I have read through the string of information. This is definitely not a GEL battery and should changed to Lithium. The ADD is still available until the end of March. A couple of months ago I purchased the 3kw battery but did not read properly that it is for 25 volt application that would not work for me. After a bit of a battel BW took it back and I got my money back. I now want to purchase the 10kw battery at R17 000 which I think is a bargain. What is you view?
