Aili monitors vs Juntek

For Aili monitor

Just want to know what is general feedback on using the Aili monitor, I am thinking of getting the 350A shunt with it of they don't have one higher, ideally 500A.

Is it suitable for LFP batteries?

It seems that it only calibrates the full capacity of the battery, and go from there by measuring the current flow and its direction to determine the capacity left over, am I correct ?

What about the Junteck Monitor ? Anyone using it here.

I am with one of my battery packs and I do like it. But it does have it's quirks. Capacity works like you have described as is the case with most of these meters. There are several YouTube videos that explain all of this and more.

I have been using my Overkill BMS to measure capacity of my main pack and have found it to be fairly accurate. So I have been holding off on ordering a Juntek to use with it. Both meters will work with LFP batteries and there are many on this forum using the Ali monitor and some of us using the Juntek. You might benefit from searching the forum.

I have both, and they both serve their purpose. I like to see the approximate capacity left in my batteries and also see the current and voltage. It lets me get a general idea of my SOC. I also have a Thornwave Smart Shunt (500A) that has a great APP for IOS and Android. It allows me to configure and calibrate for accurate information on my SOC and logging for up to 3 years. They all work on 12V, 24V, 36V and 48V systems up to 100A-500A depending on the shunt. The Juntek and Aili are both worth it. I personally prefer the larger Aili as it provides more information at a glance. The smaller Aili is a real space saver, small and compact, but easy to read. The Juntek is versatile, but also has a higher draw. I don't have pics of the Juntek as my RV is in winter storage. They are both a great value for the price.

@Repro , thanks for the tip!

It makes sense that you use two different methods to monitor your batteries: an always-on easy-access Aili display which unfortunately doesn't even display discharged energy (in watt-hours), and the Thornwave Smart Shunt that logs full details of battery including discharged energy on-board the unit. I'll wait for that new Thornwave display under development and hopt it's as good as their shunt (mine arrives this week). Apparently it can be hardwired or communicate bluetooth with the smart shunt.
