Well that 12V, 7amphr SLA is a beast. I get good run time but that sucker is a lead weight on the rear rack. What do y'all think is the best location for weight distribution onto the bike. I had a flat yesterday and dealing with that,while removing the battery AND making my train on time was not fun. I see some people put it in a frame bag other on a front rack. What are the pros and cons of either system. Thanks
