Standard lead-acid chargers with automatic desulfation or high-voltage recovery modes can permanently damage the integrated BMS circuit and internal cells.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: Can this battery be mounted on its side or at an angle?\u003c\/b\u003e\u003cbr\u003eA: Yes, because it utilizes sealed lithium iron polymer cell technology with no liquid acid inside, it can be mounted in any physical position required by your airbox or custom battery cage.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e When starting a bike with a lithium battery on cold mornings, turn on your bike's main power switch or bump the starter button briefly 15 to 30 seconds before hitting a full start cycle. Drawing a tiny initial current warms up internal lithium chemistry, boosting available cranking amps to help the motor fire up right away.\u003c\/p\u003e\n\u003ch3\u003eRecommended Pairings:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz250f-yz250fx-performance-parts-and-accessories\"\u003eYamaha YZ250F \u0026amp; YZ250FX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz450f-performance-upgrades-engine-mods-and-accessories-moto-house-mx\"\u003eYamaha YZ450F Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-4-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eYamaha 4-Stroke Dirt Bike Performance Parts\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
