Xantrex 1800 watt Inverter
« on: July 21, 2022, 04:01:19 pm »
Just had a Progressive Dynamic 4655 installed that Battleborn specifically recommended for out PC 2100.  I have a question that you smart folks might help me with… at what point will my inverter voltage readout indicate a charge in the 14.3 to 14.5 range that Battleborn recommends to reveal balanced full charge?
How long might a charging cycle take to bring my batteries up to full charge using my 30 amp electrical cord on a pedestal?

On a whole different subject but not wanting to flood the forum with questions, has anyone bypassed the auto entry step to coach to a manual pullout one?  Just repairing our second stripped gear and don’t know why this is happening…..neither my wife or I are “big” people,…I’m 5’8” 148lbs and she is 5’6” 115 so….this is getting old!

Thanks to all of you in advanced

Hello Greg
 It seems you are trying to determine the state of charge of your lithium batteries. The best solution and most accurate is to use a battery monitor like the Victron BMV-712 or the or the Victron Energy Smart Shunt. Using other methods is just futile. Don't get hung up on the voltage the charger hits, they only last for a short time then drop back to 13.5-13.6 resting voltage of the battery. If Battleborn suggested the Progressive Dynamic 4655 (LI) charge converter and that's what you installed your good to go, you didn't say LI. That converter is set for 13.6V to 14.6V the other version the way I understand is set-up for lead acid and its the 4655. I use the WFCO 9855LIS. If you are unsure what version you have give PD a call they have good tech support.

The step issue is interesting, I have had my PC for 3.5 years and haven't had an issue.  I have however taken it down once and regreased everything. I know one big issue, people stepping on it while its in motion, this will strip the gears.  If you have young kids around it seems they want to stand on it while its moving, bad idea, it decreases the life expectancy.

Very Respectfully
Lance

Greg,

I also installed the same Lithium Progressive Converter that Battleborn recommended since I have Battleborn Lithium batteries.  Here is some information that maybe helpful that follows what Lance mentioned.

BOOST MODE – Indicated by green LED remaining on. The output voltage is 14.4VDC to rapidly recharge the battery up to 90% of
full charge.
NORMAL MODE – When the battery is between 50% and 90% charged, the green LED will flash once per second. When the battery
has reached 90% of full charge, the green LED will flash 2 - 3 times per second. In this mode the output voltage is 13.6VDC and the
converter is safely completing the charge of the battery.

I do have the Victron BMS and when my batteries drop below 90% and I am plugged into shore power I do see on my Victron BMS 14.4 volts.  But when the batteries are charged to 90% the Victron BMS reads 13.6.   

You placed your post under the Xantrex 1800 were you planning on replacing the inverter at some point?  At some point I do plan on changing my Xantrex 1800 with the plan to replace it with a pure sine 2000 watt.   That is a future project.

Thank you Lance and Dave…we .appreciate your knowledge.  To Lance….no jumping up and down on step….we’re not that agile anymore:)….to Dave, no plans to swap out inverter….we’re simple boondockers that don’t use a lot of electronics and the 1800 watt is more than adequate for our needs.

Would the step gears strip if there is all alignment issue? Just a thought. We've had our coach for over nine years with 5.5 of those full time. We've never had an issue with the gears. We grease it periodically. The factory recommends greasing it once a month.

My 2016 model 2552 has a Progressive Dynamics 9270 (70 amps max) which I ordered from PC in the initial build.  It has their Charge Wizard control which allows one the choice of 3 voltage levels if manual control is desired or an automatic charge profile.  I contacted Battleborn and Progressive Dynamics before converting to two 100ah Battleborn batteries.  Both companies were ok with the 9270.  I very seldom use shore power or generator but rather rely on solar panels.  I have the Victron 30 amp solar controller which has the flexibility to change the automatic charge profile.


I know you didn’t ask about solar controllers but I thought I would share the charge settings I have programmed on my solar controller.  I consulted Battleborn to get their recommended settings.  I have the full charge setting at 14.4 volts.  The batteries have a battery management system (BMS) that at full charge voltage balances each of the individual cells in the battery but it needs some time to accomplish this.  I have mine set to hold 14.4 volts for 30 minutes to allow the BMS to optimize individual cell charge level.  I think that Battleborn is good with 30 minutes per battery or in my case with two batteries one hour.  Since I am typically on extended trips I chose to shorten this as the batteries are balanced daily.  After this balancing phase I have the controller to drop to 13.2 volts.  As I recall reading somewhere this balancing function needs a minimum of 14.2 volts to perform this balancing (this should be checked with the battery manufacturer).

As a follow up to my previous post, I just confirmed with Battleborn they recommend a full charge voltage of 14.4 - 14.6 volts with an absorption (cell balancing) time of 30 minutes per 100 ah battery or in the case of two 100 ah batteries in parallel a 1 hour absorption time.  They use those settings on their MPPTs to balance the battery cells.
