Hi Klaus,

About 9 months ago I purchased 2 x 115Ah Kings AGM batteries for my van. I wasn't sure of the quality but the price was right at $179 each. Although the warranty hasn't expired yet the batteries have so far exceeded expectations. With the everchanging battery technology I was looking for something to get me through to the next "big thing" as far as batteries are concerned, which is when I will probably change to Lithium as they will be a lot cheaper then.

Kings prices change almost daily so if you intend to purchase their products it pays to monitor their prices in the days prior to when you buy to ensure you get it at the best price. I am not saying their products are top grade, but I have purchased several items from them and so far everything has worked. Kings also tend to bundle their products when on sale and although you may not need whatever extra product the item is bundled with, it is usually cheaper to buy the bundle than the single item.

I think many people tend to put Kings in the same category as Jayco. When you sell more products, the chances are you will get more poor reviews. At least they have a physical store to return any failed items to. There are many Youtube videos about Kings products, (ignore the store based ones), so take a look if you can and decide if it is worth spending the extra money.

Here is an example of what I was alluding to.

There is a banned word in the link. But, less plates (less lead) and concrete in base of the battery.

Thank you Robert, That was good info.

I know you asked about Kings AGM batteries but in many cases people can change over to LiFePO4 batteries with nil or little extra cost.

I build my own LiFePO4 batteries but recently bought a 100Ah VoltX LiFePO4 battery and a seperate battery box and was pleasantly surprised at the quality.  A number of capacity tests drew 107Ah.

If you tell us what solar charger, mains charger or DC to DC charger you have we can tell you whether they are suitable.

You will not get better value than this.

The other alternative for anyone interested is the Wattcycle brand which have some very good reviews.

Below is a 280Ah LifePO4 that I built a few months back plus the 100Ah VoltXbeing capacity tested.  The battery box looks a little different to that being advertised.

Last year I built two 100Ah batteries but now with such quality LiFePO4 batteries available at low prices at times it isnt really worth it.

Good luck which ever way you go.

rgren 2,  far out, talk about shonky of shonkies. 

I have had a very good run out of Full River AGM batteries. I have 2 deep cycle 120ah ones in my van and run a small race battery in my little Westfield 7.
