Five independent charging circuits. The PowerTender® 5-Bank 4 Amp is the first multi-bank Battery Tender® charger to offer per-bank chemistry selection and per-bank voltage selection — each of its five banks independently configurable for Lithium or lead-acid chemistry and 6V or 12V voltage. For mixed fleets, collector garages, and dealerships maintaining multiple vehicles with different battery types and voltages simultaneously, the 5-Bank is the single infrastructure solution.\u003c\/p\u003e\u003ch3\u003ePer-Bank Chemistry and Voltage Selection — What Makes This Different\u003c\/h3\u003e\u003cp\u003eThe Battery Tender® 2-Bank and 4-Bank maintain 12V lead-acid batteries independently across multiple banks. The PowerTender® 5-Bank goes further: each bank has its own chemistry selector (lead-acid or Lithium) and its own voltage selector (6V or 12V). Bank 1 can be maintaining a 12V Lithium motorcycle battery while Bank 2 charges a 6V classic car battery and Bank 3 runs a 12V lead-acid ATV battery — all simultaneously, all at full 4 Amp output per bank, all running independent ISM cycles.\u003c\/p\u003e\u003ch3\u003eISM on Every Bank, Fully Independent\u003c\/h3\u003e\u003cp\u003eEach bank runs the complete 4-stage ISM algorithm independently at 4 Amp output and the selected voltage and chemistry:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitialization\u003c\/strong\u003e — Individual battery health check before current flows on that bank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBulk Charge\u003c\/strong\u003e — Full 4 Amp output at the selected voltage restores depleted capacity for that battery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbsorption\u003c\/strong\u003e — Current tapers independently as that battery approaches full charge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloat Maintenance\u003c\/strong\u003e — Correct maintenance protocol for lead-acid or Lithium delivered 24\/7, with the correct voltage for each bank\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCompatible per bank: 14Ah to 100Ah at 6V or 12V.
