You can find 500mm jk bms switches on ebay/ali currently... Some of the BMS`s seem to come with the short switches, and some with the nice 500mm long ones..

You used to be able to turn on the JK bms`s by providing 5v more than your pack voltage... Not sure if still the case.. Download the JK BMS app, works great.. :)

740GLE, did you ever find out what that connector is called? My on/off switch port met an untimely demise... *too short of cable* and I have good friend with rockin soldering skills that can replace the port if I can find out what the dang port is and order a replacement... :)

UPDATE: Installed a relay to power the goods directly off the battery while using the output as the trigger, problem solved. Kills my power consumption monitoring, but I`ll just have to add a smartshunt to replace it....

Thank you 420, nothing in show and tell hit on my searches, and I didnt think to look there!

Looking for some ideas, Want to mount 4 100 watt panels for starters on either of two options.. Something like the Eco-Worthy adjustable racking, or their dual axis solar tracker.. Yes, the right way is to do concrete footers etc, but I`m looking for something less permanent/movable that...

How did this turn out? Ive been using the JK B2A8S20P-H with good success. one temp sensor on the top of the battery pack and one on the bottom.

I THINK I have it figured out.. I think the POE switch I`m using is having some sort of brain fart/overload that is shutting down the load output. Currently its up and running, but I have a second one I will keep onsite if it continues to happen. With the poe switch plugged in and the...

I have the 12/24/48 model, running it as a 12v system atm.

I hooked it to the load output so I could track consumption/charging in the same app. I can't find a max recommended load for the load output in the docs but seemed like people were running much larger loads than 2a thru the load output from my reading. The bms has a low voltage disconnect so...

I`ll be up at the controller later this eve and can provide more info.. I`m wondering if theres an incompatibility between a boost converter and the mppt controller.. Thought I found a discussion on that several weeks ago somewhere, but alas, I cant figure out where I saw that... .

You are correct, this is just a proof of concept to learn so far. The problem I am trying to address is not whether this is sized correctly, but why the load output malfunctions and shuts off when the battery is no where near depleted according to the log history in the controller. The...

I`ll look at settings this weekend... Its in Northern WI. Shading is not an issue, 3P on panels.

Running a Smartsolar 100/20 on a home-made 60ah lifep04 battery bank with a JK B2A8S20P-H bms. with 3 100w solar panels. Hooked up to this is a 19.5v boost converter that is powering an Asus AC68u router and a POE switch that has 2 Dahua POE cameras attached. Total draw of this system is...

Any updated thoughts after a couple months of operation?
