Thanks Greg. I've ordered one - and will soon discover whether the seller truly does have stock!

 

[gregcope]

I asked them. They said yes!

I asked them. They said yes!

I see that in his Ebay shop he also sells unicorn tears and dragon scales!

I asked them. They said yes!

Also ... thanks for alerting me, Greg. Much appreciated.

My 300A fuses turned up. Did your @Poey50 did you order unicorns too?

Have any of you guys that built and installed lithium on your boat contacted your insurance company? I have heard a couple of stories about insurance being refused. No idea of the truth in it but companies that were mentioned were Admiral and Pantaneus. The lithium installation was said to be professionally done.

@geem. I contacted GjW who had no issues.

I heard that Topsail cancelled someone's insurance immediately on hearing of an LFP installation. I recently changed to GJW and, since they didn't require that information, I didn't offer it. I did think I might have problems at the next survey to get a renewal so I'm reassured by Greg's comment.

this is my exchange;

Subject: Lithium Iron Phosphate Batteries - Policy YT-XXXXX
From: Greg Cope <xxxxxx>
To: insure@gjwdirect.com

Hi,

I recently filled in the online contact us form but did not hear back.

I want to confirm that my insurance is not invalidated by fitting Lithium
Iron Phosphate (LifePO4) batteries.

Please could someone advise? I am assuming not, but wanted to check.


And their reply;

Topsail are a broker who seem to generally use Admiral as underwriters for boats up to about £200k. Above that they use Global. It was an OCC boat that was refused insurance (as far as I understand it). They were given 2 weeks notice to find another insurer. Pantaneus also refused them.

fwiw, I found various sizes of T-class fuses locally in Athens (apologies, page in Greek but translate works fine)
ΑΣΦΑΛΕΙΕΣ CLASS T

apparently all in stock, will check next time I visit. Wonder if there are any protected (not IP protection, just covered up to avoid shorts) cases/mounts for them

I thought this day would never come! Class-T fuses really do exist.

Thanks again Greg.

 

[gregcope]

@Poey50 Yay!

Thanks again Greg.

cor, you even have a spare, that alone could fund a new bank if "marketed" carefully

I know! I did wonder about not having a spare fuse but that seemed a bit mad.

a small update to bring up the thread



came back from Athens yesterday where I picked a 225A T-class fuse and the BlueSea housing. Compare that with the massive NH2 class fuse, a meter for scale.
Thought the T-class would be small, nah, it's 170mm long with the housing. Not particularly easy to squeeze somewhere, but at least it's protected and not in plain view ready for a spectacular short!

If anyone is in GR, Maratsinos has them in stock (see link a few posts above). Got the last housing though
ah, forgot, 120something euro for the set.

cheers

V.

Oh thats a shame @vas i liked your original fuse choice
