TecMate O15 OptiMate 14" Y- Splitter
Connect this O15 Y splitter to your existing FUSED SAE std pigtail or your existing O1 and create two connection points. The removable weatherproof rubber sealing shrouds protects the connector against ingress of liquid and dirt. Remove and place the rubber shrouds in positions that suit your application. Length: 0.30m / 12" . WARNING: Do not use this standard Y-splitter to charge two batteries in parallel. Without a fuse between the batteries you could create a very dangerous condition (battery can explode / cable can melt) if the two batteries are accidentally  connected in reverse to each other OR one battery is discharged and the other is charged.
