You can always add a Pre-charge Resistor to your Main Battery Cutoff Switch. I used a 10-ohm 25-watt power resistor across the Main Battery Cutoff Switch through a momentary push button (6A) with a LED and 10k resistor across the power resistor to show when the Caps are charged.
Edit: Or across one of the main breakers.

Hey Will, one thing I also noticed - these SOK batteries are NOT UL listed, while the budget EG4 batteries are. That alone might be worth the extra $50 if one is in the market for these right now.

Batteries seem quite expensive in the US, here in South Africa we can get 5kWh 1C LFP batteries for $1290, with a 10 year warranty on the cells. It's got a Pace BMS in it with a 5 year warranty.

That has to be the cleanest looking interior of the battery I’ve ever seen.

[cs-xdgy]

I had a bms on one of my SOK batteries burn up. It popped some cells. Dexter sent me new parts. Ultimately I was sent a new battery. Their customer service is top notch. I vote current connected.

[anthonyrichardson]

Not there in my battery journey yet, but your suggestion of pairing one of the higher cost SOK with 5 of these new lower cost units seems like a great way to go! 😊

[GavinStoneDIY]

That is so cool. I was just looking at it on their website. I know a lot of DIY people that run their system in “open loop” that are going to love this. The lack of UL listing may concern some. But the price will be right for a lot of people.

[JamesAmbrose]

Great video. I’ve already ordered a 6kw EG4 inverter, now I just ordered 2 EG4 48v batteries. Gonna have a kickass 10kw system!

Thanks for opening it up and showing us all that room inside. I like the idea of being able to pull and replace bad cells, or even being able to replace the Also, it may not come with a pre-charge resistor, but I think there is something that can be done with a small modification. However, you have also added the other option in your video, just buy one of SOKs more expensive batteries to lead off from, and then a bunch of these. I like that idea better. I was thinking of building my own batteries, but thinking of a rack and all the batteries in cases would look a lot cleaner. Thanks for the review. Will an SOK battery fit in a EG4 rack?

[Keifsanderson]

Thanks for the video. I went standard SOK last year after watching all your vids. Had this been available, I might have gone the discount route.

[smallqwaro]

this guy has the fastest outros on youtube ever. Even the 'bye' is ultra quick.

[phlogistanjones]

THANKS WILL!
As a newby the whole "you have to attach a resistor when first charging to ameliorate the inrush current" thing is kind of daunting.
Paying a bit more when you have a lower confidence level can be appealing but GOLLY these are priced to move.

[porschmn]

Look forward to your build and as usual putting them thru the paces, thanks for your update on these cheaper battery solutions.

[rodneyhunt]

Keep the prices dropping so more people can become more self reliant!

[clothedandcompetent]

After several failures trying to buy renogy while on sale, I came to your vids to find something else. I REALLY wanted to self heating option, but oh well. Bought the budget sok with your affiliate link instead. Thanks for being THE voice of solar components.

The electrical tape is to hold the quick-connector together, so it never gets unplugged on accident.

[TheWoodHaven]

State of battery readout is only convenient if you are in front of the battery. I would rather have BT, then you can be in another room (ymmv) and still get that info.

[mendohomepower]

From what I've experienced with EG4, SOK is the way to go.

[goodcitizen]

Love the price point and the high current BMS. Thanks for the review!
