Test/Review of Intl-outdoor NCR18650 3100mAh (Blue)

Intl-outdoor NCR18650 3100mAh (Blue)
This battery has been replaced by Intl-outdoor NCR18650 3100mAh (Black)

Official specifications:

Panasonic 18650
Capacity: 3100mAh
Nominal voltage: 3.6V
Full charge: 4.2V

The batteries arrived in an envelope without any other protection (intl-outdoor has informed me that they have changed to a better packing, see below).

The batteries shows nice discharge curves up to 2 ampere, but 3 and 5 ampere is stopped by the over current protection.

On this curve it can be seen that the protection on the two cells activates at different currents.

I uses 3 ampere as the minimum test current, but one of the batteries had a protection that activated at a lower current.

Conclusion

These batteries uses a very good Panasonic cell and as can be seen on the discharge curves the two batteries matches perfectly, but they only works up to 2 ampere, the protection stops the 3 ampere test.
It is a bit difficult to rate these cell, up to two ampere they are good cells, i.e. they will work perfectly in lights with a single XR-E, XP-E or XP-G led, but the batteries are useless in a XM-L light, due to the low protection threshold.

From intl-outdoor I have received this comment:
Limit will be changed in the next batch. Currently working with a different company for a new protected battery.

Notes and links

The batteries was supplied by intl-outdoor for review.

Приехали. Разобрал.

Внутри действительно NCR18650A

На схеме защиты немного сэкономили. Копеечная деталь вообще-то.

а где их брали? какой ток выдерживает защита?

Ну там история такая: он начал их продавать как защищённые, на него через время начали наезжать за то, что защита маловата. Он быстренько описание поменял, самым злым птицам деньги вернул.

Может и в самом деле поставит нормальную защиту (а разница в цене там центов 20, просто второй мосфет поставить) – тогда будет мега-бюджетно

Поживём увидим

The full story:
Hank (Owner of intl-outdoor) get a batch of batteries made, where he specifies that they must have a top quality protection pcb.
He gets the batteries and start selling them, but it is soon revealed that the protection trips at to low value.
Hank changes the description in the webshop and sells the rest of the batch.
At the same time he starts to look for a new manufacturer, that can make the batteries with a better protection pcb.

Hank has promised me a set of the new batteries when he gets them, to make a new test/review.
