Can A Victron Multiplus Charge A FireFly Battery?

Question:

I have a (single), new bank of five G31 firefly batteries aboard a Valiant 39. Will my Victron Energy, Multiplus 12/3000/120 charger provide enough amperage to properly maintain my FireFly battery bank? Or, do I need to divide my single bank into two banks? I am having dificulty finding answers to this question. Thank you, in advance for your input. - Mark

Answer:

Firefly batteries need at least 20% of capacity as a charge rate. In other words, 20% of 5 Gr31 Firefly batteries wired in parallel (5 X 116 = 580), is 116 amps. Therefore your battery charger of 120 amps is sufficient. - Jeff
