YTX4L-BS Battery Cross Reference
A YTX4L-BS is a sealed agm (maintenance-free). It fits 12 powersports models in our data, and a lithium drop-in is made in the same case size.
AGM is the safe like-for-like: cheapest, tolerant of standard chargers and trickle tenders, and heavier. Lithium (LiFePO4) drop-ins in the same case size cut weight by roughly 60-70%, hold voltage better, and self-discharge far slower - but they cost more and need a lithium-aware charger, not an old lead-acid trickle charger.
