The SOK SK12V206H is a 12.8 V, 206 Ah lithium iron phosphate battery storing 2,636.8 Wh in a black-painted metal case of 11.9 x 7.9 x 11.1 in. SOK's spec sheet gives it 50.04 lb, IP50, M8 terminals torqued to 80-100 in-lb, 150 A continuous discharge and 170 A for 4 seconds.
The product page instead prints 48 lb, 170 A continuous and 200 A for 3 seconds. It charges at 40 A recommended and 70 A maximum, at 14.4 to 14.6 V. A heater pad switches on below 32 °F when a charger is connected and supplying enough current, and switches off at 41 °F, when cell charging resumes.
Bluetooth reports to the ABC-BMS phone app, and SOK notes that the state of charge needs two full cycles to calibrate. Up to four connect in series, with a voltage balancer, and up to ten in parallel. The lid detaches, and the BMS and cells are replaceable.
SOK's page prints a 3000-8000 cycle life and a 7-year warranty. The SK12V206PH, the same capacity with a heater in a sealed plastic marine case, sells for $750.00 and lists charging from 32 to 113 °F.
