In simple terms, a 5A charger will charge your battery faster. The 5 amp (A) charger allows more current to pass to charge the battery. The 2A-48V and 5A chargers are compatible with the S-series and R-series vehicles. Some older S1 models may require an adapter to fit the single-prong battery charging port. Adapters are available for purchase, please contact our Order Support Team to place your order: customercare@super73.com.

The SUPER73-Z1 is limited to our 2A-36V charger due to battery size. We strongly advise against using a higher voltage charger on the Z1 battery. This prevents damage to the battery cells and a warranty void.
