Old thread, but in Amazon one of the reviewers had a couple interesting comments regarding the backlight control and parts - You can press key V and % at the same time to turn on/off backlight. 8M cable, ASIN: B082ZPGYHZ 5M cable, ASIN: B082ZQQCVT"

Just to clarify, Amy explained these are the older fabrication EVE cells, not the AN(?), and the "new" version described as 280AH are closer to $118. Lishen 272 are significantly less. The newer ones are "fully matched" with a global warranty, studs (if requested) and certificates. Not...

What Snoobler asked you to do is measure the voltage drop across those connections. That is how you measure active resistance. Ohms law (look it up) is E=IR....So R=E/I. If you know the current (shunt should give that), measure the voltage it tells you the resistance. Resistance can be much...

Note when you install the DC-DC converters with MPPT they draw 60-70ma sitting.....so over longer periods of time they can represent a drain. Other DC to DC converters w/o MPPT draw a lot less, if that is important. A solenoid such as a Blue Sea draws no current. So if using solar you may...

So what is the minimum draw (sitting) without input from solar? The specs say <70ma....? Am I missing something? Thx

Bahamas sounds a bit like a salt atmosphere...that would be a count against easy use of aluminum.. especially in low voltage application..watch closely for oxidation...Places like most of Aussie tend to be a bit drier and less salty...

This is a sample of test values for a shipment of EVE 280 cells. Anyone have the definition the OCV 1,2,3 and Ri measurements? Charging, discharging or relationship of OCV and Ri at different values? First blush values appear consistent, but why the 3 test points? Thx

Just to add another resource, I have used this meter for years and it works very well as a clamp on and is also true rms...

I am really curious, if the panels are disconnected, what might be the draw, as I have panels planned, but really want to operate without (in a vehicle), using this as strictly DC DC. I appreciate your input and anything further you could add!

Reading the techniques for initial top balancing using 10a cc charges and how long it takes brought me to the question - why not use an existing battery charger? I have an RV Tripp Lite MRV2012 2000w 25 or 100a Inverter/Charger. Its lead acid 3 stage charging/absorption lead acid profile is...

Buck converter is a great idea (y)

Timmy it is difficult to help without your answering the questions above--- Where did you buy them from? Did you explicitly ask for new cells? What did the listing say?

As the OP asked, prime the bare wood with 2part epoxy then 2part polyU....Two part polyurethane is incredibly durable as a topcoat...1 part is very good...His choice...Really what the paint does is protect the epoxy from UV......

Using the renogy charger inverter you should be able get a controlled charge to the batteries, but it is a rather convoluted way to charge. As stated above you need to ensure isolation when things are off....That could be done by measuring for leakage between the two units. You will be running...
