Hi All Does anybody know which adaptor to get to switch over to a spin-on oil filter on a DM2? The one for a BMC 1.5 looks like it might fit and I read somewhere that they used the same housing and filter element originally. Richard

These on the Renogy website show 5kA at 32v so whilst that significantly less than the 10kA at 12v 'headline figure' it's also significantly more than the megafuse 2kA at 32v. Given the amount of amps being talked about here (and elsewhere) then surely a product with a significantly higher interrupt rating has to be at least a move in the right direction? Maybe we'll all end up requiring a fuse that has to be matched to (or exceeding) each individual system? An interesting little test if an MRBF here that I stumbled across:

I think I've watched some of his videos but I might take another look, thanks 👍 Also trying to predict what the BSS and insurers might 'require' makes one think more carefully, hence trying to get it right first time (within a reasonable budget).

Many thanks for your considered thoughts on this Nick. I think I'll go the MRBF route at the battery myself and a shielded mega to replace this current monstrosity (excuse the pun 😆).

Have a look at the spec of MRBF and T class fuses and you'll see why they're becoming a requirement in some places. It's all to do with the staggering current that a Lithium battery can supply in a fault condition, as I understand it. The thread I linked to above is a good place to start 👍 Thanks, maybe I'll post there as well as I am an (albeit new) member already. Looking back over the thread I only actually received one piece of advice on the subject that I asked about and all the rest was about peripheral information that I supplied to give a clear picture of my setup. Don't ya just love internet forums some times!

From the research I've done it seems that an MRBF is probably the minimum standard required for a LiFePo4 with a class T being preferred. These seem popular: https://www.12voltplanet.co.uk/blue-sea-systems-mrbf-terminal-fuse.html Thanks for the advice. MRBF's seem fairly easy to get hold of and most of us keep spare fuses of those that we have installed so I don't really see a problem in that respect. As you say, wiring protection. I was following advice from elsewhere but I'm always open to others opinions and I haven't finalised things yet. Is fusing to protect a battery commonly done?

Apologies, I thought it was a well known term, my mistake. 250a

Evening all I've just upgraded to a 280ah Lithium house battery (with starter battery/B2B arrangement) and I'm currently in the planning stage of rewiring the battery area to reflect that we're not in the 1980's anymore (which may or may not be a shame dependant on your memories!). I was wondering how I could improve & simplify this particular arrangement? House isolator on the right, house battery off screen to the left, inverter (2800 watts) through bulkhead to the right of the fuse. I'm considering a 300a MRBF on the lithium so what should I do here? All thoughts appreciated. Regards Richard

Ah right, thanks for the explanation. Lots of post-inst testing to do then. Less. No sharp corners and they flex. What amazes me though is that my grandson seems to have some sort of built in radar that allows him to avoid the debris field that inevitably forms around a toddler whereas my feet will actively seek out the one brick (or car) that I didn't pick up! 😤

That's odd. I swear I was reading that particular product detail from a website selling them! Ho-hum.

I'm hoping so and maybe the Adverc might help in that respect?

Yes I should probably take a look at the brushes and I'll be prepared for potentially "... odd results..." Yes I'll need to keep a close eye on things for a while if I do retain the Adverc until I've used the new setup in all the likely different operating modes. Yes or maybe an A133? I have wondered if that is the reason why the Adverc was fitted in the first place.

This sounds interesting. I'm sure I saw a B2B in the last couple of weeks that would reverse charge (house to starter) as required as well?

Bring it on! (Again)

Useful to know thanks, I hadn't considered that.
