The BLUETTI B1210 is a 12.8V 100Ah deep-cycle battery built for trolling motors, camper fridges, lighting and camping power. It packs 1280Wh into a sealed case that weighs 11kg, around a third of the lead-acid battery it replaces. Bolt terminals and an IP65 casing make it at home on a transom, in a camper locker or in a portable power box. Its LiFePO4 chemistry is rated for 6000 charge cycles at 70% capacity, so it is built to cycle every day for years.
Cold is not a problem. A built-in self-heating film switches on below 0 degrees Celsius and warms the cells to about 25 degrees Celsius, as long as a charging source is connected. Charging is quick too: the B1210 accepts charge at up to 100A. When one battery is not enough, it connects up to 4 in series and 24 in parallel, growing to a bank of 122.8kWh. The Ethernet cable in the box carries the communication link between batteries; the power cables that join the terminals are not included. If you're unsure how it fits your setup, we're happy to help before you buy. B1210 Specs:
