I'm asking a bunch of questions in this discussion, sorry I just lack some basic skills in this area. I'm sure a bunch of folks have had to figure this out before - hope you kept some notes.
I am having to learn how to travel and camp with a CPAP. Need to figure out what would be a safe battery capacity to recharge via the GSA alternator on a daily basis. We'll have 110 power off and on, but it might be a week to depend on the recharging.
I'm jumping the gun a little here, I don't have the CPAP machine I'll be using, so I don't know it's power requirements, but I think we are talking scale here. The vendors of CPAP machines with battery support really don't provide any capacity specs..........but, I've read where guys are using the XP-1 below with success. The XP-1 is a lithium starting battery but let's use it as an example.
I've got a 2017 GSA that has two add-on Denali D-4 lights, total 80 watts I believe. I also run a phone and radar detector. Does anyone know the output of the 2017 GSA alternator?
If I used a battery like the Antigravity Batteries' Micro-Start XP-1, can I recharge this unit from a 30% level during say a 5 hour riding day? 12 Amp Hours x 70% = 8.4 AH
Specs on the XP-1:
Battery Capacity:12000mAh (44.4Wh)
Starting Current: 200A
Output5V-1A. 5V-2A, 12V-10A, 19V-3.5A (I assume I'd use the 12V output and 10A draw would be about 10 times what I'd expect to need.)
Input 15V-1A (Does this mean the XP-1 is limited to pulling 1 A?
I'll connect the XP-1 via SAE cables from the battery. No charger or other regulator in line.
Given the stats above, how long should it take to pull 8.4 AH into the XP-1. Anyone know the AH of the OEM GSA battery?
If you use formula to calculate answers, could you include the formula so I could recreate the logic with different specs?
