Short answer: A propane cup-holder heater puts out more heat (roughly 3,400 to 6,800 BTU in the units we list) and works on any cart, gas or electric. Some, like the Mr. Heater MH4GC, are rated for outdoor use only, a poor match for a zipped-up enclosure. An electric heater (typically 400 W) has no flame and no fumes, but it must match your cart's 36V or 48V pack and it uses battery capacity while it runs.
The right one depends on three things: how your cart is powered, whether you drive with the enclosure closed, and how much range you can spare.
Propane vs electric at a glance
| Propane (1 lb cylinder) | Electric (36V or 48V) | |
|---|---|---|
| Heat output | 3,400–6,800 BTU/hr in our listings; radiant heat you feel quickly | About 400 W in our listings; a gentler, directed warmth |
| Fits | Any cart with a suitable cup holder, gas or electric | Electric carts whose pack voltage matches the heater |
| Fuel or power | Disposable 1 lb propane cylinders | Your cart battery: about 0.4 kWh per hour at 400 W |
| Use inside a closed enclosure | Only if the manufacturer's manual allows it. Some are outdoor-only | No combustion, so no carbon monoxide |
| Main trade-off | Cylinder cost, ventilation rules, flame and hot surfaces | Less heat, and some range lost on every cold round |
Propane heaters: more heat, more rules
Most propane golf cart heaters are compact radiant units that screw onto a standard 1 lb (16.4 oz) disposable cylinder and drop into a cup holder. The Mr. Heater MH4GC owner's manual gives a useful benchmark: 4,000 BTU/hr and about 5½ hours on one 1 lb cylinder. The same manual warns that runtime can drop significantly below 20°F. Higher-rated units (6,000+ BTU) feel warmer and empty a cylinder faster.
The safety rules come from the manufacturers, and they are strict:
- Outdoor use and ventilation. The MH4GC manual states the heater is for outdoor use only and warns that its odorless carbon monoxide can kill in an enclosed space. CPSC's general advice is the same: no portable propane heater indoors or in a confined space unless it is designed for that.
- Know the symptoms. Early carbon monoxide poisoning feels like the flu: headache, dizziness, nausea. If anyone in the cart feels that way, get to fresh air at once and stop using the heater.
- Clearances. The MH4GC lists minimum clearances to combustibles of 24 in above, 18 in in front and 6 in at the sides. Keep blankets, bags and enclosure panels out of that zone.
- Cylinder handling. Attach and detach the cylinder outdoors, away from flames, with the heater cool. Disconnect it whenever the heater is not in use. Never park a cart in a garage with a cylinder still attached.
If you drive with a full enclosure closed, read your heater's manual before you buy. If it says outdoor use only, either keep panels rolled up while the heater runs or choose electric.
Electric heaters: match the voltage first
Electric cart heaters run from the main battery pack, so voltage is the fitment. A 36V heater belongs on a 36V cart and a 48V heater on a 48V cart. If you are not sure what you have, count the batteries and multiply by their voltage (six 6V batteries = 36V; six 8V or four 12V = 48V), or see our 36V vs 48V guide.
Lithium conversions need one extra check. A "48V" LiFePO4 pack is usually 16 cells at 51.2V nominal, and it reaches about 58.4V when fully charged. Confirm that the heater's stated input range covers that before you wire it in. Gas carts run a 12-volt electrical system, so 36V and 48V heaters are not for them. Propane is the usual choice on a gas cart.
What it costs you in range is simple arithmetic. A 400 W heater uses 0.4 kWh for every hour it runs. That is a current of about 11 A at 36V or 8.3 A at 48V. To estimate your pack's energy, multiply volts by amp-hours and divide by 1,000. A 51.2V, 100 Ah lithium pack holds about 5.1 kWh, so an hour of heat uses roughly 8% of it. On older lead-acid packs, watch your state of charge on the first few cold rounds.
Wire it as the heater's instructions say, with the inline fuse in place, or have a golf cart technician do it.
What fits your cart
- Cup holder size. Most heaters seat in a standard cup holder, and some include an adapter. One of our electric listings, for example, specifies a 6–9 cm cup holder. Measure yours before ordering.
- Tank support. A loose 1 lb cylinder rattles and can trip a tip-over switch. A propane heater and tank holder keeps the cylinder upright, as the MH4GC manual requires during operation.
- Where the heat points. Swivel-head electric units can be aimed at hands or feet. Radiant propane heaters need the clearances above.

A heater works best with an enclosure or windshield against the wind and a seat blanket against a cold seat. The whole set is in our cold-weather golf cart gear collection. For the off-season side, see how to winterize a golf cart.
How to choose: a quick checklist
- Gas or electric cart? Gas cart: propane. Electric cart: either type.
- Enclosure closed while driving? Choose electric, or a propane unit whose manual permits that use with the ventilation it specifies.
- Pack voltage. Match the heater to 36V or 48V, and check lithium packs against the heater's input range.
- Range to spare. Budget about 0.4 kWh per hour of electric heat.
- Cup holder and tank support. Measure the holder and add a tank holder for propane.

Frequently asked questions
Can I use a propane heater inside a golf cart enclosure?
Only if the heater manufacturer allows it, and only with the ventilation the manual specifies. Some cup-holder propane heaters, including the Mr. Heater MH4GC, are rated for outdoor use only and warn of carbon monoxide in enclosed spaces. With a closed enclosure, an electric heater avoids combustion entirely.
How long does a 1 lb propane cylinder last in a golf cart heater?
It depends on the heater's rating. The Mr. Heater MH4GC manual quotes about 5.5 hours at 4,000 BTU per hour, with shorter runtimes below 20°F. Higher-output heaters empty a cylinder faster.
Will an electric heater drain my golf cart battery?
A 400 W heater uses about 0.4 kWh per hour. On a 51.2V, 100 Ah lithium pack (about 5.1 kWh) that is roughly 8% per hour of use. On older lead-acid packs the effect on range is larger, so watch your state of charge.
Can I put a 48V heater on a 36V golf cart?
No. Electric cart heaters are built for a specific pack voltage, so match a 36V heater to a 36V cart and a 48V heater to a 48V cart. For lithium 48V packs, check that the heater's input range covers the pack's full-charge voltage.
