Most charger mismatches reported by Indian buyers do not begin with the charger. They begin with a vehicle name, a dealer's description, or a battery that has already been replaced once. The dependable starting point is the label on the battery pack itself.
Read the pack label before the vehicle name
An e-rickshaw or e-scooter is usually described by its class, but the pack label decides the charger. Look for three items: nominal voltage (48V, 60V or 72V), capacity in Ah, and chemistry. A vehicle running a 60V 100Ah lead-acid pack needs a 60V lead-acid charger. The same vehicle fitted with a 60V lithium pack needs the lithium profile instead, even though the voltage class is identical.
Note that the charger output rises above nominal during the constant-voltage stage. A 60V charger reading 69V to 73V at the end of the cycle is normal, because that is how the pack reaches full charge.
Lead-acid packs: capacity sets the current
Flooded and AGM lead-acid packs are normally charged at roughly 0.1C to 0.15C of capacity. In practice this means a 40Ah pack suits a 4A to 6A charger, a 60Ah pack suits 6A to 9A, and a 100Ah pack suits 10A to 15A. Charging well above that band raises pack temperature and shortens service life; charging below it is safe but takes longer.
For e-rickshaw fleets that charge overnight, a 12A to 18A model is usually enough. Fleet operators who need packs back on the road within a shift tend to choose the 18A to 35A models instead.
Lithium packs: follow the BMS, not the vehicle class
Lithium packs are less forgiving of over-voltage and over-current. Use the charge current the pack or BMS manufacturer specifies, and confirm that the charger's constant-voltage point matches the pack's series configuration. Two 60V lithium packs built from different cell counts can require different CV values.
If the pack supplier cannot confirm the CV point, ask them to send the specification sheet before the charger ships. Replacing a charger is cheaper than replacing a pack.
What to send us for a recommendation
Send the pack label photo or the specification sheet, the connector type, the number of packs charged per day, and the destination state. With those four details we can quote a matching model and confirm whether a waterproof or digital-display version is worth the difference for your site conditions.
