Considering a 2 cell 18650 LiIon battery pack solution? After design considerations for temperature extremes, cycle life, and cost, a single cell solution from Boston Power may be your best solution!
The 2 cell 18650 LiIon battery pack is a common solution for many OEM applications. But with careful consideration Boston Power’s single cell Swing 5300 or Sonata 5300 may ultimately be a better solution.
• Both solutions are 3.6V with overall capacity 5.3Ah ( 18650 cells strapped in parallel)
• Both the 2 cell 18650 pack and the single cell Swing 5300 and Sonata 5300 fit in the same mechanical package
• Boston Power offers wider temp range: Storage Temp -40 to +60 C
Operating Temp: Charge -20 to +60 C
Discharge -40 to +70 C
•Boston Power offers greater cycle life: 100% DOD > 1,000 cycles
90% DOD > 2,000 cycles
80% DOD > 3,000 cycles
Cost is comparable, and at times lower than, 2 18650 cells. This is a function of volume, safety circuit needs, pack configuration, and other factors.
Some applications really like the simplicity of a single Sonata 5300 or Swing 5300 with the added feature of greater temperature range and increased cycle life.
