A starter battery system for an air cooled engine rated at less than 50 horsepower. The system includes four lithium iron phosphate cells and a charging circuit configured to be powered by rotation of an air cooled engine. A voltage developed by the charging circuit is applied to the four lithium iron phosphate cells without battery management circuitry provided between the charging circuitry and the four lithium iron phosphate cells.An engine which includes at least one piston, a rotatable crankshaft coupled to the at least one piston, a starter motor configured to selectively initiate rotation of the crankshaft, a lithium-ion battery in electrical communication with the starter motor, the lithium-ion battery having at least one cell, and a charging system configured to be powered by motion of at least one component of the engine. The charging system is configured to continuously apply a voltage potential to the at least one cell while the engine is in a running condition.An engine including at least one piston, a rotatable crankshaft coupled to the at least one piston, a starter motor configured to selectively initiate rotation of the crankshaft, a lithium-ion battery in electrical communication with the starter motor, the lithium-ion battery having four lithium iron phosphate cells, and a charging system configured to be powered by the engine. The charging system is electrically coupled to the lithium-ion battery and configured to charge the lithium-ion battery and no battery management circuitry is provided between the charging system and the lithium-ion battery.
