At 190mm this one goes in, which frees the bench and floor space you were going to lose to a battery box. Measure your own base before ordering — seat mechanisms vary between conversions.\u003c\/p\u003e\u003ch3\u003eWinter charging\u003c\/h3\u003e\u003cp\u003eRenogy quote a −20°C charge floor, so this pack keeps accepting alternator and solar input on cold mornings when a standard LiFePO4 battery would refuse.

If you are planning a 3,000W inverter, either step up a size or parallel two.
