Yeah ??Yeah that's what I meant by my post, you're paying an upcharge just for the better support
Sounds good thank you, I'm going to order these ones thenWith the JK, you might save some money in the long run.
Quite some people with jbd/overkill add an active balancer later.
JK had that already build-in.
Thank you for the link. I have a little trouble with it though, how is it verified that these aren't knock offs? The reviews are awfully suspect to meLots of JK options here.
I'm happy with my 3 JBD 7s-21s, besides balancing.

They are a reputable storefront on ali... I found the one I linked from links in this thread.Thank you for the link. I have a little trouble with it though, how is it verified that these aren't knock offs? The reviews are awfully suspect to me
Thank you very much, it is very hard to tell from mobile who the seller was on aliexpress so I wasn't sure. I'll check it out tomorrow from a desktop.They are a reputable storefront on ali... I found the one I linked from links in this thread.
JK BMS Deal AliExpress
JK BMS If you're looking to snag a JK BMS for only $108 from a known (reliable) seller of these on AliExpress check out the link above. It's a promotion that only allows you to purchase one at a time. I just bought 4 via separate transactions. Not sure if they will catch that or shut it down...diysolarforum.com
Overkill uses JBD. I have three 250A JBD BMSs and they are all great. I would buy them again.Wow, that's a strong opinion!
What would you recommend? I know that the Overkill BMS is well regarded but I was hoping to avoid that price tag.
Missed the question apparently.Overkill uses JBD. I have three 250A JBD BMSs and they are all great. I would buy them again.
You didn't answer the question: How much current do you need your BMS to handle?
I would definitely use more than a 60A BMS for that inverter. You want one rated higher than the max current you could draw. 100A should be fine.Missed the question apparently.
I was aiming at 100 amp BMSs just because that supports 1C rate on the batteries, but I suppose a 60 amp BMS basically gets me to max capacity for the 3kW EG4 inverter I'm eyeing for this project.

Shop around a bit... You should be able to get a 5k from the OEM for ~$600 shipped.While an impressive piece of hardware, a Sol Ark 15k is a nearly $7000 inverter, and I'm looking at the $700 EG4 3k. I can't spend an order of magnitude more on the inverter. I have no need of future proofing my batteries for a monstrous inverter like the 15k. If I ever get to a fully self sufficient state that would require something like that, I'll surely have better batteries than these to make it happen.
With two batteries in parallel, I'd use two 100A BMSs. That way you can completely remove one battery for maintenance if needed and leave the other one working.I will have two batteries in parallel at least, but yes I was thinking 100 amp would be appropriate anyway.
It is likely to only be wired such that I'll use 1500 watts of its output at the most with what I have planned. Of course plans do have a way of expanding over time!
Do you have a suggestion on where to purchase from? I had been planning on signature solar because I've heard good things about their support.Shop around a bit... You should be able to get a 5k from the OEM for ~$600 shipped.
