The Pacemaker charger will work with all Full Spectrum Power battery systems as well as most other 12v lithium lightweight batteries.
Pacemaker is fully automatic, ensuring that your lightweight battery is always properly charged. LED indicator lights alert you to the state of charge of your system at a glance.
Works great. Seems to be a super slow trickle charger and took several hours to show a green light. Affordable and does the job.
This charger came with a separate pigtail lead that I have no idea what it is for. No paperwork, no instructions.
