Hi Solar geeks! This is a little different. I want to build an off grid system but without the solar part :) For some of you this might sound crazy. But a hifi system sounds better running on batteries, that's the best. The next best thing is to run it with AC created from batteries and that’s...

8Pcs 3.2v 100ah Lifepo4 batteries give you 2400wh and there are big - Dimensions(L*W*H):142*67*215mm = 2 dm3 = bigger 4PCS NEW 3.2V 190Ah lifepo4 batteries give you 2200wh - Dimensions(L*W*H):174*54*207mm = 1.944 dm3 = smaller So the 190ah are smaller and have double the capacity, how can that...

I am trying to choose between 12v or 24v. I need around 2400wh If I use 24v 100A then I can use smaller wires and I don't work with a very high current. 12v 200A will give me a smaller battery and a smaller sin converter. So what would you recommend?

I will make a 12V 190ah battery can I use a Daly 12V LiFePO4 BMS 4S 80A/100A Battery Protection Board? I will never draw 100A that is more than a KW Normal load is around 400w

I am building a 24V 100A battery using CALB cells and a BMS Are there a charger that can start charging at a specific DOD, IE. 40% and how would I connect it. This system are not using solar cells

Hi I am trying to find out if the fan on the MultiPlus will start if I am using 4-500w for an hour. I am interested in this model MultiPlus 24/1200/25-16 but I think all MultiPlus are using the same fan. So if you use a hairdryer or similar do the fan start?

Hi first of all I live in Denmark and don't have a great selection of batteries. Many of the batteries I found on the danish sites are cheap batteries sold for a horrific price. So if you know of a good brand I can by here in Denmark I would be glad to know. But also if there are good...

I want to know if a charger is using the BMS system on the battery? I am looking for a 230v charger that I can use for charging two 12v 100ah in parallel
