Low-heat lithium-ion operation

Lithium-ion chemistry keeps heat output modest during normal charge and discharge cycles. The pack draws power only while charging and presents no acoustic noise. Calibrate by discharging to 5 percent then completing three to four full cycles if the system does not recognise the new cell immediately.
