An Introduction of Unitedcells* Big Capacity Batteries
We started our big capacity batteries* designing and manufacturing project in the spring of 2006 according to an E-bike partner*s requirement. Later we have made a big progress on this field and got more and more enquiries regarding the big capacity batteries. And right now our products are widely used in the fields like Robot, E-motor, E-car, ROVs, UPS. Etc.

1. Optional Single Cells: 30Ah, 40Ah, 50Ah, 80Ah, 100Ah;
2. Optional Packs* Voltage: 37V, 48V;
3. Optional Output Voltage: AC220V, DC37V/48V;
4. Optional Single Module*s Output Power/Current: AC Power≒3KVA, DC current≒200A;
5. Optional Human-Machine Interface: CRT display, LED display, LCD display;
6. Optional Outside Communication Port: RS232, RS485, CANbus;
7. The other special functions are available according to customers* requirement;

48.1V/100Ah (58.2kg, 540mm℅330mm℅300mm)

Function Description

This battery module uses a SCM and the specially designed Li cell manage chips to monitor every single cell*s voltage, charge/discharge current and the inner temperature of the module. It has the over-charge/discharge protection, over-current protection, over-temperature protection, short-circuit protection functions. And the Values could be re-programmed. It could display its working statues on a Human-machine interface.
And this battery module could be easily parallel connected (2~8 modules) to get a bigger capacity. Meanwhile can be moved separately to keep its flexibility.
The following are its detailed functions:
1. Optional Single Cells: 30Ah, 40Ah, 50Ah, 80Ah, 100Ah;
2. Optional Packs* Voltage: 37V, 48V;
3. Optional Output Voltage: AC220V, DC37V/48V;
4. Optional Single Module*s Output Power/Current: AC Power≒3KVA, DC current≒200A;
5. Optional Human-Machine Interface: CRT display, LED display, LCD display;
6. Optional Outside Communication Port: RS232, RS485, CANbus;
7. Optional Packs No. (Parallel connected): 1~8
8. The other special functions are available according to customers* requirement;
