About lithium battery
Because of this we opted for the top of line Li-NMC (LiNiMnCoO2) battery. These batteries have efficiency per weight compared to sealed dry lead batteries of 6 to 1. In other words our 6.5 kg battery has the same power output as a bank of dry cell Lead acid weighing 40+kg. Wow !!!
In a world where electric vehicles are ruled by weight, you can see why we opted for the Li-NMC batteries.
Li-NMC batteries have a typical discharge / recharge cycle rate at 80% Depth of Discharge* of over 1000 cycles and at 50% Depth of Discharge this can increase again further to 1200-1500 cycles.. The trick to ensuring maximum cycle recharges is to ensure that you have plenty of capacity to start with. Using a battery that only has minimal capacity reserve will take you to the limit and stress your battery out, effectively reducing its serviceable life and in the case of dry cell lead acid batteries this could be months instead of years. In our research some competitors have only been achieving 3 months of battery life using dry cell batteries due to the excessive loads applied to them.
The NMC cells compromise between high current rate and high capacity rate. The NMC cells provide higher energy density with lower cost,
long cycle life (>1000 1.0C, IEC standrad).
NMC cell has 3.6 +/- 0.5V nominal working voltage and shall be cut-off power at 4.15-4.20V per cell during charging.
The secret of NMC lies in combining nickel and manganese. An analogy of this is table salt, in which the main ingredients of sodium and chloride are toxic on their own but mixing them serves as seasoning salt and food preserver. Nickel is known for its high specific energy but low stability; manganese has the benefit of forming a spinel structure to achieve very low internal resistance but offers a low specific energy. Combining the metals brings out the best in each.
NMC is the battery of choice for power tools and powertrains for vehicles. The cathode combination of one-third nickel, one-third manganese and one-third cobalt offers a unique blend that also lowers raw material cost due to reduced cobalt
content. Striking the right balance is important and we keep their recipes a well-guarded secret. below figure demonstrates the characteristics of the NMC.
How to select the correct battery pakc (General Knowledge) ?
First of all, you must get to know your device:
What is device's input voltage? ( V)
What is its power consumption ( Wattage ) ?
What is Maximum current drain ( A) ?
What is your expected running time by a battery pack ?
Decide battery pack voltage you will choose
Battery pack voltage must be equal or a little higher than your device’s need.
If you need a exact voltage, which battery pack can not provide, you may consider to use a DC-DC regulator
Decide Battery pack's Capacity ( mAh or Ah)
Battery capacity is depended on how long you need to run your device ( hours ), which can be calculated as the follow:
( Ah) = Device's Wattage (W) x Time to run ( Hours) / Battery Voltage (V)
For example, if using a 12V battery pack, and run 10W DC device for 10 hours, you need choose a battery pack with capacity > 8.3Ah, e.g (10x10)/12 = 8.3
1000 mAh = Ah, higher mAh will provide longer running time.
Decide Battery pack’s Max. discharging current
Before order battery pack, you must pay attention on battery pack’s Max. discharging rating on the specification or description. Please don’t think any battery can take any current drain.
You shall know your device’s max. discharging current. If you don’t know , you must measure it by a multi-meter.
The battery pack’s Max. discharging rate of the chosen Battery must be higher than that device requires
How to Maintain Lithium Battery
Greenworks 24V Deep Cycle E-Bike Battery 24 Volt Lithium Battery Pack with Customized 12V 40Ah Battery
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 month
What 10 Tips should be note when using Lithium ion battery?
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.
