Dear Davide, I leave you in Vivian's hands, I'm sure you will come to an agreement., Vivian is professional in our product.

—— 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.

1

 

Vibration Test

振动测试

Fixed the cell to vibration table and subjected to vibration cycling that the frequency is to be varied at the rate of 1Hz per minute between 10Hz an 55Hz, the excursion of the vibration is 1.6mm. The cell shall be vibrated for 30 minutes per axis of XYZ axes.

将电芯固定在振动台上,沿X、Y、Z三个方向各振动30分钟,振幅1.6mm,振动频率为10Hz~55Hz,每分钟变化1Hz。

No leakage

无泄漏

no weight loss

无失重

no short circuit

无短路

No fire

不起火

No explosion,

无爆炸

2

Altitude

Simulation Test

高空摸拟

The batteries should be stored at the pressure of 11.6 KPa or less for at least six hours at ambient temperature 23 ±2 ℃.

No leakage

无泄漏

no weight loss

无失重

no short circuit

无短路

No fire

不起火

No explosion,

无爆炸

3

Short circuit

(短路试验23±2℃)

Each test sample battery, in turn, is to be short-

circuited by connecting the (+) and (-) terminals of the battery with a Cu wire having a maximum resistance load of 0.1Ω.Tests are to be conducted at room temperature(23±2℃ ). (在常温下约23±2℃依次把每个样品电池的正负极用铜线连接起来使电池外部短路--线路总电阻不超过0.1Ω)

No explosion

无爆炸

No fire

无起火

4

Impact

(冲击试验)

A 56mm diameter bar is inlayed into the bottom of a 10kg weight. And the weight is to be dropped from a height of 1m onto a sample battery and then the bar will be across the center of the sample.(用一条直径为56mm的圆棒放置在电池中央,将一10Kg的重锤从1m的高度垂直落下在电池的中心位置)

No leakage

无泄漏

no short circuit

无短路

No fire

不起火

No explosion,

无爆炸

5

Free fall

(跌落测试)

Fresh batteries; Height: 1.2m, 6 times; Each direction two times; Concrete floor(每个样品电池从1.2米高处自由落体测试6次。)

No leakage

无泄漏

no short circuit

无短路

No fire

不起火

No explosion,

无爆炸

6

Over discharge

(过放电)

Complete discharged battery, connected in series with two fresh cells and resistor load 3ohm for 36h or cell temperature returned to ambient. (一个完全放电的电芯被强制性串联同型号的新电芯,串联的新电芯数目=串联应用的最大数目-1。当完全放电的电芯与特定数目的新电芯串接好后,连接1个3欧姆负载36小时。)

No explosion

无爆炸

No fire

无起火
