One 12V lithium battery with the capacity of nearly three standard 105Ah batteries: 280Ah and 3,584Wh of LiFePO4 power for an RV, trailer, van, boat or off-grid setup.
The Lion UT 3500 BT-H has a built-in heater that switches on below 32°F and off again at 41°F, so it can take a charge in cold weather. It delivers 150A continuously and 280A peak, shows its charge on five LEDs and in Lion's Bluetooth app, and can be wired in series, parallel or series-parallel up to 48V for a bigger system.

Savanna BC 45 charger
Lion's 45-amp charger for lithium iron phosphate batteries, made for Lion's own lithium batteries. Lion recommends charging its 12V lithium batteries with a LiFePO4 charger like this one, and 45A is the UT 3500's standard charge rate.
Savanna IV 2000W inverter
A 2,000W pure sine wave inverter. It turns the battery's 12V DC power into 120V AC, so you can plug in household devices and power tools in an RV, van, boat or on a job site.
Solar panels
Lion's 100W lightweight 12V folding solar panel, 8.5 lbs each, to recharge the battery from the sun. Lion links up to four of these panels for more output.
