So as mentioned in the post I've reduced this circuit to use just one TIP122 and hence less circuitry and also lower power consumption. 15% Off Lion Energy Battery Charger Promotional Code + Free Shippoing Over $50. The op-amp in the left (IC1c) takes care of limiting the current to a maximum set with the potentiometer.Since the sense resistor is 1 ohm, the voltage across it will be the same as the current flowing through it. In this video, I update you on how it’s going with the new Lion Energy UT 1300 batteries now that I have been doing some real-world tests boondocking in the southwest.. I’ve been able to charge the batteries perfectly well with my existing Bogart solar controller and my Intelipower PD9260 converter charger … For example, you have a big battery labeled as 2400mAh or 2.4Ah, that means that it can push 2.4A trough your circuit, and discharge in an hour-long period of time. That would be a 1C discharge rate, discharging your battery at the rated capacity current. 3 months ago If you were only using only one then you would go with a 60 amp converter part # PD9160ALV but if you were using two (wired in parallel) then you would want to go with much higher 80 converter part # PD9180ALV . I made the board with two outputs, one with a screw terminal and other with a DSI battery connector, they're connected in parallel, but you should charge just one battery at a time. $19.98 $ 19. As the battery gets charged and it's internal resistance increases, less current is needed to keep 4.2v across it, so current will drop slowly. The modern state of the art MOSFET power conversion circuit efficiently and accurately converts AC power to the proper DC power levels required to charge different kinds Li-ion batteries. on Step 6, Question GTIN.
