今日岩岩買左一盤east power 4200 uv電
係應該點處理佢好?
要唔要每粒放到0.8v再差番起佢

EP4200 UV ( Ultra Voltage )

1. High capacities high electric discharges platform power battery,0.5C discharge
capacity above 4400mah

2. Charges in the 35A electric discharge situation in standard 6A The battery cycle
life achieves 350 above time In

3. Standards 35A electric discharge situation, battery discharge time above 420
seconds + , battery discharge voltage platform between 1.21V+

一般每粒放到0.9v, 攤凍後. 就一般用6A去差

唔明
35a放電??
咁鬼大a數放電

For those 4200mah cells, please dont discharge the voltage below 1V.  The over-discharge will damage your cell perminantly.  By the way, the charge current shall be less than 5.5A.  High current will cause overheat...it also be harmful to your cells.  

Use 5.5A and discharge it to voltage at around 1.1V.  Please be reminded that characteristics of those 4200mah cells are totally different from 3700, 3300 cells.  In the past, everyone said 0.9V as the golden value for Nimh Cells.  It was correct but is wrong now.  If discharge to 0.9V, your cells will die easily. Therefore, most dischargers are useless because their adjustable discharge voltage is restricted within 0-0.9V.  If u wanna buy discharger, muchmore CTXDII, TEamWave Version 2 or above, or Trinity Digital Discharger

If I am wrong, please correct me

Special Care for INTELLECT SC4200 cells

As a top-grade racing cell, its super performance is associated with fast Self-discharge feature. It is temperature dependent, and become more serious at hot environment.
If possible, it is recommended to have racing cells stored at 0~20ºC environment.
In any case, because of fast self-discharging, the Open Voltage of the cell may fall below 1.0V each. The racing performance may be affected then.
It is recommended to make periodic checking on Open Voltage of the cells. In case of being down to 1.1~1.0V level, it is recommended to recharge the cell for not more than half of its capacity (~2000mAh) for further storage.
The above information applies to battery matchers, wholesalers, retailers, and end-users in general.
For special interest of matchers & racers, they could consider to run a cycling process, and then the recharging for storage as mentioned above.
It is also important that end-users should not dead-short the batteries, or use drainage device in discharging cells <@0.9V (as Intellect cells perform differently than those of 3300mAh).

即係唔好放電大過5.5a又唔好細過1a?

差電唔好大過5.5a - Current

放電唔好細過1V - Voltage
