I’ve got a problem with a unballanced cell on one of my own eTowers at the moment so let’s see if FW keeps up to their warranty promises. I once also started with Chinese thingamajigs (Axpert) but soon realized limitations and decided to ditch it before it failed. There was only one option for me that would compliment my blue eyes. When I replaced my Lead acid batteries with Lithium I was a bit thrown off my game though. After much homework and budgeting I got the eTowers but now after just over 2 years I’ve got a problem with one of them. I sommer wanna kots!!
