Trojan T-105 Plus 6V 225Ah Battery Pack of 4 for Golf Cart

The Trojan T-105 Plus 6V Golf Cart Battery Pack — 4×6V 225Ah is a pre-matched set of four Trojan T-105 Plus deep-cycle flooded lead-acid batteries configured in series to deliver 6V volts at 225Ah — a reliable and widely used 6V battery configuration for golf carts and light electric vehicles. Each battery is a GC2-group, 6-volt flooded wet cell built in the USA under ISO 9001:2015 certified manufacturing, providing the consistent deep-cycle performance that fleet operators and recreational users have relied on for decades.

One purchase, fully matched bank

Building a 6V lead-acid bank from individually sourced batteries risks capacity mismatches when cells come from different production runs — a common cause of uneven aging and shortened pack life. This pre-specified set of four T-105 Plus batteries eliminates that risk, delivering a consistent, balanced bank ready for series wiring in a standard 6V golf cart compartment. The flooded lead-acid chemistry is also field-serviceable: cells can be watered, specific gravity can be checked with a hydrometer, and individual batteries can be swapped out, keeping long-term maintenance costs predictable.

Who this kit is for

• 6V golf carts (EZ-GO, Club Car, Yamaha, and others): A direct replacement for the standard four-battery 6V flooded lead-acid bank found in 6V golf cars.
• Golf course and resort fleets: Fleet operators who prioritize field-serviceable, proven chemistry benefit from the T-105 Plus's documented cycle performance and straightforward electrolyte maintenance.
• Light electric utility vehicles: Personnel carriers, turf vehicles, and facility equipment rated for a 6V flooded lead-acid pack.
• Off-grid solar storage (6V bus): Systems designed around a 6V battery bus where GC2 flooded cells are the specified chemistry.
• Marine trolling motor applications: Deep-cycle setups requiring a series 6V flooded bank with high amp-hour capacity for extended run time.

How components interconnect

The four T-105 Plus batteries connect in series — positive terminal of battery 1 to negative terminal of battery 2, and so on through all four — to produce 6V at 225Ah. Buyers will need to source separately: series interconnect battery cables (sized for the expected load current), a 6V charger set to bulk 29.64V, float 27.00V, and equalize 32.40V (all at 77°F / 25°C with temperature compensation applied for colder or warmer environments), and a battery tray or hold-down hardware. Trojan's HydroLink Watering System is compatible with the T-105 Plus, simplifying the periodic el
