2018 Tab 400 Li Time 230AH LiFePO4 with Smart shunt upgrade

JayD

The original batteries had reached end of life and thanks to the knowledge gained from this site I chose to convert to a Li Time 230AH battery, add a Smart Shunt and upgrade the WFCO to LI model internals.


This particular Tab has factory solar and factory inverter.  Battery box cover and batteries have been removed.  The Li Time battery fits very well in the space once occupied by 2 6v lead acid.




Added plywood blocks on both end two prevent the battery from sliding around. 




While awaiting parts upgraded the inverter and DC panel to the updated model which supports LI voltage needs. First step pull out the old power supply.



Next move the DC lines from the old to the new, then transfer over the fuses maintaining the same order. 


New inverter in place and the DC distribution board has an added cable and switch with a LI position. 



Cover back on and power restored/ Also refreshed the LP detector/Carbon Monoxide detector as it had aged out. 



Smart shunt installed and temporary connected direct to the battery.



All done, final add is a disconnect to ensure there are no loads of any sort on the battery when in storage. Camper is stored indoors connected to shore power, Li Time recommends keeping the battery around 50% charged and charging every three months to maintain this level.

Boondocked a couple of days to test all the systems prior to the fall season. Very happy with the results with the factory solar several days from battery with not be an issue with a 12v fridge, fantastic fan running much of the time, Alde for hot water in the morning and evening and several hours of lights in the evening. Powered the brew cycle of a coffee pot the morning of day two with the inverter.

Hi Jay,
Thank you for posting.
After 7 years, our AGM's are giving up the ghost and I want to go to Lithium.
Your install looks exactly like what ours will need to be; would you be willing to help with some specifics on parts and such?
I am pretty handy, having installed the solar myself, but this seems a bit more complicated and I have zero experience with this.

Our trailer does not currently have an inverter, I would like to add one, so this just adds a bunch of questions for me.

Let me know if you have the time / inclination to give a hand.

Thank you,

Yours,

Mark
