I bought one of these last summer and I like it . . . except that the battery monitor is not always accurate in that it doesn't recognize small amounts of draw in my campter, like the LP detector and such. It sometimes shows 0W draw when I know I have a light on or something. I charged it to 100% six days ago and it is still showing 99% charge when I know there's no way that's right. I don't know if there's a way to calibrate the BMS. I bought this particular battery so I wouldn't have to buy a shunt, but now I feel like I need to get a separate shunt anyway so I have a more accurate reading of the actual battery level.
The screen is pretty cool. I have been thinking about adding a battery to my solar fan. The fan I picked is not the best one for it as it require more start up amps than the panel can produce. I need a lower wattage fan for sure. Yet been thinking about adding a battery to it and a cheap charge controller.
@@SmitHVAC. I have a basic 100 watt panel out front of my house and a wire that runs up to the master bedroom to a switch and then to a radiator fan that is 80 watts. I bought one of those swivel tv mounts and have it installed on it. The 80w fan is just too much for the panel to spin it up in lower light conditions. If the switch is off and its super sunny I can switch it on and it will spin up and blow. If you leave the switch on all the time it wont spin any more. There is just not enough start up current to allow the fan to spin up on its own. Though in low light conditions you can touch the fan and it will spin up all the time. I have been looking at some 20 and 30 watt DC fans and even though about hooking up a cheap brushed AC fan and see how it works. Most AC stuff will run off DC.
I like when you do reviews of different batteries. Helps us more then you know when looking to build a back up source.
Very cool battery and video.
Would be nice to do a 0,2C discharge testing for capacity purposes only.

For the most part mine seems accurate, I have noticed the same thing with very light loads though

I like it, so far working good I've been using it every day. Is your fan an attic fan or just a fan in your house?

the app just ran an update on the battery and now i have lost communication with the battery ...so no i cant see the bms information.
Try contacting them
Try to update the app, i can connect with battery now .
Can you series these? I looked at there web site and i did see a series/parallel but no further information. Im trying to design a 24v system.
Yes, I had to double check the manual and it says you can
@@SmitHVAC. Awsome. Thank you very much. Looking into these as I am learning batteries are the most expensive part of a budget system.
@@tbboardhed2 they are certainly the most expensive part. I like this Temgot battery a lot, the screen is very handy and nice quality
All LiFePo4 batteries should have had this years ago and the industry has been slow to respond. I ruined a 200 AH battery by overcharging.
It's a very nice feature to have!
