Pro-Guide PGC-21236 30 Amp 3 Bank Battery Charger

The Pro-Guide PGC-21236 is a versatile multi-chemistry on-board battery charger, supporting 12V Lead Acid/AGM/Lithium, 16V Lithium, and 36V Lithium batteries across three independent charging banks. Each 12V bank can be set to one of three charge profiles, letting boaters mix and match chemistries to fit their exact setup, whether that's a single 12V Lead Acid, AGM, or Lithium bank, a second 12V/16V Lithium bank, or a third 36V Lithium bank.

An Activation Mode supplies a short burst of voltage to wake a sleeping Lithium battery automatically, or can be held for 3 to 5 seconds to enter manual activation. The PGC line is designed to stay plugged in year-round, with an Intelligent PGC Algorithm that checks each battery's state of charge on a set schedule, so it's always ready to go for the next outing.

Built-in protection covers output over-voltage, over current, short circuit, reverse polarity, and over temperature, and the charger carries an IP68 waterproof rating for reliable use in marine environments. With over 40 years of experience behind it, Pro-Guide backs the PGC-21236 with a 2 year free and 4 year total warranty. For more compatible options, shop our on-board battery chargers.
