I just got one of these and after testing it I found the setup instructions from iTech world are wrong for ITECH120X batteries which I've got 2 in parallel, after running my batteries down to 12.6V and what should have been about 30% SOC the meter was still showing 80% SOC I found the voltage was right but the SOC was out by miles so I changed the settings at S5 Battery Profile on the instructions from off to on and that seems to have fixed the problem, I think someone at iTech needs to check it out and change the instructions to what works, maybe it's just mine but I'm pretty sure it's not, in the next couple of days I'll test it again with the new settings and from what I've seen already I expect to get better results. Merry Xmas!
Glad you've got yours working. I think they're ok for AGM or silmilar but cant go past a decent shunt type one for lithium. Cheers and happy xmas to you.
@@robbiereddog4202 I've got 2 ITECH120X batteries in parallel and my settings are F 4 and in the S settings at S5 where iTech tells you to turn it off I did that and it was up the shit as far as SOC went (voltage was spot on) so I got to thinking about the S5 setting and decided to turn it on and it seem to work a lot better after I turned it on and that's when I think it started to make some sense and was more accurate to what I thought it should have been, I only did that this morning and am recharging at the moment so when it recharges I'll give it another discharge with the S5 setting turned on and I'll let you know how it goes. Cheers
@@robbiereddog4202 I brought it down again over night and finished draining it this morning and with S5 turned on the SOC was reasonably accurate and the voltage was spot on so in my opinion iTechs instructions are wrong when they tell you to turn off S5 if you have an ITECH120X battery, mine works a hell of a lot better with it turned on, if you've still got yours give it a try. Cheers Chappy.
Not sure how that’ll work. That’s just monitoring battery voltage. It’s not monitoring current in/out via a shunt at all which is how you need to keep track of SOC with LiFePO4? Simple test I guess. Plug in your external monitor also and see if numbers agree.
Yeh doesn't have a shunt so no idea about amps in and out. Think it may talk to the internal BMS of the battery and give a reading. Will test it out with an amp meter when installed. Cheers
I have one of the meters and it shows slightly different V 13.1 vs meter 13.18v % off battery 96% my setup is somewhat hybrid 12v lead acid starting battery to a L34 yellow top battery charged by a redarc bcdc charger when full 13.1 v my Itech world battery is connect to the yellow top battery with 50amp cable and sits at the rear of my car. The plan is to run a Waeco 95 ltr fridge off the lithium. I will be testing the system next week as to it working or not: so the charge from the bc-dc charger is lead acid, As the Itech120x manual stated the redback system is doing its thing and we now have almost 100amp capacity to run the fridge ,the so far no issues at all. Charging fine.
I have a anderson plug at the rear of my car that is connected to my second battery, could I just connect this to that anderson plug and still use the plug, saving me run a wire all the way to the front of my vehicle?
How do you install it on a solar system? I have 3 100w solar panels and 2 100amp batteries. I want to hook this up to that to see my battery levels. Is there a way to connect this battery monitor to a solar system?
Dont think there is. It's only a simple battery voltage guage unfortunately. Youd need an inline guarge thats shows volts and amps coming in and out or spend a little more and get an battery shunt. I ended up ditching it and getting a victron bluetooth battery monitor. Cost more but much better product. Cheers
Itech world sent me there diagram for lithium for my set up according to them 13.1 is 95% 13.5 and up is 100% A lithium battery at 70% would be 13.0v Keep in mind 70 80 and 85% is 13.0v also. I changed from AGM so the chart has changed completely.
Nice job on set-up information. Clearer than instructions provided. Cheers

@@robbiereddog4202 thank you so much.
Seems pretty complex to me !
how is 13.2v 100% ? shouldnt that be more like 70% ??

Waste of money
