    Would you consider this Chinese battery isolator / disconnect / combiner ?

    Setup: - 24v - 2 batteries (8x 280Ah) - max consumption 160A (from both batteries) Would you consider this 4 position rotary switch for your campervan? (to be used as disconnect, or battery switcher, if maintenance needs arise) I know that it's not the one in the forum documentation, but it...

    Derating fuse and wiring

    Hi all. I need some insights! I'm building a system around a 24v 5000kVA Multiplus II - but this is applicable to any situation, I guess. Instructions state to use a 400A fuse and 2x50mm2 cables (under 5 meters) to battery (LiFePo4 24v 280Ah , EVE LF280k based, with a JK 200A BMS) Spec sheet...

    Brand new EVE (Grade A) LF280k from NKON arrived (made August 2022)

    12v and 24v sharing negative bus bar

    Hi. Though I searched the forum, I was not able to find an answer for this: In a van setup, fitted with a 12v electrical system, can I have a 24v house system with chassis as common ground? (no, it will not be the only ground!) Van: Ducato / Promaster / Jumper / Relay (they are all the same -...

    Howdy. Just beggining with lithium - hence been lurking in the forum reading as much as I can - though with some previous DIY experience on solar, just for fun. Been quite a learning experience around here!
