What our customers say
"During my tests, the battery delivered without problem the announced capacity of 100Ah and 1280Wh - or even a little more. For me, this is clearly the best choice. Thanks to the integrated Bluetooth module, I can control it very easily from my smartphone."
"A few weeks ago, we installed the electrical system in the isolated house of my mother - completely out of network. We used 4 Power Queen batteries in 12V 200AH, as well as the MPPT regulator of the same brand. Frankly, we are very impressed by the quality of the batteries. They are light, which has facilitated installation, and so far, everything works perfectly. I am really happy to have chosen this brand: quality at the rendezvous, very reasonable price.

“I am in the process of realizing theinstallation.Je I chose it for its capacity of course but also for its dimensions compatible with the battery box that I am making under the bench seat of my camper van. (The original battery was 100Ah, that's why I have to do a bit of carpentry) The price per Ampere/hour is very interesting!”
