Trojan T-105 36V Golf Cart Battery Pack — 6×6V 225Ah

The Trojan T-105 36V Golf Cart Battery Pack — 6×6V 225Ah is a pre-matched set of six Trojan T-105 deep-cycle flooded lead-acid batteries configured in series to deliver 36 volts at 225Ah — one of the most widely trusted 36V golf cart battery configurations available. 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.

• 6× Trojan T-105 6V Deep-Cycle Flooded Lead-Acid Batteries — GC2 group size, Low Profile Terminal (ELPT) configuration, polypropylene case

System specifications

• System voltage: 36V — six 6V batteries wired in series
• Capacity: 225Ah at 20-Hr rate; 250Ah at 100-Hr rate (both at 80°F / 27°C)
• Per-battery dimensions: 10.30 × 7.13 × 11.15 in. | 62 lbs. each; total pack approx. 372 lbs. 
• Terminal type: Low Profile Terminal (ELPT) — 5/16" bolt, 95–105 in-lb (11–12 Nm) torque
• Certifications: Made in USA, ISO 9001:2015 certified, BCI and IEC compliant

One purchase, fully matched bank

Building a 36V 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 six T-105s eliminates that risk, delivering a consistent, balanced bank ready for series wiring in a standard 36V 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

• 36V golf carts (EZ-GO, Club Car, Yamaha, and others): A direct replacement for the standard six-battery 36V flooded lead-acid bank found in most 36V golf cars.
• Golf course and resort fleets: Fleet operators who prioritize field-serviceable, proven chemistry benefit from the T-105's documented cycle performance and straightforward electrolyte maintenance.
• Light electric utility vehicles: Personnel carriers, turf vehicles, and facility equipment rated for a 36V flooded lead-acid pack.
• Off-grid solar storage (36V bus): Systems designed around a 36V battery bus where GC2 flooded cells are the specified chemistry.
• Marine trolling motor applications: Deep-cycle setups requiring a series 36V flooded bank with high amp-hour capacity for extended run time.

How components interconnect

The six T-105 batteries connect in series — positive terminal of battery 1 to negative terminal of battery 2, and so on through all six — to produce 36V at 225Ah. Buyers will need to source separately: series interconnect battery cables (sized for the expected load current), a 36V charger set to bulk 44.46V, float 40.50V, and equalize 48.60V (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, simplifying the periodic electrolyte top-off that flooded cells require. A minimum of 0.5 in. (12.7 mm) spacing between batteries is recommended for ventilation, and installation in a sealed compartment is not permitted.

Why choose the Trojan T-105 36V Golf Cart Battery Pack — 6×6V 225Ah?

The T-105 is the benchmark GC2 6V deep-cycle flooded cell for a reason: a long track record in high-cycle golf cart and utility vehicle applications, backed by Trojan's T2 Technology plate design and ISO 9001:2015 manufacturing consistency. Buyers who choose this pack through A1 SolarStore get six batteries from the same manufacturer and product line, eliminating the capacity mismatch risk that comes from mixing brands or production runs. For 36V applications where field serviceability, predictable cycle life, and a globally recognized brand name matter, the Trojan T-105 pack is the established flooded lead-acid choice.
