If your golf cart shipped with a lithium pack — or you upgraded — a lot of the old lead-acid habits work against you now. Leaving it plugged in all season, parking it at a full charge for weeks, or grabbing a neighbor's charger because the plug fits are the big ones.
Fall is when those mistakes show up. Courses go cart-path-only for overseeding, holiday lights get wired on, and some carts sit in a Canyon Lake or Menifee garage until Thanksgiving. Lithium is a great pack. It just has different charging and storage rules. Here is the owner-side guide for Southern California.
Still deciding on chemistry? Start with our lithium vs lead-acid comparison and lithium battery brand comparison. This post assumes you already own lithium.
Use the OEM-approved lithium charger
A lithium pack has a battery management system (BMS) that watches cell voltage, temperature, and state of charge. On factory systems such as E-Z-GO ELiTE, the charger and the BMS communicate. E-Z-GO's owner's manuals tell you to use only the OEM-approved lithium charger for that vehicle.
Do not borrow a lead-acid charger, and do not buy a random unit online just because the connector fits. Best case, it will not charge. Worst case, you get fault codes or stress the pack. If your charger failed, test it before you replace anything, or have us match the correct lithium charger for your cart.
Plug into a dedicated wall outlet
E-Z-GO's ELiTE manuals say to plug the charger into a dedicated wall outlet — no power strip, no multi-plug adapter, and nothing else sharing that receptacle. A garage strip that also runs a fridge or shop light is a common setup around Temecula and Murrieta, and it is exactly what the manual says to avoid.
Should you leave a lithium cart plugged in?
With lead-acid, many owners left the cart on a smart charger for months. For factory lithium, E-Z-GO's guidance is different: unplug the charger once the charge cycle is complete. If you need to stop a charge early, disconnect from the wall first, then from the cart.
The upside: you can top off a lithium pack after every ride. You do not have to run it down first. Short trip around the neighborhood? Charge it. When the charger shows the cycle is done, unplug it.
If the cart will not take a charge at all, work through the owner checklist in why your golf cart won't charge before you buy another charger.
Temperature matters more than people think
E-Z-GO lists a charging ambient range of about 40°F to 110°F. The BMS adjusts the charge rate based on battery temperature, and the charger can refuse to run outside safe limits.
In the Inland Empire, heat is still the bigger fall problem. Late September and early October still hit the 90s, and a closed garage in Lake Elsinore or Winchester can run hotter than the outdoor air. Park in the shade when you can, and give the cart airflow while it charges.
On the cold side: if you take the cart to the mountains or anywhere near freezing, do not charge it cold. Let the pack warm up first. A cart that will not charge on a cold morning is often the BMS protecting the cells, not a dead battery.
Fall and winter storage: 30–50% in hot climates
This is the section most new lithium owners miss.
E-Z-GO's ELiTE owner's manuals say storage charge depends on climate:
- Hot climates: store at about 30% to 50% state of charge
- Cold climates: fully charge before storage
For Canyon Lake, Temecula, Murrieta, Menifee and most of Riverside County, treat your storage as a hot-climate case. Park the cart around half, not at 100%, and not near empty.
Then:
- Turn the key off and remove it
- Turn off all accessories (lights, stereo, aftermarket accessories)
- Check the state of charge about every 30 days
- If it has dropped below about 30%, top it back toward 50%
Do not leave the charger connected for long-term storage. E-Z-GO's manuals say not to.
Why not store near empty? If a lithium pack sits very low for weeks, the BMS can shut down to protect the cells. The cart looks completely dead. That is a recoverable hassle in most cases, but a monthly check prevents it. If a stored cart already will not wake up, our after-summer wake-up guide and snowbird wake-up guide cover the first checks — and for lithium, start by confirming the BMS is not in protective shutdown before you replace parts.
Accessories and parade lights drain parked carts
LED light bars, sound bars, and the Christmas parade lights everyone wires up in November can draw power while the cart sits, depending on how they are wired. If your pack drops between rides with the key off, accessories are the first place to look. Our Christmas parade lights guide covers load, fusing, and how not to kill the pack on parade night.
Overseeding season also means more sit time. If you are on cart-path-only or sitting through a course closure, treat that stretch like short-term storage and keep the SOC in the middle of the range. See our Canyon Lake overseeding cart guide and fall prep checklist.
Lead-acid watering does not apply
If you still have a lead-acid pack on another cart, watering and summer heat care are different jobs — start with how to water golf cart batteries. Lithium packs are sealed. Do not open them, add water, or treat them like flooded cells.
Quick fall checklist for lithium owners
- Confirm you have the OEM-approved lithium charger for your pack
- Plug into a dedicated wall outlet (no power strip)
- Top off after rides; unplug when the cycle finishes
- Avoid charging in extreme heat or near freezing
- For SoCal storage, park around 30–50% SOC and check monthly
- Kill accessory drains before long sits
- Always follow your own owner's manual — model years differ
Get a lithium pack checked before the holidays
