Finally got A battery that works. It took 3purchases. Works great now

Good as spare

J'imagine que ce produit est adéquat. Il ressemblait beaucoup à ce que j'avais mais il ne s'adaptait pas à l'adaptateur de mes autres piles. Donc vérifiez bien avant d'acheter.

Useful addition for when the first battery for the tyre inflator runs out of charge.

Got this for an extra charge :-) This combined with the cordless drill was very reasonably priced. Arrived quickly ....will get putting both to the test soon. More to follow.

Capacity on the lower end of the spectrum but decent build and quality. Operating voltage is about 15.5V to 21V. Below that the BMS will prevent any further drain to the pack. I was able to squeeze about 20Wh out of the rated 1.3A x 20V = 26W. It's a good sacrifice in usable capacity for battery longevity and safety.
