Характеристики



Product Description


advantage of  super capacitor battery
1) The cycle life shall not be less than 20000 times. It's OK after ten years.
2) Safe and reliable: not easy to catch fire or explode. Much safer than chemical batteries.
3) The energy density is 75-220wh/kg. Small units are powerful.
4) Fast charging: charge 80% in 5-15 minutes.
5) Operating temperature range from -40 ℃ to 70 ℃. Suitable for harsh conditions.
6) Cost effective: no replacement for many years. One time investment
