It was solely a matter of time before smaller lead-acid batteries started to be replaced with Lithium Iron Phosphate (LiFePO4) batteries. This lack of satisfactory voltage regulation implies that with some cautomotive trickle chargers you might see the voltage climb to nicely over 15 Volts because the Lithium Battery will get close to full charge. The primary Extended Auto Warranty era of cells used in Lithium Motorbike batteries that came in the marketplace in 2010 used the perfect cell know-how obtainable at the time. For that reason most of our clients never buy a mains powered lithium charger.
The best way to take care of the charge in a lithium battery is to trip your bike and let your bikes charging circuit and the BMS in the battery do their factor. If you happen to want to cost your battery throughout lengthy intervals between using your bike, you can periodically cost it with a mains charger. Charging cells to shortly will even significantly reduce the lifetime of any kind of battery.
Trendy lithium batteries such as the Ultrabatts have fuses contained in the battery between the constructive terminal and the lithium cells. With an inbuilt BMS you can cost your lithium battery straight from the bikes alternator with Engine Parts out shortening their life and you will never have to balance the cells with an exterior BMS system. As each cell in a lead acid battery charges, the inner resistance of the cell will increase.
As you will see by incorporating an inexpensiver BMS (Battery Managment System) and clever design all of those elements may be mitigated. Sadly (from a charging perspective)with the cells in a LiFePO4 battery the precise reverse happens. Likewise dells in all kinds of batteries (lead acid, nickle metal hydroxide and Lithium) cells which are constantly over charged also will final years less than cells which might be consistenltly maintaind near the right full charge.
The Ultrabatt Lithium Battery alternative for the same bike is rated at 270 Chilly Cranking Amps and 360 PCA! Whereas a lithium battery mighte survive charging rates over 15 volts for brief durations of time you might will in all probability be unknowing be shortening it is lifespan. The sixteen a/h yellow Motobatt battery above is from a Ducati 900SS and weighs over 5kgs and is rated at 200 Cold Cranking Amps.
