    Has anyone used the Kisae DMT1250 Abso 50A DC-DC Battery Charger with MPPT?

    I've had the Kisae 50 a couple years now and works great so far. Pretty easy to program and reasonable price. I'm nervous about smoking the small 125 amp generator when idling too long in city driving with lights on etc. so I have the fused breaker where I can turn it off while seated and it's...

    Cleaning solar panels on the road?

    Frequently on dusty roads away from a car wash usually and wondered if there is a simple solution for keeping the panel clean? I have a couple gallons of water to spare usually if needed but last time I used a bit of soap it dried on the side of the van and made a mess. Any quick and easy...

    Does a USB outlet always draw amps?

    I do have a Dometic clone (Iceco) fridge that is turned off but plugged in but like you say when I open the lid the light comes on so maybe there is a controller running in the background. Sound like you guys have me on the right track as usual appreciate the great tips.

    Does a USB outlet always draw amps?

    anything powered by a remote (fans, etc.) I do have a Maxxair fan that is controlled via remote so maybe that is adding to the draw. Other than that there is nothing else connected to the house battery. Thanks for the help I will try to track down the draw

    Does a USB outlet always draw amps?

    I have a constant drain on my house battery looks like about .7 amps on the meter gizmo. The frig is turned off but plugged in and nothing is plugged in to the dual usb outlet device (although the led is always on). Also there is a bms on the 280 lith battery. I am guessing the usb has a...

    Who has experience with (blue) aluminum cells in a mobile system?

    I have the usual Aliexpress 280ah set-up and have put it through a torture test for a while now and it's the best purchase I ever made for the camper . In combo with the Overkillsolar bms probably have under $600. invested total compared to around $2700. for the Battleborn set-up. Of course...

    Thanks you just answered my other question that is if the drifting was specific to the cheap meters or applies to all types of those shunt sensors.

    AiLi Battery Monitor "% remaining" accuracy???

    I know this is a popular meter and I really like it so far for voltage readings and amperage draw and it's tested to be accurate for that but just wondering if the "percentage remaining" part of the shunt is usually accurate? I calibrated it initially by fully charging the battery and it...

    Backing plates needed inside van roof for reinforcing solar panel mounts????

    That was my worst nightmare having a panel fly off so I ended up using the vbh tape but also ran a 1/4" nut & bolt through each one and used 8" square wood backing plates glued to the inside roof since the mounts could not be near the ribs. The 180W panel did great on the hiway at 85 mph...

    Please critique my new Kisae 1250 charger programming profile for newbie

    I would love to expound on what the rep said but being a newbie and overwhelmed talking to him using terms I was unfamiliar with anything I recall would be worthless. Except that as posted: So the higher the "L" parameter setting the the faster it goes into Re-bulk mode . If you have a...

    Newbie cell balancing and BMS behavior (OverkillSolar BMS)

    I have a good meter and used it initially to check the cells. One was a tad high so I discharged that cell a bit and then the cells were all balanced but the battery was not fully charged at that point. I checked the contacts and everything is nice and tight. I am leaving on a trip in the...
