I agree that if the load is indeed 90a, which is what it would need to be, the batteries are significantly under capacity. But 90a is an...

He didn't say the alternators don't keep up. He said the batteries lost significant capacity after an hour of being fully charged. The...

You posted this as i was typing (y) I'd be suspicious about the weights, same dimensions etc, so should weigh the same, more or less.

Bit more money than BMS Tech, but they have a "challenge us on price" thing.

Yes, if you don't fancy changing to Lithium, biggest AH would be best. I have fitted several of these and had no issues with them...

If the amperage of those items add up to about 90A everything is fine, if not, the batteries are knackered.

What power monitoring system do you have? As ever a few questions: Are they both house, do you use one ore either of them as an engine...

Hardly relevant to a couple of batteries on a large, twin engined motorboat.

Still only 36kg, still not "extremely heavy" But, at a total of 72kg, a Lithium pack at about 22kg is a decent weight saving.

Would still like further information before making any suggestions, but just wanted to pick up on this point. Let's say you were...

I also live aboard, your 130ah battery would be flat in no time at all on my boat, i've used just over 5kwh today.

OP has a pair of 105ah batteries, they weigh about 12kg, 22kg not exactly "extremely heavy".

It's a 2.0 litre Toyota D4D engine, maybe something in the car/truck manuals ?

13A ring main is 2.5mm. If the controller is fitted 1m from the batteries you can use stranded 2.5mm cable, the voltage drop will be...

Post #2 is technically correct, but it does depend on where you mount the controller, in terms of distance to the batteries. How far is...
