This is the same great lithium battery that is in the rack mount cases. It has just been removed from the case and reconfigured for use in a frame bag. 18 month warranty and the triangle bag is included for this cost. The bag dimensions are 16″ across the top, 11.5″ down, and 17″ for the diagonal portion.
The 36 volt and 52 volt Samsung Lithium NCM Battery (Li[NiMnCo]O2 12 AH Cylindrical Cells) with a 2 amp charger provides the absolute best in quality and price. They each provide a long lasting, cost effective, battery solution. The battery is the most important component. We provide an 18 month warranty. Others say they have the best batteries, but then provide a very limited warranty if any at all. Make sure to always check the warranty before you buy.
What also makes the 52V battery a step above most others is that we use a 14s cell string/bank technology. Most other 48V lithium-ion batteries on the market use a 13s cell string system. The difference is that 14s provides an overall 4.2VDC higher operating voltage. Thus, it gives you nearly 8% more power throughout the battery discharge cycle and it adds to the battery’s overall life span.
Lithium Nickel Manganese Cobalt Oxide also lithium-manganese-cobalt-oxide (LiNiMnCo, NMC, NCM), Li[NiMnCo]O2 based Cathode & Graphite based Anode, is the newest generation Li-Ion rechargeable battery for high power applications, such as EV car, E-scooter and E-bike. The NCM cells compromise between high current rate and high capacity rate. Compared with LiCoO2 series Li-Ion cell, the NCM cells provide higher energy density with lower cost and longer cycle life. NCM cell has 3.6 +/- 0.5V nominal working voltage and is cut-off at 4.15-4.20V per cell during charging.
