Just found this Black Friday deal:
$399 SOK 12v 100Ah with Bluetooth and heater:
SOK 12V100Ah LiFePO4 Battery Bluetooth & Built-in Heater designed for cold weather using! Can safely charge at temperatures down to -20°C. In Stock!

Now I have a high opinion of this seller and they also have a good reputation on this forum. But either this is an extremely good deal or there’s a catch. Maybe old stock?
Even if old stock, this is a screaming deal! It’s probably going away on Monday or when they sell out.

Edit: I found the catch, only good for 12v use, not to be used in series without an external balancer (which is a good idea no matter what batteries you put into series):
- Notice: Can only be used on 12v systems, cannot be connected for 24/36/48 volt configurations without a balance management system.
I’m not super familiar with SOK batteries, so I don’t know if this restriction is coming across all their batteries or not.
