Please use only the original Canon LP-E5 lithium-ion-batteries (#3039B001) for operating your TECNATIVES Nt Core!
The hardware design of the Nt Core was done in connection with exactly this battery. The use of this battery guarantees the safe and functional use of the Nt product.
Background of the battery problem:
The international use of the battery led to a number of replicas of the original battery. Our engineers have carried out extensive battery tests and found that some batteries cannot supply the required current at the moment of switching on. This prevents the Nt Core from starting completely. The problem with the international market for replacement batteries is that each battery manufacturer places and implements different requirements on the internal components of the battery. This means that battery manufacturers who do not use the original components (such as Canon) cannot be approved for the Nt product.
