Important Warranty Information

Do not use power tools your when tightening the terminal bolts. Over tightening can strip the terminal and will void warranty.


Installing Allied Batteries

Start by placing the cart in tow mode and turn the key into the off position. Before removing Lead Acid Batteries we advise you take a picture of your current set up. This is helpful when reattaching the cart’s wires and battery cables.

Use hand tools only and ensure the cable rings have solid flush contact with the battery terminal. Remove Lead Acid Batteries and install Allied Lithium Batteries.

Connect cables - Start with the 1 st Positive in the series and attach the cart’s positive factory wires and the Allied State of Charge Meter (Red Wire), continue connecting the series and end with the last Negative in the series by attaching the cart’s negative factory wires and the State of Charger Meter (Red/Black Wire).


Allied State of Charge Meter (SOC)

After Installing the SOC select your carts voltage.

  • Tap “Menu”
  • Then hold “Menu” until screen blinks
  • While screen is blinking tap “Menu” until the correct Voltage appears (36V or 48V)
  • Wait until blinking stops and this setting will save.

    15 Minute Rule - For accurate readings from the Allied Lithium SOC Meter the cart must be at rest for 15 minutes. While the cart is in motion the SOC will not be accurate. We suggest installing under the seat of the golf cart and on top of a batter using adhesive Velcro.



    Best Practices to ensure the maximum life of the batteries

    Charging, Break-in, Conditioning

    Charging: Allied Batteries do not ship fully charged. We suggest plugging in the Allied Lithium Charger to fully charge the batteries. Lead acid chargers will not charge the batteries correctly and can also unbalance the series batteries.

    The Allied Lithium Charger “Amp” read out (Bottom Number) will decrease from around 15A to 0A throughout the charge. When you see 0A or the green LED, there is no more charge being put into battery and the charging is complete. Unplug charger and let batteries rest for 15 minutes. If the SOC meter then reads 100% you know you have a full charge.

    Note: When the charger is plugged in and charging the SOC will usually read 100%, this does not necessarily mean the batteries are charged. The SOC will be accurate 15 minutes after the charger is unhooked from cart.

    Initial Break-in – When you first install lithium batteries, we suggest performing balancing cycles to get the longest runtime out of the batteries. It is recommended to charge the batteries full before use, run the cart for 2-4 miles, and repeat this charge/short run cycle for 4 or 5 cycles, ending with a full charge. This will allow each battery in series to reach a full charge and balance with the other batteries in the series.

    This break-in period may be performed all at once or spread out over time, however for best performance complete the initial break-in before running longer cycles.

    Periodic Conditioning – This consists of a short run (2-4 miles), then charging the batteries full. Conditioning is similar to the initial break-in, but only a single cycle. The batteries can be deep cycled, but multiple deep cycle runs (below 30%) may mean more periodic conditioning is required for best performance.

    If you are seeing the batteries drop below 95% within an hour or 2 of a full charge this is generally due to series connected lithium batteries being out of balance. Running periodic conditioning will get the batteries back in balance.

    Note: It is best to wait 15 minutes or so between charging and discharging to allow batteries to cool and stabilize.

    Running Batteries / Cart to 0%

    It is not recommended to run the batteries to 0% often as this can unbalance series connected batteries. If the batteries do go down to 0% the cart will stop running. When this happens, the following may occur:

    Charger not engaging – If the cart/charger is not engaging then you will need to, “Disconnect the series”. To do this, disconnect one of the battery cables in the series and reconnect. This resets the internal Battery Management System (BMS) inside the batteries and will allow the charger to re-engage.

    Negative Battery Reading or 0V SOC Reading–  If the SOC reads 0V or you see a battery in the series reading a negative voltage, for example “-36V”, this is usually because the BMS is in protect mode with the switches open inside the battery. Disconnect a negative terminal in the series or if there are multiple paralleled battery banks, disconnect a negative terminal from each series bank, i.e. break the series. Wait 30 seconds to a minute to discharge BMS capacitance, this will reset the BMS. If the system does not return to normal voltages, you may need to disconnect all negative terminals in the series, wait 30 seconds to a minute, then reconnect.

    Battery not charging in Series – If you are finding that one or more batteries are reaching a full charge and the remaining batteries in the series are not, this is usually a result of batteries being out-of-balance. If the voltage on a battery drops below 11V, conditioning may not easily recover the balance. Charging each battery individually with a 12V Lithium charger, high resistance paralleling, or using an active balancer are the best options. Email us at for recommended methodology.


    Cart Specific Information

    Club Car 48V - (1995-2013) - To use the required Allied Lithium Charger, Club Cars from 95-13 must have the Onboard Computer bypassed. If the OBC is not bypassed then any non-factory charger (including the Allied Lithium Charger) will not engage and/or charge the batteries.

    Club Car 48V - (2014-Current) - Compatible with required Allied Lithium Charger (No bypass needed).

    EZGO TXT - Compatible with required Allied Lithium Charger.

    EZGO RXV - Compatible with required Allied Lithium Charger.

    Avoid discharging the RXV batteries to 0%. If this does happen the brakes can lock up and must be reset. To reset brake disconnect one of the cables in the series and then reconnect, there is reserve energy in battery that will release the brake and allow the charger to engage.

    Star Car - Compatible with required Allied Lithium Charger.

    Yamaha G14-G19 / GMAX - Compatible with required Allied Lithium Charger.

    Yamaha Drive and Drive 2 - Compatible with required Allied Lithium Charger.
