If you want to make "outdoor feeder", Refer to my diy info.
1. CC CV board, high efficiency.
- recommendation : LTC3780 cc cv.
- You can buy it here : Aliexpress.com(Blue color board)
2. High current Cable & terminals.
3. Set output current at "6A~6.5A"
- recommendation : 6A.
- As circuit board heating up, circuit protection function will operations. it cause decrease current rate. But, cooling down the board, it cause increase current.
It means that there will be a large error in the current output in winter and summer, and a small current is sacrificed to ignore this margin of error.
4. Set output voltage
- The higher the output voltage of the board is than the battery voltage, the faster the charging speed becomes.
- Ideally, board output voltage should be set higher than the battery voltage by 0.5v.
5. Note :
A. approximant over the 7A, battrey protection board will Cut off your force feeding.
B. If you contact the reverse polarity(reverse the + and - pol), it cause high power short and spark. or cause break your battery.
C. Force feeding is very high amount of current flows. Must need a large cable and You need a terminal that is well connected.
------
Effect the feeding :
Fastest charge. 15% -> 100% takes about 40 minutes.
