.

Probably more expensive than my cells, don't think I could get that past the CFO (my wife)

Thx for that, I am hitting up friends to see who has a clamp meter. Appreciate you help.

Not sure how I would test for that.

I forgot that you can do that with the JK, I will throw a meter on the cables and see what I come up with. Thx for that.

WIres identical, crimps good, bms showing simialr resistance on balance wires. Afirm on feeding the load from both batteries.

Hello, I just hooked up 2 LIFEPO4 100ah packs, connected in parallel, 2 JK BMS's. Both packs were just top balanced and allowed to rest for 2 days, settling within .08v of each other. I decided to do a discharge test down to 50% of capacity. I started with a 10amp draw and noticed right away an...

Yep, already got a replacement.

on the pack I was getting 13.3v, with the balance leads connected I only got 10.9 at P-

Thx for the replies, I guess I may have just had a bad BMS. Couldn't get to to wake no matter what I tried.

Good info Sunshine, thx. I had a BMS on one pack fail after discharging 30amps., guess I need to pay attention to my initial setup. Still kinda new to all the subtleties with proper battery configs.

Hello, I heard that having 2 4s packs in parallel, each with a BMS, is not the best configuration. I have read that there can be a feedback or surge situation that can take out one of the BMS's. Anyone have any info on this setup?

Kerosene, what a great idea. I assume it's way more expensive than diesel, but if you only are using in super cold temps what the the heck. I imagine it's cleaner than diesel (used in jets) so probably less carbon/soot?

Anyone using additives for cold weather for their diesel heaters? I read that diesel starts to gel around 10 degrees F and can cuase a lot of issues.

Just to expound on your "warranty" post, one of your posts said that your Tech stated there was nothing wrong with the battery. Yet your "policy" begins with "If WE are unsure if a product is faulty" you will cover the cost of shipping. You can't have it both ways (let me guess, you did this out...

Well, again not true, My contact at SOK Canada requested that you get involved. A couple of points that you have left out. YOU requested that I send my battery back to you for testing, and even paid for the shipping to do so. Is that in your "policy", didn't think so. It seemed to me that you...

That's funny, its nice to see someone with a sense of humor. I had completely put these folks in the rear view mirror until they initiated contact again. Hopefully they stay gone this time..

Nice words, you failed to say that you were keeping my battery after your testing, which you requested, until I paid for return shipping. Your wanting to test the battery was all that was discussed with me, not a huge shipping charge for me to receive MY battery back. I guess you forgot that...

This coming from someone who apologized to me about the advice and treatment from one of his Techs. I Never threatned anyone with a chargeback, which he has never explained, he just seems to throw words around to see if it sticks. I did say that if I could not return the battery for a refund I...

Gavin, never heard that after a week of troubleshooting with SOK. Good to know, if I ever get someone to warranty replace mine I will ask for the non-heated. Thx for the heads up.

Sparky, you are correct, after a week working with SOK, they directed me to CurrentConnected. Have been trying to get a hold of someone there, strangly their phone system says they are closed.

I have had one 100ah SOK BT/non-heated battery from SOK, that for the past year, has been great. Decided to get another one 3 months ago and went with the heated version. I hooked them up in parallel and had discharged around 40amps, with a 10amp draw, both BMS BT radios reporting 5 amps being...

Thx for the replies, I could not find that info, much appreciated

Hello, just wondering if anyone knows at what temp the SOK BMS fires up the thermal pads. I can't find any information out there.

Thanks for the response, it would seem I have run into the limitations of my system. I think I am going to do like you are doing, I do have another 200w of flexable panels, probably add them to another 100|20 controller I have, that way I can direct those panels to get a good angle and squeeze...

Yes, it was about 60% SOC. Am I to assume that under ideal conditions that I will see roughly 80% of the rated 400w or 33amps at the controller?

Hello, I have a question about panel output. I realize there are a lot of variables, angle, clouds, altitude, etc. I have 2 200w Bouge panels. I currently have them in series and am getting 45v at the MC4 connectors at the controller. According to the Victron app for the 100|30 controller I am...

Thx much, appreciate the help. Hope you have a good evening.

So, beyond the intense math, can I assume that I will not damage my controller?
