Motobatt MLX4U MAX-HP Battery 12V 4Ah LiFePO4.
Replacement for Motobatt MLX4U MAX-HP 12v LiFePO4 battery, with 320CCA and 4ah weighing very little.
This is one of Motobatt's smallest and lightest Pro Lithium units, aimed squarely at off-road and motocross machines where shaving weight off the bike actually matters. The onboard cell-balancing circuit keeps the cells in step during use, and the battery can take a 90% charge in around six minutes flat, useful if you're topping up between motos rather than leaving it on a trickle charger overnight.
- Motobatt MLX4U MAX-HP battery replacement
A battery that's on the way out on a race or trail bike tends to show itself as slower, more hesitant kick-over on the electric start, needing several attempts to fire, or a bike that starts fine cold but struggles to restart after stalling mid-ride when it's warm. Given how much lighter and more compact this cell is than the original, it's also worth checking it's seated securely in the battery box, since a loose fit can shake connections loose on rough terrain.
There are a few closely related Motobatt part numbers in this size range so it's worth double-checking the code printed on your old battery and the dimensions given on this page rather than assuming from the bike model alone, case dimensions and terminal spacing can differ slightly between them even though they look similar at a glance.
