Simple 12V Battery Charger with Battery Indicator. This is a high-end 60 Amp MPPT solar charge controller that supports 12V 24V 36V 48V system voltage automatically identification and auto switch. The project has been developed to charge the SLA (Lead Acid Battery). The charger needed to be able to perform all the three charge-stages required for a Lead-Acid battery; Absorption-charge, Equalization-charge and Float-charge (Check at the bottom of this post for some highly recommended reading about Lead-Acid-Battery charging) The donor for my project was an old 6-12V "dump-charger". Charge control with relays Battery Charging Lead acid batteries should be kept in a charged condition. PWM technology can also recover. This design is suitable for a 50W solar panel to charge a commonly used 12V lead acid battery. Camping Solar Charger; Solar Charger for portable solar systems.
