⚙️ Selectable, most features
Save, test, charge & maintain

Designed with the expert in mind that wants to select the right program to charge their battery, the GOLD SERIES OptiMate 4 Quad Program is the ultimate power-sport battery saving charger for your 2-wheel adventure, touring, cruiser or performance motorcycle, or your 4-wheel ATV & Side by Side UTV, or your personal watercraft.
OptiMate 4 Quad Program offers four different charging programs, for all types and sizes of engine-start (SLI) battery used in power-sport, including 12V lead-acid (Pb – classic wet cell or sealed / VRLA AGM or GEL) and 12.8V / 13.2V lithium (LFP / LiFePO4).

Programs 1 (Pb) and 3 (LFP) work best when connecting directly to the battery, automatically activating from as low as 0.5 Volts for ‘no supervision’ save, charge, test and 24-7 maintenance of your battery. Program 3 (LFP) also include BMS reset and ‘wake up’ of a lithium (LFP) battery from zero Volts.

Programs 2 (Pb CAN-bus) and program 4 (LFP CAN-bus) are specific to BMW motorcycles (from 2004) that have the 12V socket controlled by the motorcycle’s ZFE CAN-bus system. OptiMate 4 Quad Program automatically initializes, then charges and maintains through the BMW motorcycle’s 12V socket, safely within the parameters of the BMW CAN-bus system. During long term maintenance OptiMate 4 Quad Program monitors the battery and will deliver charge as needed, to keep that battery in perfect condition. TIP: If your BMW motorcycle’s battery is dead-flat (no reaction or ignition lights when turned on) you will need program 1 or 3 to save the battery.

OptiMate 4 Quad Program include OptiMate’s best battery saving algorithm in program 1 for lead-acid (Pb) and program 3 for lithium (LFP) batteries. All save modes are vehicle safe, if OptiMate 4 QP senses sensitive vehicle electronics, it disables save mode functions; for best results disconnect the battery from the vehicle and then OptiMate 4 can use maximum saving power to bring your battery back to life. After saving it will test and indicate your battery’s state of health. Guaranteed, if OptiMate 4 cannot save your battery, no other power-sport / motorcycle charger will!

Motorcycle lithium battery charger

Motorcycle / Powersport Lithium Series

lithium corner on battery charger
🛠️ Expert
⚙️ Specific features, BMS reset
Reset, save, test, charge & maintain

Designed for automatic and easy use, but packed with intelligence to correctly reset, save, charge, test and maintain 12.8V / 13.2V Lithium LFP (LiFePO4) starter or auxiliary battery, an OptiMate Lithium SERIES battery charger is the expert choice for your high performance race, cruiser or adventure motorcycle with a Li-Ion LFP/LiFePO4 battery.

OptiMate has been an industry leader in Li-Ion (LFP / LiFePO4) starter battery knowledge since 2010, focusing on optimal battery care and longevity. Even though the Li-Ion (LFP / LiFePO4) battery works similar to lead-acid in the 12V to 14.4V range of a motorcycle’s electrical system, when the lithium battery is deeply discharged below that range, especially below 10V, it is vulnerable to damage and requires a different way of recovery compared to lead-acid. OptiMate Lithium delivers low power charge whilst actively testing to see how the battery reacts, so that it can determine if the battery can be safely recharged. If not it will immediately stop and indicate battery error, preventing the battery from overheating. If the discharged battery is healthy and reacts as expected, it will be delicately and precisely brought up to its normal voltage range before it receives full current charging again.

OptiMate Lithium series chargers feature AmpMatic current adjusting technology, low voltage pulse recovery from 0.5V,  active BMS (battery management system) reset for batteries with built-in resettable protection systems, state of health testing and temperature compensation that reduces or prevents charging in extreme cold or heat.

OptiMate 4 Quad Program FAQ

OptiMate 4 Quad Program includes four charging programs; the standard program for lead-acid batteries is supposed to be used when connecting directly to the battery, the CANbus (BMW) program for lead-acid batteries allows charging and maintaining via the DIN socket on BMW Motorcycles (models 2004 and later).

The standard program for lithium batteries is supposed to be used when connecting directly to the battery, the CANbus (BMW) program for lithium batteries allows charging and maintaining via the DIN socket on BMW Motorcycles (models 2004 and later).

Yes, the standard program has the most advanced recovery program which saves 'dead flat' sulphated batteries from as low as 0,5V.

You'll need to select Program 2 (Pb-CAN-bus) or Program 4 (LFP-CAN-bus) depending on the type of battery in your BMW motorcycle. Program 2 is for a 12V sealed lead-acid battery - your sealed battery may be marked 12V VRLA, GEL or AGM. Program 4 is for a 12.8V LFP (Li-Ion with chemistry LiFePO4) battery.

Disconnect the OptiMate 4 from the battery or vehicle. Push and release the pushbutton switch. The mode selection changes when the button is released. Continue to press and release until the desired program has been selected. If no futher selection is made for at least 3 seconds SAVE (#3), CHARGE (#4), OPTIMIZE(#5) and TEST (#6,7, 8) LEDs flash twice to confirm selection is in memory.

The standard edition is delivered with a set of battery clips (O-04), a permanent battery lead (O-01) and a handlebar hanging hook to suspend the charger from the handlebar. The Premium edition includes all the same accessories PLUS a SAE to DIN adapter (O-19) to connect directly to 12V DIN sockets on BMW and Triumph motorcycles.

Yes, IF the socket is ‘live’ (hot) when the motorcycle ignition is turned off. (TIP: Recent model Triumph Tiger 850/900 and 1200/1250 have a live socket near the instrument panel.). Select program 1 or 3 for direct-to-battery charging as the socket is directly connected to the battery.

STD, AGM and GEL 12V lead-acid & 12.8V / 13.2V lithium LFP (LiFePO4) batteries used for engine start & deep cycle applications. For lead-acid batteries from 4Ah to 60Ah for 24-7 battery maintenance and for lithium batteries from 2Ah to 15Ah for 24-7 battery maintenance.

Charge time on a flat but otherwise undamaged battery: a 12Ah battery should take no more than about 12 hours to progress to the self-discharge check. Deep-discharged batteries may take significantly longer, a full charge may not be achieved within the hour charge safety limit. In this case.
