[@stevenfrazier8939]

i built 4 of the Apexium DIY Box Kits with 200A JK Inverter BMS PB2A16S20P 2A Active Balancer + 4.3inch Touch LCD Display Bluetooth, Stackable Enclosure (M8 Terminals) $620 each. they work perfect.

Cost of the cells?

[@5nowChain5]

It would be nice if manufacturers supplied a 2p8s 24v version of these stackable kits.

Good stuff, your the man. Thanks for sharing.

[@KevinSharpe]

Looks like the Pylontech power cables would work. They dont require crimping and come in lots different lengths

[@whyme8068]

That's a great box but I have some questions. Shouldn't there be insulation between the battery terminals and the top cover to prevent a dent from causing a short? Also, shouldn't there also be room for fans to keep the cells cool?

[@jehugarcia]

2 things that other boxes include in their design. But definitely not 100% needed

Saw your older videos and noticed you lived in Tijuana. Seems to be la presa, pinos or los reyes. I live in la presa and went to school Niños héroes then secundaria #4 Flores Magon

I wonder if I can combine these with my eg4ll? This looks like fun to me..I love doing g this stuf.

[@jehugarcia]

Of course you can combine them. Eg4 is just one of these pre assembled for you.

I built a unit like that a few months ago. I found out that this box is for the older PK BMS. There is no Bluetooth with this BMS you need to have a adpter that connects to a computer. The other is the negitive and positive connectors to the box are a speical plug in rather than a standard battery connector. Docan does have the newer box with the lastest BSM with bluetooth connector. I just think $550 is to much money to spend on a box and BMS.

I like the dual terminals on the front but this is too pricey. Others with a better BMS are less by a lot.

[@somaliskinnypirate]

Please include link of 'by a lot'. I just ordered a similar one by Yiaaxg (sp?) and by the time you add slow boat shipping, it's in the mid 5's minimum.

lack of some braker, onoff in front

[@jehugarcia]

Yeah I think dc breaker is a better design

[@TheDaken]

These batteries are insanely expensive and you need at least 4 of these systems to get you through the night and that's with moderate usage and that's not even covering the cost of solar and all the additional components with installation.

[@jehugarcia]

Battery has never been cheaper than today…. I don’t think you fully grasp this topic

[@somaliskinnypirate]

15kwh x 4? Wtf are you powering? I figured about 3 of these is enough for me, my 2500sq home and a 4 ton AC......These are INSANELY cheap, particularly the batteries. I'm building one similar with 15-16kwh which will come to about $1600..just as a test and to get familiar with the nuances. What's a 13kwh Powerwall with less capacity cost these days? Bit over $10k? But they're pretty! 😂 These are cheap now since the price of Chinese Lifepo4 collapsed as a commodity with respect to Federal Reserve Notes..unlike to last particularly with tarrifs.
