I am seeking to replace the converter/charger in my 2017 Airstream FC 25 FB to accommodate the unique charging requirements of my lithium-ion batteries.
Here is what I have:
- One Parallax 5355 Power Center (stock from Airstream) which provides 50 amp Service and a 55 amp Converter/Charger. Link
- Two Stark Power Deep Cycle 12-Volt 125AH batteries. (installed) Link
- One PD9180AL 80-Amp, 12 volt
, Lithium Ion Converter/Charger (not installed yet) Link
Here is the approach I’m considering:
- Leave the stock converter/charger in place in case someone down the line wants to use non-lithium batteries. However, I would leave the breaker to the stock converter/charger turned off permanently.
- Install a 20 amp receptacle compatible with the 20 amp cord that comes on the PD9180AL. This receptacle would be powered off the AC panel with a new 20 amp breaker. This receptacle would be in the same area as the power center.
- Install the PD9180AL near the new receptacle making sure there is good ventilation for it. Run two wires from the 12VDC positive leads on the PD9180AL to the 12VDC positive lead lugs on the DC Distribution Panel. Run two wires from the 12VDC negative leads on the PD9180AL to the 12VDC negative terminal bar in the Power Center. Make sure the wire is adequately sized for 80 DC Amps.
Have I missed anything?
Should I consider a lower amperage 12 volt
Lithium Ion Converter/Charger since I’d be replacing a 55 amp one with a 80 amp one?
Any help anyone could provide would be much appreciated…
