How do you think you can install that much solar on a 35ft sailing boat and still have a viable sailing boat? 1000w is about as much as you see on most sailing yachts up to about 45ft. My 44ft sailboat has 920w. Your loads are also nothing like reality. Why do you think you will be cooking for 3...

It's all pretty academic for me. Since my cells are in a sailboat, they need to be restrained from flying around the battery box. They are 'compressed' as that allows them to be fixed in place. As a bonus, we don't get any stress at the cell terminals. My cells arrived with a data sheet that...

Daly do fail. This happened to a friends Sterling battery. The passive bms is useless. With good cells you don't need to top balance if you use a JK bms. You just let the active balancer do it for you. Not possible with a Daly

My 24v built is 100L fridge freezer with lots of insulation, uses a 45w compressor running 20 mins in the hour. Less that 0.5kWh/day. In the heat of the Caribbean

What are you using it for?

Why do people buy stuff then ask if it's OK? Wouldn't it be better to ask what to buy first?

I just connect the JK BMS and charge the battery. Monitor the cell voltages when you get up near fully charged and see how the balancer gets on. If there are any cells lagging badly behind, connect your charger to that cell. Let the balancer cut off the high cell voltages.

We are on a sailboat. It's a 24v boat. Made no sense to build 12v lithium batteries but total sense to build 24v batteries. That's what we did. 2x24v lithium gives us some redundancy. The starter motor is 24v so we have a pair of lead batteries in series for that. Having everything at 24v makes...

I think the NH00 fuses are also designed to not throw molten metal around. Same principal of an enclosed ceramic fuse surround with silica sand. A very good alternative to class T and a lot cheaper in Europe. About $10 per fuse

My NH00 fuse holder is 135mm long. 160A fuse. Like class T, the fuses and holders get bigger depending on the rating of the fuse. Since I fuse each battery and I run a 24v system 160A for each battery is plenty for me. My largest load will come via the 3kw inverter which limits me to about 125A...

How do you work that out? I have class T on one of mine. It's the larger fuse as I am fused at 225A. The NH fuse holder is shorter and more compact. I have one of these mounted on my other battery. Much prefer the NH fuse

I have two diy batteries. Just saying that no AIOs at to suit that requirement

What if your systemm is 24v. You want a 3kw 24v inverter and way more battery capacity, say 400Ah at 24v. I can't see anything that compares to DIY

Thats w That is what I use. A fraction of the cost of class T but they do the job perfectly with the same AIC capability. It just shows what a rip off Class T fuses are

My understanding is it depends what you are using it for. If you intend to run high inductive loads such as motors found on AC watermakers, a low frequency inverter will be more reliable. If you just want to run resistive loads like water heaters, then a high frequency inverter will be fine.
