High quality Cell with long life and high cycle stability. Four Panasonic/Sanyo NCR18650GA lithium-ion cells welded in series.
Keeppower 4S1P Li-Ion battery PCB/BMS protected with cable connection.
Protection circuit 4S BMS from Seiko (Made in Japan) with connection cable for temperature (white). Seiko Protection/PCB with short circuit, overcharge and deep discharge protection.
Removing the plug does not void the 2-year functional warranty.
Please note that removing or damaging the protective electronics (PCB) may cause a short circuit, fire or explosion.
Lithium-ion batteries are thermally stable and are not subject to memory effect. They work on the basis of lithium and are characterised by a high energy density.
