Golisi S35 21700 Battery

More is simply not possible

The Golisi S35 battery meets the demands of increasingly powerful energy suppliers and is our offer on the 21700 battery market. With a size of 21x70mm (diameter x height) and a weight of 46g, it is still interesting for more compact applications and delivers top values! A constant output power of 30A and peaks of up to 40A ensure appropriate performance and safety. A powerful battery with a strong 3750mAh capacity ensures long-lasting use until the next charge.

Wow

In the upper range of power output, 111 to 90 watts at 30A are no problem for the S35. The S35 battery maintains this power through an efficient design down to a capacity of 40% before it slowly collapses. In lower ranges, it always amazes with a view of the full 3750mAh endurance if it still doesn't have to be connected to the mains. In addition, the S35 can be charged more often  - Up to 800 charging cycles guarantee a long service life in connection with the large battery.

Battery safety

All Golisi batteries are developed with long and safe use in mind. The S35 has a particularly robust design that starts on the outside. An extra thick casing secures it should it fall down. This also delays the insertion and removal of the battery from chargers, which is known for rapid wear of the shrink tube, especially at the ends. Inside, an integrated short-circuit protection serves as an additional security guarantee.

And otherwise?

Numerous investigations and tests certify the Golisi S32's specifications and our claim. A packaging that consists of 99.9% recyclable materials and does not contain any air also makes the "trappings" a useful addition. In addition, you will receive a battery transport box for two 20700/21700 batteries with each S35 battery. Please never transport your batteries loose and always use a transport box.
