20Ah 12.8V LiFePO4 Battery Pack 4S1P For Electrically powered wheelchairs,Motorcycles, Electric Scooters

 These li-ion cells and batteries not only have high capacity, but can deliver high power. High-power lithium iron phosphate batteries are now a reality. They can be used as storage cells or power sources. 

In addition, Lithium Iron Phosphate batteries are among the longest lived batteries ever developed. Test data in the laboratory show up to 2000 charge/discharge cycles. Our cells typically have more than 1000 cycles in service.

These batteries are excellent for use in motorcycles, snowmobiles, jet skis, etc., (see applicaiton note below) because they do not need maintenance during the off season. There is no equivalent to sulfation and the batteries can be stored in any state of charge without worry of degradation. We recommend 50-100% charge before storage. Another advantage is that running the battery completely down (i.e. leaving the parking light on for a week) will not damage the battery at all, unlike the SLA and Gel batteries.

Advantages and Benefits:

• Longer battery life - will last 5x longer than an equivalent SLA or VRLA battery
• Lightweight - 1/2~1/4 the weight compared to lead acid batteries
• Can be safely charged with a lead acid battery charging system
• Safer than traditional lithium ion batteries, hermetically sealed
• Low self-discharge
• No memory effect
• Maintains higher voltage during discharge than lead acid
• Can store at any state of charge without degradation
• Wide temperature performance
• Built in short circuit protection
• Built in over charge and over discharge protection
• Built in over current protection
• Product Type: Replacement for 12V 17Ah Lead Acid Battery
• Applications: Perfect for motorcycle starter, 12VDC power, medical equipment, LED light power supply, solar power

Note: these can be used in parallel to increase the capacity,  they can  be used in series to increase the voltage.

** Application note: Starting small engines. This battery will source 100+ amps during engine starting, which is over one horsepower. This is plenty of power to start most small engines. HOWEVER we have found that this might not be enough to start some high compression engines, particularly motorcycle racing engines and even some lawn mower engines. Please verify the current you need before ordering, because we will charge you a 15% restocking fee plus shipping if you return it.

How to Maintain Lithium 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 months.
