ARK-POWER

ARK-121
1. Input voltage range 9~15 V DC
2. Output 8.4 v (4.2 v x 2) x 2, or 12.6 v (4.2 v x 3) x 1, or 16.8 v (4.2 v x 4) x 1.
3. CC (2.0A charging current) and CV(4.2 v charging voltage) charging technique.
4. Auto adjustment of the charging current at voltage peak region. Auto-cut off  when battery cell is fully charged.
5. The innovative charge for 1~4 cells of (Minimum 360 MAh) Li-ion or Li-poly  battery packs. It can be used to charge 4 ea 1 cell pack (optional by      

 

using 2 serial charge adaptor cable for port of 7.4 v), or 2 ea 2 cells pack, or 1 ea 3 cells pack or 1 ea 4 cells pack.
6. LED indicator, red for charging, green for charger ready or battery cell fully charged.
7. Instead of charging all cells of the battery pack serially, this charger will independently control the charging process of each cell of the battery pack. It will completely eliminate the interference between cells of the battery pack during charging process. It will also avoid the possibility of burning or eruption caused by a defective battery pack.    
8. Load polarity & short protection. In-put polarity protection.
9. Sturdy aluminum case & exhaust fan for maximum heat dissipation
10.Auto-cut off charger operation when voltage of the power source is lower than 8 v. All LEDs off.
11.Size : 132 x 82 x 35 mm. Weight :313 gm

ARK-122
1.This type of speed controller are specially designed to offer high power and high efficiency combined with low weight and compact dimensions.

2. Automatic cut – off and auto detection of all types and number of cells.
