A lithium BMS is not asking for a lead-acid equalize. That voltage profile is wrong for the cells.
The answer for a lithium pack and a lead-acid equalize mode
Use the lithium charger until it finishes on its own. Unplug a charger that will not finish and find out why.
Low-temperature protection on a Vatrer pack is not an equalize cycle. It is the BMS refusing a freezing charge.
Match chemistry and voltage every time. Lead-acid chargers stay with flooded and AGM sets. Lithium chargers stay with lithium packs. A 36-volt charger is not a 48-volt charger.
Hold that answer while you read the shop notes under it. The notes are the same rules we use on every cart. The answer above is the part that is specific to a lithium pack and a lead-acid equalize mode.
The photos that stop a wrong order
Send the make, the model, the year, and the voltage you counted. Photograph one battery label so the volts and the terminal are visible. Photograph the tray with the seat up. If the cart is a Precedent, say whether it is 2004-2008 or 2009-later. If it is a Drive, say whether it is 2007-2010 or 2011-and-later or a Drive2. If it is an RXV, say metal tray, plastic tray, or factory ELiTE.
A serial number helps when the year is in doubt. A marketplace photo of the exterior does not. We would rather wait a day for a tray photo than ship PR04 hardware to a 2012 Precedent, or a 2012 kit to a 2006.
The state-of-charge meter
A Bedrock kit includes a round state-of-charge meter. Allied sells a Comm Port meter. A lithium meter reads that pack. A lead-acid fuel gauge that was wired to a string of 8-volt batteries will not tell the truth on a single lithium battery, and it may not have a 12-volt supply until the converter is installed.
If the meter is blank after a swap, check the converter and the meter plug before you condemn the battery. If the meter shows full and the cart still sags, believe the sag and do the load check. Gauges stick. Hills do not.
How series voltage is counted
Golf cart voltage is the batteries added in series, not a sticker on the nose of the cart. Six 6-volt batteries are 36 volts. Six 8-volt batteries are 48 volts. Eight 6-volt batteries are also 48 volts. Four 12-volt deep-cycle batteries are 48 volts. A 72-volt lead string is its own layout. Count the cases and read the voltage printed on one of them before you order.
A previous owner may have changed the pack. The body will not show it. A photo of one label and a photo of the tray with the seat up is the evidence. If two batteries in the tray do not match each other, the cart is not ready for a new single battery. It is ready for a diagnosis.
The charger has to match the chemistry
A lead-acid charger and a lithium charger are not interchangeable. A Bedrock kit includes a waterproof 15-amp lithium charger. Allied commercial packages include a waterproof lithium charger and a charging harness. Use that charger. Take the lead-acid charger out of the cart. Do not leave it plugged in ‘as a spare.’
A lead-acid set keeps a lead-acid charger. An automatic charger that reaches a full charge and then stops is what you want. A charger that never terminates, or that cooks a flooded battery hot, is a charger problem, not a reason to buy a bigger battery. Match charger voltage to pack voltage. A 36-volt charger on a 48-volt pack will not finish the job. A 48-volt charger on a 36-volt pack can overcharge it.
ECO case shapes and pricing
ECO’s cart batteries come as Cube, Square, Skinny, and Thru-Hole cases so the pack fits the tray you have, not a generic rectangle. Bundles pair a battery with a charger and install parts for a named cart. Some ICON parts depend on the year. The product page is the fitment note.
The ECO listings we carry state a limited lifetime warranty. ECO sets a minimum resale price, so our price follows ECO’s pricing policy. Do not ask an article for an ECO price. Open the product.
Prices live on the product page
This site does not hide a better price in an article. The price you pay is the price on the product page when you check out. ECO prices follow ECO’s pricing policy, so we do not discount those listings off the policy. Other brands are priced on their own pages.
Do not add a ‘street price’ from memory. Kits change, and a quoted number in a blog post goes stale. If you need a fit confirmed before you pay, send the cart details. We would rather hold an order for a photo than ship the wrong bracket.
Heat, garages, and flooded water loss
A closed garage in Arizona, the Coachella Valley, or a Florida afternoon can sit far above the outside air. Flooded batteries use water faster in that heat. Check them on a schedule, after charging, with distilled water. Lithium packs and chargers also have temperature limits. Do not charge a lithium pack in a heat-soaked closed garage if the battery or the charger is too hot to touch. Let the space cool, or charge in a cooler hour.
Heat is not a voltage change. A 48-volt cart does not become a 36-volt cart because the state is hot. It does become a cart that needs its water, its ventilation, and its charger checked.
Cables and lugs
The lug has to sit flat on clean lead or on the lithium terminal the kit specifies. A rocking cable arcs and pits the post. Torque it, then try to twist it by hand. If it moves, it is not done. Replace a cable whose strands are green inside the insulation or whose lug is eaten through.
A lithium kit’s cables have to be the gauge the kit asks for. Allied packages include 4-gauge cables for that reason. Do not reuse a corroded 6-volt jumper as the main lead on a 105Ah lithium pack. Hold-downs matter as much as lugs. A battery that bounces will crack a post even if the electrical work was perfect.

The price for a lithium pack and a lead-acid equalize mode is the price on the product page, not a number in this article. Lithium golf cart kits from every brand we sell ship free to the lower 48 by curbside truck freight. Parts, chargers and small batteries ship free on orders of $150 or more, or $14.95 below that. Interstate lead-acid batteries ship on a freight quote: we call you with the price before we charge shipping. We ship a lithium pack and a lead-acid equalize mode. We do not list a storefront address. Local delivery is only the area named on the shipping page. A city page on this site is not a statement that a driver covers that city.
