Battery Operation Instructions
1. Charge:Connecting the battery pack to the charge controller, connect the charger to recharge.
2. Discharge:Connecting the battery pack to the load ,connect the load to discharge.
3. When you combine the battery with series or parallels, if there are oxidation layer on the surface, you
should brush surface to the metal glow with thin steel brush to lower the connective resistance to the minimal resistance.
4. When combining with many batteries, if the voltage between the two electrodes is over 48V, the safe
voltage for human beings, to guarantee the safety, you should not touch the two electrodes with your body.
Q:How many years will my battery last?
A:The average rider can use a lithium battery for 2-3 years before feeling like it needs to be replaced. This depends on riding conditions, the weight of the rider, amount of use and discharge rate over time. Discharging your lithium battery quickly under high current will lower the battery capacity over time.
Q:How should I charge the battery?
A:To achieve the longest life from your battery it is best to charge the battery after each use or at least once daily if used every day. It should also be charged once every month if not used for a long period of time. All bikes come with smart chargers which stop charging when the battery is at capacity, so it is okay to leave you bike plugged in at all times.
Q:How can I tell that the battery is completely empty ?
A:All of our batteries are fitted with a display showing the battery level. If your battery is completely empty, the display will not light up, as it runs on the battery.
Q:Do I need to wait for the battery to run out before charging it ?
A:No, this is not necessary as lithium-ion batteries do not suffer from the "memory effect"
Q: Can I get some samples?
A: Yes, sample order is available for quality check and market test. But it's not free.
