Update on testing of CRJ LFP batteries. They are performing extremely well. I ordered 2- 200Ah LFPs from them from China. Because this is going on a boat for a house bank of batteries, I stayed with a total of 400 Ah because that apparently is the maximum that work well together without having to install external BMS's, and, that should be plenty adequate for my purposes on my sailboat-which also has 400 W of solar panels and a wind generator and operates with 12V. Upon arrival, the BMS units did not seem to be making alot of sense per the Bluetooth information I was getting from the BMS. So, I charged both to the maximum, one with a solar panel and one with a 12V battery charger. Both batteries stopped charging at about 13.67V and indicated 210 Ah available, the BMS indicated 100% charged. I then put each on a 35 Ah load (several automotive halogen bulbs wired together). After about 4 hours, the voltage was reading 12.9V and the BMS indicated 72 Ah were left. Eventually, after several more hours the batteries were down to 10.67V and remaining Ah was zero. I can say that they performed better than expected. I was very impressed with the fact that after 4 hours of a 35 A load, the voltage was still barely under 13V. All BMS readings were double checked with an amp meter and were within reasonable tolerance for small differences in the two readings. So far, I can say the batteries are quite impressive and delivering what I had hoped. For me, since I am currently in Europe, the price was great. I suspect that with the current tariff situations between the U.S. and China, the price is higher for delivery in the U.S. But they are considerably cheaper than Battle Born, not quite as cheap as a total DIY job I suspect, but still, quite reasonable. Being a newbie at this, I am not going to open the box and take a look inside and then try to reseal, unless some problem pops up.
