they sellthese on amazon for great prices IMHO

I have a 4600 one that does its job, im barely getting back into this with the stuff ive acquired i think 2020 will be a time to focus etc.

I would like to get a race battery however the stories I hear about these batteries and where they come from just makes me wonder if its worth 2 or 3x as much for ONE battery that is said to have a 1 year shelf life expectancy or less. Trying to find out who else is usings these brand batteries for what application and how you like em?
