I never deal with more than 50A draw anyway, so I still don't think it's going to be a problem. My new pack might be more of an issue as it will be moved inside the house next to the battery compartment, so I will probably need leads a foot longer. If I'm getting any, it might be a tenth of a volt. The converter is on a 6 or 8awg that's not even a foot long. I don't have voltage drop in my setup - the converter connects to a remote post that is 2' away from the batteries with a 1/0 or 2/0 cable. 4-stage just doesn't work at all - you can't/shouldn't equalize a lifepo pack ever. They have half a fix, but I'm not sure how great it is, especially if they stay 3-stage. The overall feeling on RV converter/chargers has been that they are old technology that was developed for FLA and no one had done much to adapt them well for lifepo. He also said if you set the voltage it maintains it when cycling power on it. As soon as the battery settled back down it would resume. They also said if I'm running my genset with the SCC on, the converter would shut off if it sensed high voltage from the SCC. We end up running it some for the AC if it's warm anyway. This is especially nice for running the genset to charge. With a 230A lithium pack it's not going to take long to fully charge it. Yeah, they helped me out a bit.Īs I mentioned, my intention is to roll the 2-stage settings back to 14.4 and 13.4. It seemed ideal for this application, and it also seems these days if you delay on anything you just miss out. No such luck - they're just too brand and I were talking on the subject and he suggested I wait and see what I might be able to do with the IOTA before replacing it, which made sense, but the fellas from PowerMax called back (good response) so I felt obligated to jump on one. I did call them to see if they had a promotional coupon or something, or if there was an online reseller (whom normally discounts, was the thought). I would have much rather paid $125 for it, but alas. These campers came with those Paralax converters that cook batteries. I should be able to move it here or on ebay, it works perfectly. It was a good idea at the time, and does a marvelous job for the FLA's. My plan was to open it up and see if I could identify it, remove it, clip it, whatever. I have no idea how it affects the 3-stage setting(s). They told me the manual voltage adjust does both charge and float voltage level. Linky to PowerMax if you want to order one now: Not sure who else has them, but they are currently non-existent on the I have one coming next week, will update my review here. It was mentioned that Battleborn is currently testing these and will likely offer them soon. I intend to drop a couple of tenths and run it at 14.2 and 13.2. And the voltages are adjustable, default setting is for 14.6 and 13.6. If it drops below the low set point (not sure what that is yet) then it goes back into full charge mode. This solves these issues, and gives the full charge voltage for 8 hours or until the battery reaches full charge. What was a really good profile for FLA isn't so hot for lithium. Then the absorption stage kicks in and it's rather too low to get a full charge. The problem with all the 3-stage chargers is the boost stage is too short, and in some cases the voltage is too high for your lithium pack. There's also a 100A version, and they said would likely have a 75A version later in the year. Just got off the phone with them there today, they just got an initial delivery of these units so I ordered one in the 55A size. On doing a ton of research on updating my RV charging systems for a new lifepo pack I found these. Optional 3-stage for others if you need/want that option. Newly released 2-stage converter/charger specifically for LiFePo4 batteries.
