—— Davide Bet

Here is the signed PI. Thank you , We hope

—— Mr Ander

12V 110Ah battery pack for solar product I like your solar battery pack. Good quality and delivery fast.

—— Eyal Dolev

The battery pack is more atractive for us . May I receive drawing of other pack 12V 20AH with dimentional info ? I need 50pcs to test .

—— Nizamettin

We have received the battery packs and performing tests have passed . We are impressed by the assembly. it is almost the best one . thank you

—— Alexander Kozhushko

Pictures show a nice battery pack, performance is ok , We need serial connected 4cells (4S1P) configuration with protection circuitry

—— George Komisar

big thanks for your work, we got the cargos last week, it seems nice.

—— Johnny Black

I think it is a good idea to solve the problem, I am really appreciate you would like to help us.

—— Simone Kowalk

yes , we received the batteries and chargers last Friday, Everything looks great,well packed, no damage and dlivered in the time frame as promised.

—— Met vriendelijke groet

Thanks for your input, we have checked each and every think and on our side every thing is great. Just proceed to submit the company documents to get approval.

French research institute CES promotes 3-in-1 battery pack Single-cell faulted battery pack still works

3-in-1 battery pack Single-cell


Whether running wearables or powering electric vehicles, battery life is a matter of great concern to system designers or consumers. The innovation in battery technology has evolved very slowly compared to the achievements of the electronics industry. In the smart phone space, design engineers spend a lot of time and resources trying to improve the battery management system (BMS). However, no one has considered integrating the BMS, charger and inverter directly into one battery pack. According to foreign media reports, the French Institute of Atomic Energy's Electronic and Information Technology Laboratory (CEA-Leti), located in Grenoble, France, put forward the idea. At last week's International Consumer Electronics Show (CES), CEA-Leti showed its three-in-one battery pack.

Philippe Despesse, head of the Internet of Things and Energy Systems at CEA-Leti, said the lab's innovative battery technology, called Sigma Cells, has received 15 patents that address a fundamental problem facing today's batteries, today's batteries. Once a battery cell stops working in the group, the entire battery pack will malfunction.
But Sigma-based battery packs have conversion, charging, and BMS capabilities that provide direct access to individual cells at any time. Cell-to-cell conversion technology selects the cell with the highest charging efficiency and will be the first to use it to ensure optimal cycling. When a battery cell fails, the battery pack can find an alternative way for the Sigma cell to avoid the entire battery pack failure.
Sigma cells are smaller, lighter and last longer. According to CEA-Leti, battery packs with integrated chargers and two-way systems can increase the charging speed of off-grid battery packs by more than 20% without additional cost, and can be charged on all standard outlets. In addition, the Sigma battery pack reduces the size of the battery pack by 20% and energy savings by 30%. Battery technology consisting of Sigma cells can be used in a variety of electric vehicles such as electric vehicles, electric bicycles, drones and boats.
