Our Similar Batteries Lithium batteries are presently the most commonly used energy storage devices on electric bike, electric scooter, golf car, mobile phones, laptops, digital cameras and other electric devices. Learning how to maintain lithium batteries can not only prolong battery lifetime but also protect your device from potential damage. 1.Charge new batteries.It's not necessary to charge over 12 hours when first used. When a device powered by batteries is purchased, sellers will usually tell us the batteries must first be charged 12 hours before using. Actually, this is unnecessary. Unlike common Ni-CD or Ni-MH batteries, most lithium ion batteries are activated before leaving the factory. Due to their low self-discharge, it’s unnecessary to charge lithium ion batteries for such a long time when new. Lithium ion batteries are ready for use when the charger indicates so, and they will reach their best capacity after 3 or 5 cycles. 2.Use appropriate chargers.Many people take great care with their electronic gadgets, but often neglect the consequences of bad chargers on their lithium ion batteries. When choosing a charger, the original charger is the best choice. If that's unavailable, a high quality charger that has an overcharge protection function, or a brand name charger will do. A low quality battery charger can lead to shorter run times, premature battery failure, or even fire or explosion. 3.Avoid frequently over charging.Over charging with a low quality charger may let the battery's interior rise to a high temperature, which is bad for the lithium ion battery and charger. Thus, simply fully charging is good enough - overcharging will make your lithium battery into a little bomb if overcharge protection function is missing. 4.Avoid touching metal contacts.All batteries' contacts need to be kept clean for best performance. When carrying batteries around, do not let the contacts touch metal objects such as keys; this could cause a short circuit, damaging the battery or potentially resulting in a fire or an explosion. 5.Avoid using often in high or low temperature environments.Lithium ion batteries have optimal working and storage temperatures. If they're continually used in extreme temperature environments, this will negatively affect battery use time and useful cycles. 6.Avoid long periods without using or recharging.If batteries will be left unused for 3 months or more, partially recharge them (to around 30-70% of capacity, depending on planned storage time), then store the device to prevent battery damage. You may need to take the device out of storage and charge again after a few months.

Warnings: Do not immerse the battery in water or seawater, and keep the battery in a cool dry surrounding if it stands by. Does not use or leave the battery near a heat source as fire or heater Use the battery charger specifically for that purpose when recharging. Do not reverse the position and negative terminals. Do not connect the battery electrodes to an electrical outlet. Do not discard the battery in fire or a heater. Do not short-circuit the battery by directly connecting the positive and negative terminals with metal objects. Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc. Do not strike, trample or throw the battery. Do not directly solder the battery and pierce the battery with a nail or other sharp objects. Enjoy your Shopping! Friendly Tips: Material: LiFePO4 (Lithium Phosphate ion), Li-CO2, Li-NiCoMn(ternary battery), Li-MnO2. The price is from high to low. LiFePO4 cost is most expensive but the security and stability is also highest. Li-CO2 cost is lower than LiFePO4 Higher than Ternary and Li-MnO2, the life is more than Ternary and Li-MnO2 100-200 times. Li-NiCoMn(ternary battery), the cost-performance ration is high and the technology also is mature. Li-MnO2 is cheapest but the life is short. Nominal voltage: LiFePO4 is 3.2-3.3V (the highest voltage is 3.75V), Li-NiCoMn is 3.6V, ternary and Li-MnO2 is 3.7V (highest voltage is 4.2V) Battery combination: series increases voltage, parallel increases capacity. For example 3.7V 2A battery 10 series 6 parallel, the voltage is 37V (10*3.7), capacity is 12Ah What is BMS ? A Battery Management System (BMS) is any electronic device that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting those data, protecting it, controlling itsenvironment, and / or balancing it. A BMS may monitor the state of the battery as represented by various items, such as: * Voltage: total voltage, voltage of periodic taps, or voltages of individual cellsTemperature: average temperature, air intake temperature, air output temperature, or temperatures of individual cellsState Of Charge (SOC) or Depth Of Discharge (DOD): to indicate the charge level of the batteryState Of Health (SOH), a variously-defined measurement of the overall condition of the battery * Air flow: for air cooled batteries * Current: current in or out of the battery. Hope that it helpful to you for shopping. For this 48V 20Ah Lithium Battery: Recommend to use for 48V 100W -48V 1440W Motor. The Charger applys to 100V-240V voltage.
