LiTime 12V 200Ah Xtra Mini Smart LiFePO4 Battery – Group 31 Size, Bluetooth, 200A BMS

The LiTime 12V 200Ah Xtra Mini Smart packs a full 200Ah (2560Wh) into a near-Group 31 case — about 41% smaller than a standard 12V 200Ah lithium battery and light enough for a one-person install at 44.5 lb. It's the easy upgrade for RV and van battery bays sized for a single Group 31 or a pair of lead-acids: twice the usable energy, no rebuilding the compartment. Built-in Bluetooth 5.0 lets you check state of charge, voltage, current and cycle count from the LiTime app, and a 200A BMS with low-temperature protection guards the cells in cold weather.

Good to know: This is a deep-cycle house battery — do not use it as an engine starting battery or in a golf cart. When paralleling or series-connecting, use identical batteries bought at the same time. If the BMS ever trips into protection, reactivate it with a LiFePO4 charger that has an activation function.
