I found a drop-in LiFePO4 replacement battery for my G 310 GS for a good price. Sometimes aftermarket batteries have fitment or reliability issues but this one has been great.
LiFePO4 (Lithium Iron Phosphate) batteries are superior for powersports because they last longer and are much more resistant to vibrations and heat. This also make them safer than LiPo (Lithium Polymer) batteries.
In the video, I swap out my battery for this Grecell LiFePO4 and take it for a spin. It help up nicely, although the button always seems to say 90% charge.
I purchased the battery from Amazon for $80 and it is a direct replacement and upgrade from the stock battery. It offers significantly better reliability and shouldn’t go dead during the off-season!
Note: If you are shopping for a Lithium-based replacement for the stock battery, ensure it has a BMS (Battery Management System) like this one does!
