Which Blue-Smart Battery Charger Do You Recommend?

Question:

Which “Blue-Smart Battery Charger” do you recommend I use for 3 connected 4 Volt FireFly Batteries?  It looks like the IP 65 is the charger to use? Did I phrase that correctly?

Answer:

Thanks for the reach out. A firefly battery bank of (3) 4V is 450 amp-hours in battery capacity and requires at least 20% of battery capacity as a charge rate. Therefore you need a minimum of 90 amps of charging and those Blue-Smart chargers are way undersized for the task. - Jeff
