Okay my AWs are 1.5 years old. My AWTs are 2.5 years old. They are both 350s and the AWs are 12a and the AWTs are 10.5a. Not an issue as I build for 4 Amps, tops. They are both at 4.18 but the AW hits noticeably harder. I thought that the cdr has no difference aside from builds and suitability? I thought that the only difference the age would make would be longevity of a charge? It seems my battery knowledge isn’t as sound as I thought. Can somebody help me out?
