Description
Modern Lithium Power for Your 36V EZGO TXT
Replace your aging lead-acid battery bank with a modern Bolt Energy 36V 105Ah Heated Lithium Golf Cart Battery Kit built for stronger, more consistent performance and dramatically less routine maintenance.
Although designed for a 36V golf cart electrical system, the battery itself operates at a nominal 38.4 volts. Its 105Ah capacity provides 4.032kWh of stored energy, while the high-output 250A Battery Management System supports demanding golf cart applications without the voltage sag commonly associated with older lead-acid battery packs.
For EZGO TXT owners who store or charge their carts in colder climates, this heated version adds an important advantage: the battery can warm itself before charging when temperatures fall below the normal lithium charging range.
Integrated Cold-Weather Heating
Cold temperatures can prevent conventional lithium batteries from safely accepting a charge. The heated Bolt Energy battery is designed to handle that automatically.
When the charger is connected and battery temperature is below the normal charging threshold, the built-in heating system activates and begins warming the battery.
Once the battery reaches approximately 34ยฐF, the heating system shuts off and normal charging begins.
The heating system:
- Activates automatically when charging temperatures are too low
- Operates only while the charger is connected
- Automatically shuts off when proper charging temperature is reached
- Allows the battery to be charged in unheated garages, barns, sheds, and similar locations
- Can warm the battery overnight so the cart is ready for use the following day
This makes the heated Bolt Energy system an excellent choice for carts used or stored in areas that regularly experience freezing temperatures.
High-Output 250A Battery Management System
At the heart of the Bolt Energy battery is a powerful 250A Battery Management System, designed to manage cell performance, charging, discharging, temperature, and overall battery protection.
The system provides:
- 250A maximum continuous discharge current
- Up to 520A peak discharge for 30 seconds
- Individual cell monitoring and balancing
- Over-current protection
- Low-voltage protection
- Temperature monitoring
- Charging protection
- Consistent power delivery under load
For upgraded golf carts, rear-seat carts, lifted carts, or vehicles running additional accessories, the high-current BMS provides considerably more performance headroom than many entry-level lithium systems.
Bluetooth Battery Monitoring
Monitor important battery information directly from your compatible mobile device through the included Bluetooth receiver.
Bluetooth monitoring makes it easier to check battery status without relying solely on a traditional dash-mounted gauge.
The Standard kit also includes a dedicated Smart SOC State of Charge meter, giving you an easy visual reference for remaining battery capacity while driving.

Golf Cart Compatibility
Designed For
- EZGO TXT electric golf carts
- 36V electrical systems
- Lead-acid-to-lithium conversion applications
The Bolt Energy #33-103 battery itself is classified by the manufacturer as a universal 36V lithium battery system. This listing packages it specifically for customers converting a compatible 36V EZGO TXT.
Before Ordering
Verify that your cart is currently configured as a 36V system.
This battery should not be ordered as a direct replacement for:
- 48V EZGO TXT models
- 48V EZGO RXV models
- 72V systems
- Gas-powered golf carts
The battery measures approximately 11.14″ L ร 10.58″ W ร 10.67″ H, so battery-tray clearance should also be verified on heavily modified carts or carts with non-standard battery compartments.
If you are unsure which Bolt Energy kit is correct for your EZGO TXT, contact Peteโs Golf Carts before ordering.
Standard Kit Includes
- 38.4V 105Ah heated Bolt Energy LiFePO4 battery

Why Upgrade to Lithium?
No More Battery Watering
Traditional flooded lead-acid batteries require regular electrolyte inspection and watering. LiFePO4 batteries eliminate that recurring maintenance.
More Consistent Power
Lithium batteries maintain a more stable voltage throughout the discharge cycle, helping the golf cart maintain more consistent performance as battery capacity decreases.
Lower Self-Discharge
The Bolt Energy battery has a manufacturer-rated self-discharge rate of less than 3% per month, making lithium particularly convenient for carts that may sit unused between trips.
High Current Capability
With 250A continuous discharge and a 520A 30-second peak rating, this system has the current capability needed for much more than a lightly driven stock golf cart.
LiFePO4 Chemistry
Bolt Energy uses prismatic LiFePO4 lithium cells, a chemistry widely used for applications requiring a balance of safety, durability, cycle life, and consistent output.
Cold-Weather Charging Capability
Unlike the non-heated version, this battery can automatically warm itself before accepting a charge when temperatures are too low for normal lithium charging.
