What about reducing the voltage that you charge the batteries?
There are lots of studies and evidence about increasing the cycle life of the
battery cells by reducing the maximum voltage that you charge the battery to. It is
said that you can double the amount of cycle life by decreasing the charge voltage
of each cell by 0.1V. For a normal 36V battery that means the charge voltage
would reduce from 42V to 41V. This will decrease your maximum capacity by
approximately 14%, which in turn will decrease range. This can be difcult to
achieve with the current battery charger as you have to monitor the voltage of the
battery periodically during the charge and take it off charge once it reaches that
voltage. If you wish to undertake this style of charging we recommend that you
still charge the battery to 100% every week to ensure that the BMS can efciently
balance the cells.
There are many online resources and white papers explaining this information and
good tips for caring for your lithium ion battery. Battery university has lot of
information on all types of batteries and is a good place to start, just google
‘battery university lithium ion care’. Remember though to ensure that your
warranty remains intact only use the provided charger to charge your battery.
