We've all done it. We bought the one we thought we wanted, and then realised we wanted the next model up!
If you've bought an SJ2 and we haven't yet shipped it to you, and you now want to upgrade that unit to an SJ4 with the larger battery, we've got your back!
Just place an order for this upgrade, and rather than ship you an SJ2, we'll ship you an SJ4 with the same package and accessories you've ordered.
If you've ordered a spare battery, make sure that you buy an upgrade for the battery as well - us this same item and order two (2) - one for the battery in the SJ4 and one for the spare battery.
Note that you can't order an SJ4 and a spare 200Wh battery - it just won't fit!
Of course, stock levels may affect how quickly we can send the larger SJ4 and 400Wh batteries, but if there are any issues we'll let you know straight away!
