Hello! So I love the products you guys produce (I ditched Kranger for yall.) but im starting to run into trouble. I own 3 Aspier CF Sub Omegas.. The first one i got I was using it and the battery slowly started to degrade, the charge was lasting less and less I thought it was a fluke and bought 2 more so i could alternate batteries. My two new ones witch ive had for about 2 months (same as the first) are now holding a charge for less and less time. On top of this all 3 are now heating up to the point if i touch the metal base on my tank it burns. I clean the connections regularly and have tried a new atomizer in the tank im not sure what to do to fix this. Any suggestions?
