      Not charging

      It might be my set up, but the battery is not charging with the 200W solar panel.

      Nice battery and great support

      The battery was received fast and works exactly how it is supposed to: powering my marine electronics.
      The size allowed me to fit the battery into a small console on the boat. Battery is very lightweight and holds charge very well when not in use.
      Questions I had regarding charging with the older charger from the other supplier were quickly addressed by customer support so now I can get the battery charged properly although quite slow. I am thinking about buying specific charger from Rocksolar for much faster charging.

      Haven’t used it yet. Sent for the charger but now we need a manual/instructions on how to use them. Chat line said he would look one out later (holiday Monday). We haven’t been able to download any info. Please can you follow upon this and send instructions on both the battery and how to use the charger. Thanks
