Works great and was a fairly easy install. It took longer to get it from the company than my Litime batteries did from Amazon. Even with my military discount it was a little more expensive than some of the other brands on Amazon, even though they appear to be identical.

Installed the 40 amp Dc to Dc with MPPT in our trailer, using 6 AIG cable from the truck engine to the rear bumper, and the same 6 gauge for the trailer wiring using the connectors provided. Hooked it up to my 2 LiTme 100 ah lithium batteries, and then connected to my solar panel input. Installed 60 amp breaker on the truck wiring, a 50 amp breaker for the wire to the batteries, and a 30 amp breaker on my solar input line. Was able to select the battery type, but noting else works. Had solar panels sending out 20 - 22 volts but nothing on the unit indicating solar coming in. The “on” light never illuminated, just the “LI” light for battery type. Checked continuity on all wires, and everything is good. Called customer support, and got no answer. Sent an email over 30 hours ago, and still no response. Made 3 more calls this evening, after 8PM EDT, to be within the posted customer support hours, and was disconnected after 1 minute of listening to music each time. A defective product from a company that you cannot contact. What a ridiculous way to do business. I thought I had chosen a better company, but will try Renogy or Victron to see if I can get a product that works. It looks like wasted money dealing with LiTime.

Need support help please... it drains my starter battery and I can't figure out why? Please help. Thanks

Użytkuję ładowarkę w zestawieniu z LiFePo4 200ah ogrzewanym. Funkcja ładowania akumulatora rozruchowego poza serwisowym sprawia, że ładowarka przy tej cenie bije konkurencje na głowę. Nie spełnia zadania przy małych alternatorach 50A.
