Lithium LiFePO4 Tykool Motorcycle Battery, 12V 18Ah, 800CCA, Built in BMS from Amazon. Cost $200. In my 2021 BMW First Edition. Same size 4.9D x 6.53W x 6.9H. 900amps starting power, 4000 charging cycles. 10 times more starts, 5 times longer life. Weights only 7.2 lbs and has 18amps cold cranking amps. And can be recharged in a few minutes. I always noticed my original AGM battery always struggled a bit to crank the big 1800 cc engine. Now it is like day and night...I don't even hear the starter! I don't ride in very cold weather....only 40 degrees or more, so not a problem. Just thought I would throw this into the mix!
