OptiMATE Lithium 4s 0.8A, TM-471, 8-step 12.8V 0.8A sealed battery saving charger & maintainer

This specialized charger is incredibly smart. It has many protections on board to prevent overcharging or any other problem. I had to disconnect the battery cables completely from the bike, to the battery before the charger would begin charging. A minor drawback for safe charging.

Put a lithium battery in my Kawasaki Mule; big difference in starting. Bought this to make sure it starts every time, no matter how cold or how long it has been sitting. Solid product that protects your battery investment.

I have been into motorcycles for many years and that means I have been into motorcycle batteries a long time too! Lithium batteries are far superior for motorcycles. All aspects are enhanced-- less weight, no liquid acids, mount in any orientation, smaller yet more powerful, hold a charge and last much longer. Charging is different for Lithium and their are many motorcycle battery chargers out there for them. I have tried the upper tier of chargers and OptiMATE is a solid A+. The most sophisticated of the bunch and exceedingly easy to use. They have been in the business for a long time.

This thing is extremely advanced. Many other lithium chargers are just maintainers, but this will actually charge and rebalance cells. I have 3 motorcycles with lithium batteries and this 4 bank is perfect. I have tried SEVERAL other chargers but this one is the BEST.

If it go in the the BMS mod just leave it plug into what you want to charge and unplug the optimate and plug it back in it will start charging again

Been one of the best chargers I used. Much better than battery tender

Even though the output is on the lower side it does the job and is compatible with all Lithium batteries.

Very good
