[Jenny Mao]

Dear all friends

I hope your everything is going well.

This is Jenny from Aijiu Energy and we have been promoting the Dorado 48V 25Ah since 2021. I am very grateful that we receive a lots of positive comments here. I am posting to introduce some new upgraded ebike batteries we are working on recently.

According to the demands for the upgrading battery capacity, motor power, and smart BMS allowing battery monitoring on cell phone.
We worked with JBD BMS to develope a small size 14S50A Bluetooth BMS to support max 48V/52V 1500W rated motor. It can be used for those popular integrated battery like Rhino, King Kong, Dorado and downtube battery Polly,Hailong...

Samsung 58E helps increase the single 21700 cell from 4900mAh to 5330mAh, which means now we can build 48V 26.6Ah or 52V 26.6Ah for those case designed with 70pcs 21700.

We would be appreciated if you could send us new battery requests.

Kind Regards

Thanks for clarifying. I have the IR-5, so I’m stuck with that size. Since my battery size is limited, I think my battery can only get better if I get a blank case and use a better (than Samsung35E) cells. I’m no battery builder, so I’m sure I’ll reach out to someone like you when the time comes.

Agree, IR-5 can be 48V 14Ah max by Samsung 35E. 3500mAh now is till the max capacity of 18650 cells.
