FAQ
Q:What is the advantages and disadvantages between nickel hydrogen batteries and lithium batteries?
Voltage:nickel-metal hydride battery is 1.2V,and lithium ion battery is 3.7V,lithium ion battery is triple.
energy density：
A typical lithium-ion battery can store 150 watt-hours of electricity in 1 kilogram of battery.
A NiMH (nickel-metal hydride) battery pack can store perhaps 100 watt-hours per kilogram,
Discharge rate:cylindrical li-ion battery and Nimh all support 10C discharge,but pouch lithium ion polymer discharge rate up to 100C
Temperature,lithium ion battery discharge on -20-60℃，Nimh battery discharge on 0-45℃
Weight,Nimh batteries are about 2 times that of lithium-ion batteries in same power
Cycle life,lithium ion batteries around 500-800 times and nimh batteries around 300-500times.
Memory,no any memory effect of lithium ion battery,but a little memory effect for Nimh battery
Safety:Nimh battery is more safe,lithium ion battery need to add protect circuit
Cost:lithium ion battery cost more than nimh battery
Environment:both lithium ion battery and Nimh environment friendly
