The battery replaces my old lead battery in an off-grid solar system and does exactly what it's supposed to, at least in the first few weeks since I got it.
The most important argument for me was the weight: Same performance with 1/3 of the weight, great!

On-time delivery. Well packaged and received safely and without damage.

The order was delivered on time and the status was always communicated. The batteries meet my expectations.

I was surprised by the super Fast and careful delivery, each battery weighs over 20kg. I'm currently testing them and will probably buy 4 more.
You are a great shop, keep it up!!

It does what it is supposed to, has the specified performance and is cleanly processed.
And the enclosed operating instructions are in German.
I'm curious to see how it does in the long term.
So far good battery

The second batteries are already there and I'm happy with the first ones. I've measured and charged it but haven't put it into operation yet... only the future will tell I was happy with the batteries and bought another 2 plus the charge controller. Delivered quickly and reliably, but the batteries were simply left in front of the door, tracking the package didn't work so well

Top fast delivery, very good Quality, runs great.

Very well made battery, I don't know why you should buy something else.

The batteries do what they are supposed to. Unfortunately, the same cannot be said for customer service! Even after several reminder emails, I still haven't received any invoices for my purchases (battery and charger). Even when contacted via FB there is no response.
