Just installed electric start from a donor 2012 SB Assault into my SB Pro R. It didn't come with a battery so wondering what aftermarket battery would be decent with good CCA.
I really like the YUSSA batteries and find they outlast other brands. I also like the WPS firepower or their featherlight batteries if your looking for some super light weight in a lithium style battery. Keep in mind they don't do as well in the winter but lot guys rung htem and like they because it takes a lot of weight out. I have one that is super tiny that runs my PIDD when I am stopped. Let me know if I can quote any one of these options for you.
