Does anyone have experience with the Sunrich Energy lithium batteries? Time to replace my 12v lead acid trolling motor batteries and considering the jump to lithium. Sunrich appears to be a division/subsidiary of Rich Solar which has been around for a long time. Seems to check a lot of the boxes with warranty, US-based support, heater, Bluetooth and decent website. Not a lot of reviews but not sure how much faith you can put in those at times. Thank you!
