OptiMate Solar Duo - The smart 5 amp solar controller that safely charges lead acid AND lithium 12v batteries.
The smart charge controller automatically adjusts the charge according to the battery type and condition. Connect to the battery and the OptiMate Solar Duo Controller does the rest. OptiMate Solar charge kits are fully automatic. Mount the panel in a suitable location to receive maximum sunlight, hook up the charger/monitor to the battery and walk away. No more battery problems.
Flat batteries can be saved from as low as 4v with its unique pulse action. The OptiMate Solar range features a smart charger/monitor which provides battery status information when charging and when the battery is at rest overnight.
Battery condition is displayed every 3 seconds. Ready indication for STD, AGM and Lithium LFP batteries. Draws less than 0.5mA during monitor mode and the controller will automatically switch to charge when solar power is sufficient.

I'm on my second controller. The first gave out in recent heavy weather, where water had penetrated one end and corroded various contacts, hence the loss of star. Will tighten and seal this one a bit better with silicone... Should last another 3+years that way! Controller is very clever, and monitors/indicating charge. It would have been nice to buy a bare controller, minus cables, but at least I'll have spares for the other bikes (good excuse to buy more, obviously). Can't fault the general service from Optimate either.
