Interesting. The charger has no controls at all so the only options are removing the positive or negative first, or unplug the charger before removing either lead.
It’s this charger….

Right now the batteries are disconnected from everything, and each other. The BMS app and AC charger (if I put that one one) both say each one is fully charged at 14.4 volts. But the multimeter says 7.8 on one and 9.8 on the other. According to the multimeter they're both very low on charge. Is...
The app says this pack is at 14.3, this bench charger stopped charging because it thinks the battery is at 14.3, but the multimeter says it's at 9.8. The multimeter seems to be right because the batteries would power anything. What do I need to do?
This only seems to happen when I fully charge up to 14.5v with a 20A LFP charger (Renogy). The charger’s light turns green when the batteries are full, the battery monitor says 100%, the charge controller’s display it on like it always is… then I disconnect the charger and everything turns off...
Thank you for helping. I’m sorry but can you please tell me more specifically which settings you’re suggesting for level 2 and 3? I see trigger and delay for level 3, which is over and which is under?
I'm new here and building a new system for a new truck camper. On my current setup I've been using 400 watts of PV with a GoalZero Yeti 1000 for a few years now, which has been great, but will be building a new system for the new truck camper. Here's where I am right now on components, listed...
My mistake, it’s two sets of four cells… 8 cells total. I was considering the Growatt 12v all-in-one but am concerned about the loud fan noise those make. The reason I went with a 3000w inverter is that the advice from a couple vendors is if the components are oversized then they won’t get as...
Renogy does a comparison between their 2000W and 3000W inverters and their advice is to go with the 3000W. If a 2000W inverter has an ordinary limit of 1600W I could easily exceed that running a couple things at a time. Renogy says, "To minimize inverter damage, only load up to 1,600W if it is...
I have 560aH (280 x2) of LifePo4 for batteries and a Renegy 500 amp battery monitor. I’ve just hooked up my system for the first time and ran the batteries down just below 10%. They’re charging back up again now, supposedly. I have a few BMS apps and they all show the same information; that the...
When that 50A DC/DC charger is used as a DC/DC charger only it is 50A. When the DC/DC charger and MPPT solar charge controller are both used at the same time it becomes a 25A DC/DC charger and 25A MPPT CC.
It's brutal, but true.
This has happened a few times now. Suddenly, my system is off and there’s no power coming out of the batteries even though they’re fully charged. I look at a BMS app and the discharge toggle is in the off position. It turns off all by itself. Why is this happening. I’m mostly using the Overkill...
Hi, I'm looking for some help. I've searched and tried to find this problem along with some answers but can't find anything about my current issue. I just built my first system for a truck camper. Everything was going great until this morning. I have two packs of 12v 280aH Eve cells in parallel...
