Customer Reviews
i have a nice memory of our meeting in Shenzhn with Deligreen Mandy and a beautiful impression of your growing company.We both are straightforward and honest people and this is the most important value,so i am sure we can

—— Angelo from Italy

I am sure we can happily work together we should easily find a way to do.Money are important but aren't the most important part.

—— Angelo from Italy

Deligreen is the partner that i have replied one for years. Some other suppliers change sales quickly but Deligreen not.

—— Bonnett from USA

i have used the batteries for 9 years from Deligreen. Amazing!

—— Phil, LA

COVID19 made something more difficult. we need the balancers urgently.Thanks for the Deligreen team's effort. We receive the balancers on time and no delay for our project. Thank godness

Support balanced cascading for battery packs, for exsample , it can cascade for 11S , 24S ,36S , 48S....and so on

As the battery battery cycle times increase, the battery capacity decay speed is inconsistent, causing the battery voltage to be seriously out of balance. The battery barrel effect will cause the battery to charge. The BMS system detects that the battery has entered the overcharge protection in advance. In fact, only one of the batteries is full, or let The BMS system detects that the battery enters the over-discharge protection state, which is actually caused by over-discharge of one of the lower-voltage batteries. After the device acts, each battery voltage reduces the capacity attenuation caused by the battery barrel effect and prolongs the problem. The battery pack has a service life.
