ANSMANN has a wide range of standard Li-Ion rechargeable battery packs, which are also available in small batches. All battery packs are based on standard Li 18650 cells and undergo a UN transport test (UN 38.3) as standard. Different variants in parallel or series connection provide the right power supply for practically every application. Lithium-ion batteries are the energy source of the future. With about twice the energy density of NiMH cells and a very low self-discharge, this technology is the optimal energy source for all kinds of applications. Li-Ion battery packs are thermally stable and very resistant to cold. The built-in protective circuit protects against overcharging, overload, short circuit and deep discharge. https://elecena.pl/product/29674198/2347-3008-20-lithium-ion-rechargeable-battery-pack-3-63-v-3500-mah-1s1p 2026-01-08 https://elecena.pl/product/29674198/2347-3008-20-lithium-ion-rechargeable-battery-pack-3-63-v-3500-mah-1s1p 2026-02-07
