A123 AMP20M1HD-A Lifepo4 3.2V 20Ah NanoPhosphate Prismatic Pouch Cell 20C
• High lifespan: two thousand cycles and more (see chart) • Deep discharge allowed up to 100 % • Ultra safe Lithium Iron Phosphate chemistry (no thermal run-away, no ﬁre or explosion risks) • Embedded BMS (Battery Management System) : improve lifespan AND secure the battery • No Lead, no heavy metal, no toxic element • Calendar life > 10 years • Excellent temperature robustness (-20 °C up to +60 °C) • Flexible deployment : up to 10 packs in parallel and 4 in serial • Constant power during discharge (very low internal resistance) • Very low Peukert's losses (energy effciency >96 %) • Very low self discharge (<3 % per month) • No memory effect • About 50 % lighter and 40% smaller than equivalent Lead-AGM battery with same usable energy
1.Power: Nanophosphate products can pulse at high discharge rates to deliver unmatched power by weight or volume.
Figure 1 shows the cell voltage remains relatively flat during and the delivered Ah capacity does not change significantly , no matter what the rate of discharge.
Cells resistance changes with cell temperature. The warmer the cell, the lower it's resistance becomes.
Figure 2 shows how temperature affects the cell's terminal voltage during a one hour discharge.
2.Life: Nanophosphate technology delivers calendar and cycle life. A123 cells can deliver thousands of 100% depth-of-discharge(DoD) cycles, a feat unmatched by other commercial lithium ion cells.
Figure 3 shows how the capacity of cell decreases with respect to the number full depth of discharge(DoD) cycles that it delivers. For example, at 25℃, the cell can deliver over 5000 full DoD cycles before it's capacity decreases to 80% of it's beginning of life(BoL) capacity.
Figure 4 shows how the cells lose capacity over time, sitting at 100% SOC in various temperatures. Within three months, the cell lose 3% of their initial capacity, but the aging slows, and over the next one year they only lose another 1% at 25℃. Temperature is a significant factor in calendar aging. For example i n two years, the capacity loss 6% at 25℃, 11% at 25℃ and 22% at 45℃.

One-stop battery solution
One-stop solution, Lithium / LiFePo4 battery packs, accept customized, OEM sevices, We will respond within 1 business day or less. Anyone who is open dispute without contact us , no warranty! add blacklist . No matter what problems is , we can slove them. Any questions please contact us first !
Dear Customers,if you wanna to be our long business partner,you can share your email box,whatapps,skype ,facebook etc.
1. we usually send out battery by international commercial express, UPS ,FedEx ;but now battery belong to some dangerous goods in some countries , so we send them by special line. 2. It takes 8-15 days by express send to destination ( not including the Lead Time ) ,if send by special line may takes more than 25 days. 3. Battery goods belong to sensitive items , we produce the best battery , so welcome customer come to our warehouse.
About Customs duties & taxes Important note: our products do not include local consumption tax!!!

Before taking the order
Please read carefully all the description before taking orders, the battery is suitable for DIY lovers with experience, people who are not familiar with electronic, please go to our shop to buy the finished product. Those buyers who buy this battery, must agree that you are familiar with the safe use of lithium battery knowledge.
DIY battery pack must get the cells balanced (same voltage ) before assembly. Later if there happens don't know how to assembled or unbalanced assembly is not accepted refund. please consider before taking orders, place order means you have agreed. thank you for your cooperation!
DIY assembled battery note
Professionals will detected voltage/resistance/appearance and other issues before every shipment, we can only ensure that the single battery is good, when arrival you can test the cells within 2-3 days, after that means batteries have no problem, does not provide return nor refund. If you found problems you can contact us for return or refund. Battery can only be unused (the electrode intact, no welding, no wear, the appearance good) to provide return. Any return behavior buyers need to be responsible for shipping fee.
These situations not provide return nor refund
1: after the assembly or assembly process happen any problem, such as the protection board connected to the wrong wire burned lead to battery damage, charger failure, the assembly error or unbalanced assembly, etc. 2: For damage caused , such as battery bulge/ welded, battery pack without protection BMS caused by charging. Tip: These products are batteries only, without protection board, you need to purchase a match one! You can check our shop and search BMS. Courier and logistics In addition, because the battery is prohibited product, many courier and logistics are unable to send, the arrival will indeed be slower, so please wait patiently after place an order. Can Not give us bad feedback due to the courier company or because of the courier service slow or other factors. open dispute will be unacceptable. Sorry for any inconvenience.
