Great video. I watched it before I purchased the same elejoy booster and just received it and was able to test it today. I'll post a video shortly comparing it to the green MPT-7210A solar mppt charger. How has it worked in your boat over the past 6 months of winter? I don't know if you kept your boat in the water and used it over the winter, but maybe you kept the solar hooked up. I plan to use mine to charge 58.8v EGO batteries while camping, so am wondering how close to the full 4.2v per cell this is safe to set. In my test today the display still showed over an amp output with the volts showing 58.8v. After I disconnected the volts were below 58v, so it might not have charged beyond 58.8v once current dropped to 0. I'm curious what you think the max safe voltage level is when using this elejoy? Thanks!
80 percent is a good end point for lithium .if you check the voltage chart for your battery to stop at that. It'll keep putting current in until the battery fully reaches that voltage . Mine eventually goes to zero current despite full sun constant voltage charging type of thing. I didn't use it over the winter ,took the batteries home and stored them . Use a normal solar charger on the 12v to keep that topped up .
Thanks for the info, I'm looking at buying the same controller and using with 400w of solar and 24v LA but later with lifepo4, how long have you been using it for, and what is the most wattage panels have you used?
i've used 300w folding pannels with it without any probs . Just be wary that it's a step up MPPT to get the best out of it there needs to be a higher voltage output to charge the batteries. My solar panels put out about 19v tops and i was using this to charge 48v batteries so worked great. depending if yours is the same this should work great for 24v LA .

how much maximum amp in 72 volt

Ps, I have emailed you.

Here is a video I just made comparing the elejoy to another solar mppt boost charger:
