Looks interesting, great price unless shipping cost is high. I emailed the distributor in Arizona a couple questions and he expects stock in 2 weeks, warranty will be with SOK, hopefully won't have to send/receive from China.
The charge rating is 50 amps/battery so charging might be slower than Battleborns or others, but with solar or alternator charging could work out just as well.
if you watch the video of the guy doing the tests, it charged at 76 amps with no issues. 50 is the recomended charge rate but I remember reading that it would handle a 1C charge rate. charging with LFP is all about how hot the battery gets, for the most part.
If it stays cool you can crank up the charge rate, unless thee is an artifical charge limit by a BMS.
The Prismatic cells I am looking at are rated in there raw form for a 5C charge rate max, but that like I said is going to depend on internal battery heat. If you cool them you could do it but why would you want to spend that much on a charger and no plugin big enough to power it.
I do like that they are using Prismatic cells in this build and I like there box design, I wonder if they will sell bare boxes?
