Lithium Vs. More Solar
Having learned so much from members here since my initial posts in early 2018, I've been grateful that the learning curve has been relatively steady, and informative. I've truly appreciated the guidan...

The gopower 250ah really isn't that great a deal, imho.
Charge current 100a. Maximum Discharge Current 100A (continuous), 120A (30 minutes)
200A (5 seconds)
$2,359 for 250ah
Look at lifebluebattery.com
Their 300ah is $2,798 and rated for Charge Current: 120A recommended; max 150A @ 75° F
Discharge Current: 150A continuous, 200A for 30 Minutes, 300A for 3 seconds
Plus bluetooth monitoring, individual cell readings, usual bms safety features. If cold is a possible issue they have new cold weather versions.
If you're thinking of adding 100ah batteries to larger ah capacity batteries your going to run into problems. Yes, they are the same voltages but the lower capacity batteries will shutdown before the larger capacity batteries. The bms's could be setup differently protecting the cells of the different packs. Stay with the same ah capacity battery.
Thanks, sir... I noted on their website they had a version designed to charge down to -4... I couldn't find anything on the site that spoke to how this was accomplished, but assume there's some sort of a built in warmer for the battery... these are a bit more pricey, but certainly cover the risk of finding oneself in below freezing weather, eh?
