When the battery voltage exceeds N * 3.7 V, it will illuminate 3 blocks of electricity quantity
When the battery voltage exceeds N * 3.9 V, it will illuminate 4 blocks of electricity quantity
When the battery voltage is less than N * 3.3 V, the 4-block display will be off; represents a battery less than 3.3 V, and you can charge the battery
The crimper has been received on the 2nd day after placing the order. I was initially sceptical to make payment in advance but proceeded anyway. Unfortunately the dies of SN-28B were deformed. I contacted the team through WhatsApp and they replaced the dies within two days with no extra charge for shipping. The shipping speed is really great. I put the crimper to test, they really made great crimps for my automobile harness. I am great satisfied with the purchase.
Worked beautifully.
The product photos show a group of three pens. One is likely to be misled that one gets three pens for Rs.40/- but one gets only one pen for Rs.40/-. The thing that sucks is that the pen costs Rs. 40/- but shipping costs Rs 90/-. So while ordering this pen, order as many other parts/components you will need to spread out the shipping on a large number of components.
