The OptiMate 2 Duo is a fantastic smart charger for long term maintenance of 12v lead acid batteries and 12.8/13.2v lithium batteries.

The Duo feature automatically detects the battery chemistry type (lead/acid or Lithium LiFePO4), and adjusts the charging/maintainance program to suit. Ideal for all types of 12V lead acid and 12.8V/13.2V lithium LFP batteries. 2 Amps of charge current make it ideal for long term maintenance of larger batteries too.

It includes two interchangeable SAE connection leads, one with clamps for bench charging and the other with in-line protection fuse and eyelet terminals for permanent attachment to your bike battery, to allow easy reconnection of charger when necessary.
