Re: Empty parks with no open sites.
I don't think people should be able to shonow and keep the site unused. Perhaps a day with a requirment to make contact. There are far to many campers and too few sites to let them go empty. Also there are many that could care less if they lose the meager fees in order to keep a site available just in case. JMHO470Views0likes0CommentsRe: Upgrades to make my generator quieter
I wrapped my microlite with mineral wool insulation Of course leaving all areas where the air flows and exhaust areas. This made my generator on my class c incredibly quiet. Mineral wool does not burn until over 2000 degrees and does not mold or absorb water. Pack a little around your generator I think you would be pleasently suprised.161Views0likes0CommentsRe: generator and alternator charging at the same time
BFL, I spoke with the same fella you did probably. He also told me he would ask as of yet I have not heard back from him. To explain this is exactly what I did. I drained the ut1300 to almost empty. I hooked the converter directly to the battery with foot long 8 gauge cables. I set the voltage at 14.6 and left it on the constant voltage not 3 stage. The converter fired up and did indeed charge at about 50 amps for a short time and then cut out. I am talking after about 1 minute. I was also monitoring the voltage at the battery which was slightly lower than at the converter. So then I turned up the voltage so I was getting 14.6 at the battery. I cut out quicker. Then I turned down the voltage enough to where it would run at about 40 amps and that worked. So then after a good bit of experimenting around I decided I would mess that with second pot. I found that indeed did adjust the current up and down. Of course with the higher current it would then cut out quicker. So in the end I installed in my wfco and adjusted it where I will get just about 30 to 35 amps when the battery is drained about 20 percent. It starts to slowly drop as it tops off. I have the voltage set at 14.6. I am perfectly happy with this. Lion suggest a 45 amp charge rate but also points out it can take up to a 100 amp charge rate. The bms on LION shuts off current at 14.7 on the dot. I found this in my experimenting with the converter. When I did have the alternator in the system I watched the battery getting charge at 90 amps while running the motor, I drove for about 15 minutes and that battery was amazing just guzzling the amps. I bought this battery for the convenience and the cool factor a lot more than a need factor. If I ever need a quick charge I will just put the fuse back in and let the alternator charge it up. With just one battery (my son in law has the other one) I am not to concerned with using the alternator once in a great while. I have bought other powermax converters in the past and have been pleased. I will have the other new converter in my rig for a back up. So to sum it up I could get higher current just not the full 55 and I would have to use higher voltage which as the battery topped off it would cause the bms to shut it down and I don't want that to happen. Now you know the rest of the story. :)1.1KViews0likes0CommentsRe: generator and alternator charging at the same time
BFL13 wrote: Interesting about the 55 amper LKs I will check that out. I suspect the 30 amps instead of 55 is from being in the WFCO's location and it has long thin wires to the battery. My 55 amper does 56 amps but I use short #4 wires with it. You can parallel the two 55 ampers running off the big gen and get 110 amps that might be under 100 with voltage drop if you want to do 1C on the LFP that way. EDIT--AFAIK the converter has no high current power shut down; it is just current limited to its rated current (and a bit more). Did you mean the 120v power to the converter is shut down by a generator shut down controlled by the BMS or Victron? When I ran the converter next to the battery it definitely would cut out at higher amps. I did this several times. It would run up to 50 plus amps and cut out. When I lowered the voltage therefore less amps it quit cutting out. I could get higher amos but I am okay with 30 plus.503Views0likes0CommentsRe: generator and alternator charging at the same time

You can run multiple charging sources at the same time. IF you have li-ion batteries then you will need solutions between the alternator (not made to charge these batts) and your batts. So what’s your point? I like this forum.382Views0likes0CommentsLION ut1300 Lithium
The victron bluetooth smart shunt is awesome. I put that in there first because I would not have been able to find this info without it. :) The lion ut1300 indeed does have 105 usable amps I verified that. The lion ut1300 does charge at 100 amps. One lion ut1300 does run a coffee maker or a toaster no problem. The lion ut1300 does start my 4k onboard generator easily and well within the specs of the lion. The lion ut1300 is extremely lite and small. I bought the Costco deal 2 for 1399. I think that deal is over now but if it comes back I think it is one heck of good deal. Now I have only had this battery for a month or less but so far very very impressed.

Well thanks for all the great replies! This Lion battery has been very impressive. I put in a victron bluetooth smart shunt and have done several tests of my own. My alternator alone puts in 90 amps even when the battery is at about 70 percent. I disabled that by removing the 250 mega fuse by the chassis battery. I was concerned about over taxing the alternator. That fuse is super easy to get to so if I want to use the alternator it very easy to put it back in. I also did get that powermax lk55 online for 119.00. I adjusted it to 14.6 which is what LION recommends. If you take the cover off there is second dial and you can adjust the current. I have found that the LION can take so much current so fast the most I can get is 30 to 35 amps when set at 14.6 Two problems when you turn the voltage over 14.6 one is the over current protection shuts off the power in the pm lk55 and if you set it higher than 14.6 the LION BMS shuts it down. Now this only happens at the top of the charge but I feel better running this at 14.6 so the BMD is not always kicking in. I took the cover off the converter and modified it to fit in my wfco 8900 series. I actually bought two of the pm lk55's because the price was right. I also like the idea the converter is not running at its top limits maybe it will last longer. Thanks again!383Views0likes0Comments
