The Vatrer 12V 100Ah Heated (store SKU D-12V-100AH-Black-H, spec label "LiFePO4 Battery 12.8V 100Ah") is a 12.8 V, 100 Ah LiFePO4 battery with a built-in heater, storing 1,280 Wh.
Its manual and product page rate the BMS at 100 A continuous charge and discharge, with a 1,280 W maximum load and 20 A (0.2C) recommended charging at 14.2 to 14.6 V. Below 32°F, charging input runs the heating film instead of charging the cells, and above 41°F heating stops and charging begins.
Vatrer's Amazon listing says the heater runs only with more than 10 A of charge current. It charges from -4 to 122°F, discharges from -4 to 140°F and has an IP65 case with M8 terminals. The manual gives 332 x 175 x 219 mm (13.07 x 6.89 x 8.62 in) and 24.2 lb (11 kg); the product page gives 329 x 172 x 214 mm.
Bluetooth links it to the Vatrer app. It connects four in series; the page allows up to ten in parallel and the manual no more than four, with 4P4S (20.48 kWh) the largest bank given. Vatrer's Amazon listing says it cannot be wired in series or parallel with the unheated 12V 100Ah.
