It's not surprising that the
lithium battery is coming from Go Power (an established Escape supplier). Their specifications show a maximum of 120 A for 30 minutes, so just one of these should handle typical loads with the optional 1500 watt inverter, but maxing out the inverter will cause excessive load on the battery...
There was no real discussion of the details of higher-capacity options. That means no explanation of why they would offer two or four of the
100 Ah model instead of one or two of the
250 Ah model from the same supplier. In the Go Power specs the larger battery is strangely rated at the same charge and discharge current as the smaller batter, which makes no sense unless they are using the same management electronics and that's the limiting factor. Dimensional data are nonsensical (they are both listed as BCI group 31 but only the smaller battery is actually Group 31 dimensions) so no definitive comparison can be made; however, according to these specs the larger battery has twice the volume and 2.2 times the mass but 2.5 times the capacity.
