Batteries for Volto electric bicycles

About the Lithium Battery production:

lithium battery

The construction of lithium batteries is far more complex and technical than for old lead acid batteries that we are more used to. Even though the technology is new and is developing its performance is so impressive that it is both trustworthy and efficient beyond anything previously seen. Up until now, we have only really seen lithium batteries in laptops and mobile phones. Any current user of lithium batteries should be able to vouch for their superiority. As a result of development and demand we can only expect the price of lithium batteries to drop rather than increase.

Storage, maintenance:

If you are not using the battery and the battery needs to be stored for an extended period like winter time, remove the battery from the bike and keep it in a dry area.
The battery should be charged a minimum of every three months.
If the battery is left for long periods in a discharged state, it will permanently reduce the capacity or even destroy the battery.

Optimum operating temperature range when charging: 0~45 degrees. Optimum operating temperature range when discharging: -20~45 degrees. In low temperatures all batteries loose part of their capacity but it restores when it gets warmer again.

Never disassemble the battery!

Never short circuit the discharge or charge terminals of the battery!

Never charge the battery by discharge terminals or discharge the battery by the charging terminals!

Lithium manganese oxide (LiMn2O4) is the battery used for Volto electric bikes in nz. It is the best choice for commercial Li-ion batteries application because of its energy density and long cycle life. They don't explode so it's safe to use them for large battery packs.
