Note: This thread is about the DT24P not the DL24P (with the large fan)
I'm about to start building my second hybrid solar system (sold my home and building a new one) and one of the things which I wish I did on my previous build was to test the 280Ah LiFePO4 cells prior to putting them into production but I couldn't find a reasonable capacity tester with enough current at the time.
In my research for the next build I found an interesting bench tool which could provide the solution and was wondering if anyone has one of these or has tested it? It's a DT24P (https://www.aliexpress.com/item/400...o.store_pc_groupList.8148356.6.ae3de622iuiVmJ) from Atorch and it uses a shunt and external loads to measure and report capacity of the supply. If I put 2x 100W 0.15Ω resistors in parallel, I should be able to draw around 40-50A which would mean I could test a 280Ah cell in around 6 hours at 0.2C for around $30AUD (including resistors & relay) - not bad if it works well! It also has the ability to wire up a relay to disconnect the load when the voltage reaches a configurable low voltage mark. It certainly ticks a lot of boxes and at this price, I could buy a few of these to test many cells concurrently...
So.... has anyone on here tested one of these puppies?
