Light weight at just 21kgs and totally waterproof with built-in heat sink. Can put into parallel for increased amperage or series for increased voltage (up to 48V) BUT cannot be used as a cranking battery if two or more batteries are linked in series.  Via BT app (IOS & Android) battery can be configured for 100% deep cycle or 80% for deep cycle and 20% reserved for motor cranking, so if used as a hybrid there is no risk of not being able to start the outboard motor.  Battery dimensions: 378 x 205 x 257mm (LxWxH)

10-14.8V voltage range, 12.8V nominal voltage. Lifetime of up to 6,000 cycles. Tip: Never run lithium batteries entirely flat, topping up at 50% or higher will greatly extend the life of the battery. Backed by three (3) year warranty.
