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

2OZ 40A Battery Management System BMS


LTO40A 20s Battery Management System BMS


1mm LTO40A Battery Management System BMS

Lto Battery BMS 5s/10s/15s/20s 40A 2.4V with Balance for 12V/24V/36V Lithium Titanate Battery Pack



1. Integrated circuit IC, from the solution of Seiko of Japan.
2. Strong load ability, constant discharge current 15A/20A/30A/40A/50A/60A , use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help cooling.
3. IC itself has power balancing function. The circuit is simple and reliable.
4. Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged. Over current and short circuit protection function is very reliable.Long time short circuit of the load won’t affect the PCB and the battery.Temperature protection during
charging and discharging.

The relationship between Battery capacity and BMS current?
There is no direct relationship between Battery capacity and BMS current, big capacity doesn`t mean a big battery, but rely on continue current, that is to say if your engine is powerful, your should choose high current of BMS, it is not relied on battery capacity.


Producttion Usage Instructions

First, the black line is connected to the total negative pole of the battery, then the first red line next to the black line is connected to the positive pole of the first series of the battery pack, and then the next red line is connected to the positive pole of the second series of the battery pack,then the next red wire connect with the related positive pole of the battery pack in this way. Measure the terminals of the connect row wire through the multimeter to ensure that the acquisition voltage is the
voltage corresponding to each series of the battery pack. Then plug in the BMS again, connect the b-wire to the total negative
pole of the battery pack, and connect the p-wire to the negative pole of the charge and discharge. Note: do not plug in the BMS
when connecting the row wire cable.
