![]() To build a battery pack with hundreds or thousands of watt hours of capacity, many individual 18650 Li-ion cells are assembled together into a brick-like structure. ![]() In comparison, Li-ion batteries have about 10X the energy density compared to lead-acid batteries. Lead-acid batteries have the benefit of being inexpensive, but suffer from having very poor energy density, meaning that they weigh a lot compared to the amount of energy they store. They are also found in some electric scooters most notably, inexpensive children’s scooters from companies like Razor. Lead-acid is a very old battery chemistry that is commonly found in cars and some larger electric vehicles, like golf carts. Some electric scooters with INR chemistry include WePed GT 50e and Dualtron models. Consequently, this reduces the chances of thermal runaway and fire. The presence of manganese lowers the internal resistance of the battery, allowing high current output while maintaining low temperatures. This battery gives high capacity and output current. Lithium Manganese (INR, NMC)įortunately, many quality electric scooters are using the INR battery chemistry - one of the safest chemistries.
