Re: Broker refuses to put sea trial as purchase condition

I have bought ten sailboats, all through UK based brokers. Sea trial and Survey are perfectly normal. If you find any defect through that process you can pull out and have deposit returned. A 10%...

Re: Get radical by getting simple: a 32kWh LFP house energy system

What's the model of 12V converter please? How efficient is it? Just comparing it to Victron 48-12 converter.

The idea of going LFP to 240/120V I like. Are you going to run your cooking off...

Using a chart like the one attached, or doing my own test gives a fairly accurate soc with LFP surely.

I’m 24v but my v-max coincides with your figure but I am starting v-min at 12.6v...

I don’t think it would be good value now given your investment but we have a diesel fired hot water boiler with a heat exchanger. It works like a combo boiler now, ten minutes and we have unlimited...

re: Merged LiFeYPO4 1000Ah Winston prismatic cells and all electric galley...

Do you know the BTU of each unit? We have 5 units, but the most power is drawn by the water pump which draws about 1kw on its own.

I’m just about to fit LFP and would like to run a single aircon...

Re: Realistic non-bs comparison of lithium to lead

Re: B&G forward scan

@Frankly - thanks for taking the time to share that. It's helpful - although I did 'buy' the marketing version :)

Re: How awesome can a 750Ah Lithium + 1-2kW solar boat be?
