  • Best voltage regulators? I need a solid 24v output (and only 15 amps)

    Trying to run a 3D printer off of batteries, I currently have them in 12v configuration but will be switching to series for 24v. I can’t find specs for the voltage on the 3D printer I have to see if it would be okay with peak charging voltage for LiFe so I’m looking for a steady 24v output...
  • Voltage drops and resets after a few seconds—stuck in safety mode?

    Hello! A little over a year ago I bought two renogy 100AH batteries since I needed something ASAP for work and Battleborn would have taken too long. In retrospect I wish I would have risked it for the Battleborn. I recently disconnected my battery system to insulate the Renogy batteries and...
  • Circuit breaker in engine bay?

    So I'm following the 400w w/alternator blueprint (without solar) and I was thinking about putting the circuit breaker between the starter battery and DC to DC charger before the firewall. That way it isolates the wire downstream leading into the vehicle. But then I'd have no easy off switch...
  • Flat mount panel vs tilt mount in winter

    So I finally decided to dive into solar this summer now that my power uses are so high (65L fridge/freezer, tons of camera/drone batteries, pressure cooker, 3D printer) and a 100W panel kept up with the 12v fridge uses while I was gone on extended work trips. I decided to put my 2 200 amp 12v...
  • Parallel DC chargers not working

    Hello! I’m looking to charge my 400 AH battery bank with a second charger while driving. Currently I use a 50 amp renogy DC to DC charger/MPPT. I’ve upgraded from a 150 to 270 amp alternator to increase the alternator charging (I have high load stuff like 3D printer, pressure cooker, tons of...
  • 12 to 24v dc to dc charger options?

    What's the highest output options for a 12 to 24v dc to dc converter with a charge profile? I'm in the process of figuring out a setup for an 11S 24v LTO system. I was hoping to take advantage of the faster charge times and use a bigger DC to DC converter (currently use a 50 amp one with my old...
  • 400w w/ alternator blueprint question

    Hello! So I’m just about to finish up my first system and I was stumbling over the orientation of my circuit breakers vs what the blueprint shows and where I should add additions fuses, etc. the instructions say have the nat side of the CB facing the battery and the load on the other side, but...
