Lester Summit II Series Battery Charger Quick Reference
If you own this charger, you might find the Summit II Battery Charger Quick Reference a useful tool.
System Profiles
Charger Profiles Tab–all fields on this tab are editable
Charger ID – This field is factory-set to be blank. You can change or set it on the “System Profile” and “Dashboard” screens.
Vehicle ID – Displays the ID of the vehicle that you pair with the charger (if applicable). The Vehicle ID is factory-set to be blank. You can set or change the Vehicle ID on the “System Profile” and “Dashboard” screens.
DC Cable Gauge (AWG) – The gauge of the DC cable in American Wire Gauge (AWG). This field helps user correctly compensate for the voltage drop of the DC cable.
DC Cable Length (feet) – The length of the DC cable in feet [one direction only, not the sum of the length of both the positive (+) and negative (-) wires]. Use this field to correctly compensate for the voltage drop of the DC cable.
On Board check box – Features a \”check\” for On-Board and a \”unchecked\” box for Off-Board.
On-Board chargers are made to mount on electric vehicles/equipment. When you connect the DC output to a battery pack, a charge cycle automatically starts after you connect the plug to AC power. Remember to wait for a safe period of time to elapse after the successful completion of the previous charge cycle.
NOTE: Disconnecting the DC output from the battery pack IS NOT A REQUIREMENT to automatically start a new charge cycle.
Off-Board chargers are for shelf or portable applications. As you connect the AC input plug to live AC power, a new charge cycle automatically starts after you connect the DC output to a battery pack. Disconnecting and reconnecting AC power while the DC output remains connected to a battery pack WILL NOT automatically start a new charge cycle.
NOTE: Disconnecting the DC output from the battery pack IS NOT A REQUIREMENT to automatically start a new charge cycle.
On-board configuration- you can use it in a shelf or portable application where the DC output connector/plug connects and disconnects from the vehicle. But when configuring a charger as Off-Board, you should mount it on a vehicle with the DC output permanently connecting to the battery pack. This is because the charger will not automatically start a new charge cycle when you apply AC power to the charger.
Auto Voltage Profile – Only present on charger models that support Auto Voltage Mode. See the “Auto Voltage Mode” section below for details.
Cloud Profiles Tab
- System profiles available for download from the ChargerConnect Cloud.
- Download system profiles from the Cloud to your smart phone or tablet via the green arrow buttons.
- Blue question mark buttons provide detailed list of the system profiles.
Device Profiles Tab
- Lists of all system profiles available on your smart phone or tablet (device).
- Upload a system profile that resides on your smart phone or tablet to the connected charger via the green arrow button.
- Details of the system profiles can be found under the blue question mark buttons.
- Delete system profiles that reside on your smart phone or tablet (device) via the red trash can button.
Auto Voltage Mode
Some Summit Series II charger models support automatic multi-voltage DC charging (Auto Voltage Mode). Auto Voltage Mode provides automatic DC output voltage detection and adjustment so that battery packs of nominal 48V and 36V (650W 48V, 36V, and 48-36V models) or nominal 48V, 36V, and 24V (all 1050W models) will charge with a single charger. No configuration changes are necessary when switching between battery packs of different nominal voltages.
When the connected charger model supports Auto Voltage Mode, the “System Profile” screen will include an “Auto Profile” selection box, which provides the following three (3) options:
OFF: Single voltage mode – you MUST ensure that the nominal DC voltage of the “Active Battery Profile” for the charger matches the nominal DC voltage of the connected battery pack.
PER VOLTAGE PROFILES
- 650W 48V, 36V, and 48-36V models: You can assign different battery profiles for 48V and 36V. The charger will automatically select the proper battery profile per the battery pack that you connect. You can use this mode when the charger will be charging 48V and 36V nominal battery packs where the battery packs are of different types and/or capacities so using the “Scalable Profile” mode is not appropriate.
- All 1050W models: You can assign a battery profile for 48V, and a different battery profile for 36V and 24V. The charger automatically selects the proper battery profile contingent on the battery pack you connect. You can use this mode primarily when the charger will be charging 48V, 36V, and 24V nominal battery packs [or any combination of two (2) of these voltages] where the battery packs are of different types and/or capacities so using the “Scalable Profile” mode is not appropriate.
SCALABLE PROFILE
- 650W 48V, 36V, and 48-36V models: the nominal DC voltage of the “Active Battery Profile” will automatically scale to 48V or 36V based on the connected battery pack.
- All 1050W models: the nominal DC voltage of the “Active Battery Profile” will automatically scale to 48V, 36V, or 24V based on the connected battery pack.
NOTE: Under “Per Voltage Profiles” or “Scalable Profile” mode, if you set the “Auto Profile” selection box to “Off”, you MUST ensure that the nominal DC voltage of the “Active Battery Profile” for the charger matches the nominal DC voltage of the connected battery pack via the “Battery Profiles” screen.
When Auto Voltage Mode is active (either “Per Voltage Profiles” or “Scalable Profile”) the “Dashboard” screen shows “Auto Battery Voltage Detection” as a status percentage and the “Detected Battery Pack Voltage” (see the “Dashboard” section).
Battery Profile
Charger Profiles Tab
- Battery profiles that are available on the connected charger.
- Click green check mark to set the “Active Battery Profile”.
- Descriptions of the battery profiles (blue question mark).
- See the “Battery Profile Quick Reference” section below for info about the most common profiles.
Cloud Profiles Tab
- Profiles available for download from the ChargerConnect Cloud.
- Download profiles to smart phone or tablet via the green arrow buttons.
Device Profiles Tab
- Battery profiles available on your smart phone or tablet.
- Upload battery profiles that reside on your smart phone or tablet (device) to the connected charger via the green arrow buttons
Select a “Profile Slot Number”. Summit Series II chargers can store up to 20 battery profiles locally in slots which are numbered 0-19. You can store a profile in an empty slot or a used slot. If you select a used slot, the battery profile will overwrite the existing profile.
Please note that when you upload a battery profile to the connected charger, it automatically becomes the Active profile on the charger. Delete battery profiles that reside on your smart phone or tablet (device) via the red trash can button.

On a 48V 1996 Club car DS with US Battery 8V ( 6 pack ) the are the model VCG X2 which the manufacture suggested Charger peak Voltage should be 62V. Plus they recommend 1 equalization charge we month at 2.55 VP or 61.2V total for 2-3 hours . This seems all higher then Trojans guidelines. The US Battery Voltage at 100% full charge on 48V is 51.3V vs Trojan are 50.9V

Can you tell me what Lester or other on board charger would be best ?
John – Hands down we would recommend the new Lester Summit II Series chargers as they are the smartest ones right out the box. The list of features and benefits is quite long and the manufactures warranty is the industry best at 4 yrs. See link below…

As for your question about batteries … All battery manufacturers have their guidelines and know their product. But the main thing to understand is that lead based batteries need a curing process that just is not ideal for the manufacturer to implement. So the first 15-25 charge cycles of a lead acid batteries life will energize the plates and cure the lead. At this stage they like to get popped hard and are like a sponge when it comes to sucking up a charge. Across the board all lead acid batteries are not going to be flat at 6v, 8v or 12v when charged. They should all be above 2.08 volts per cell. This brings us back to the new Lester Summit II Golf cart Battery Chargers as they have a built in storage mode that will kick the charger back on if the batteries ever fall below that voltage.
Power On…
