Smart Padlocks

Compare smart padlocks by access method and mounting clearance. Before committing to a wholesale order, confirm the shackle dimensions and the conditions in which the padlock will be used.

Selection guide

Comparing LD911 and SP902 Smart Padlocks

Select a padlock by access method and the physical clearance around the fastening point. LD911 and SP902 both list rechargeable power and fingerprint entry, but their other access options differ.

Compare access combinations

LD911 lists fingerprint, PIN, IC card and mechanical key entry. SP902 lists fingerprint access and the Smart Life app. Confirm the supplied app configuration and who will manage access before choosing a model.

Check body and shackle clearance

Compare the body dimensions below, then measure the hasp or fastening point. Request the shackle diameter, internal opening and clearance drawing; body dimensions alone do not establish whether a padlock will fit.

Plan power and exposure

Both model pages list USB-C emergency power. Confirm the charging arrangement, expected usage and exposure conditions for the order. Do not assume that all padlocks share an outdoor or waterproof rating.
