Not Compatible with lithium iron batteries as supplied by Shorai.

Power Rating: 450 Watts @ 14 Volts = 32 Amps.

Increases amperage by 80% over stock BOSCH systems. Stable 14.2 Voltage production under all load conditions. Electronic voltage regulator/rectifier combination remotely mounted for increased cooling and reliability, replaces diode board rectifier. High-tech permanent magnet rotor will never overheat and short out. Brushless design eliminates worn out slip rings & brushes. Eliminates "burnt out warning light" no-charge condition of Bosch systems. Will retrofit all BMW Airhead applications 1970-1995, bolts right on and wires up simply Designed and manufactured to modern OEM specifications.

Modern charging technology updates the BMW Airhead original under-performing 20 amp (max) alternator and rectifier. The critically important higher amperage output of this system at lower engine RPMs allows lighting, heating and other accessories to be used without discharging the battery or overloading the charging system. The EnDuraLast System produces 20 amps at 2000RPM! Install it now and make it the BEST and FINAL improvement to your charging system!
