I just check the whole thread and seems no one actually did the higher discharger rate mod. The back cement resistor is 5W, 0.47Ohm, with result of 2.55A under 1.2V.
I wanna mod it to 10A discharge rate under 1.2V, makes 0.12Ohm with 12W. Is that the correct cement resistor I should get?
Also, I check over the circuit and found there is an IC 4410 on the path of cement resistor, I believe it's "N-Channel Enhancement Mode Field Effect Transistor" (PDF:
http://www.ortodoxism.ro/datasheets/cet/CEM4410.pdf). It seems it can take 30V 10A maximum but with my target 10A discharge rate, wouldn't it be a bit on edge if I don't replace the IC for bigger current pass? I search over and found CED61A3 (PDF:
http://web2.cetsemi.com/PDF/TO-251-252-N/U61A3.PDF) seems fit the spec with maximum 30V 40A. Is this the correct IC I should replace original one?
Sorry I'm not major in electronic so some question might seems stupid...
Reason for such mod? I love the feature of setting cutoff voltage and I don't wanna use other 20A discharger due to many reason. Mod the Smart Tray seems the best fit way for me.
