Can anyone confirm if a EarthX ETX12A can fit in a 2020 YZ450F without trimming? Many seem to be using them, but have not specifically said if trimming was needed. I know they have the slightly smaller ETZ5G (that has more CCA and costs less, but slightly fewer amp capacity and does not have the over discharge protection). ETZ5G should fit without mods. I pulled out the stock lithium and tried to measure the batterybox and the ETX12A seems very close to fitting. I pinged EarthX and they say it will NOT fit. So for those running ETX12A on Yamaha YZ450F (assuming the 2018, 2019 and 2020 all have the same battery box), what specific mods, if any, did you need to do to get it to fit? I don't know if the YZ450FX and YZ450F have the same size battery box, so unless someone knows for a fact the F and FX are the same, would prefer to hear from someone that fitted a ETX12A to an "F".
From the EarthX site:
The ETX12A has 135CCA, 220PCA; weighs 1.3 pounds; has 4Ah capacity and has the full battery management system, dimensions are 4.5” L x 2.6” W x 3.7” H, with a 2 year warranty. The cost is $169.
The ETZ5G has 140CCA, 240PCA; weighs 1.1 pounds; has 3.4Ah capacity and has the battery management system minus over discharge protection and excessive cranking protection so it will not cut off in cold weather starts with a 1 year warranty. This battery was designed for high cranking amps in the cold. dimensions are 3.54” L x 1.96” W x 3.39” H, with a 1 year warranty. The cost is $139.
