4. 6 Pin Balance Connector Extension w 10 Color Coded Wires 2pcs OPTIONAL 17 Beginning with the charge lead equipped with a male Deans connector connect the negative lead to the negative female banana plug receptacle of port 1 Then connect the positive lead to the positive female banana plug receptacle of port 2 Next connect the male end of the separate positive lead to port 1 and one of the male ends of the separate negative lead to port 2 as shown in the photo With a balance connector adapter board connected to each balancer port on the charger connect 1pc of TP6P10E 6 Pin Balance Connector Extension w 10 Color Coded Wires to the 4 5S Thunder Power connector on each board this step is optional as you can also connect the balance connector leads from the battery directly to the adapter boards however the relatively short lead lengths can make this somewhat difficult Now the most important step is to ensure that the balance connector labeled as Group A on the battery is connected to the extension balance connector adapter board connected to port 1 this is because the main negative ground wire lead from the battery is also connected to port 1 Then connect the balance connector labeled as Group B to the extension balance connector adapter board connected to port 2 The battery is now connected to the charger properly and ready to be charged and please note that if you mix up the balance connector connections per p

MEMORY PROFILE so you can fine tune the end voltage of the battery just as you can the chemistry type capacity and charge current rate This is helpful because sometimes batteries of the same cell count and capacity but different internal resistance performance levels may charge to slightly different end voltages when using the same charge end voltage value In those cases it may be helpful to have the same chemistry type cell count capacity and charge current rate values but different charge end voltage values in two different memory profiles To adjust this value simply press the ENTER button once and the value will flash Then use the buttons to increase decrease the value per your preference and or the guidelines listed below 25 LiPo batteries and Lilon batteries with a nominal voltage of 3 7V and full charge voltage of 4 2V per cell you can set the charge end voltage up to 4 24V per cell And although the maximum recommended charge end voltage per cell is 4 235V due to slight variations in the components and calibration of each charger resistance of charge leads and cells batteries ambient conditions and more it is possible that when the value is set to 4 24V it will not actually exceed 4 235V per cell when checked with a calibrated Digital Volt Meter DVM We first recommend charging with the value set to 4 20V per cell then checking the actual voltage per cell with a calibrated DVM DO NOT use a non calibr

We also recommend using 10 to 14 AWG wire leads when charging at rates 10 amps and higher minimum 16 AWG at rates up to 10 amps and minimum 18 AWG at rates up to 5 amps Please also be certain to connect all batteries with the proper polarity as marked on the faceplate label and further identified by the colored rings around the banana plug receptacles red is positive and black is negative And in the event that you do connect the battery with incorrect polarity the error message Battery Reverse Polarity or Battery Polarity Inversion in earlier version firmware will show on the screen However in order to prevent all possibility of damage to the charger and or battery you should always exercise care to ensure proper polarity when connecting batteries Also DO NOT connect the battery to the charger when the charger is powered off The charger should always be powered on before connecting the battery BALANCER CONNECTIONS for LiPo Lilon LiFe batteries The TP820CD is equipped with built in balancers for LiPo Lilon LiFe A123 cells batteries There is an independent balancer for each port as marked on the faceplate label and you should ALWAYS use the balancers when charging LiPo Lilon LiFe batteries for maximum safety and battery performance longevity The balancers working in conjunction with the charger perform functions similar to the safety circuits found in the LiPo Lilon LiFe cells batteries for cell phones laptop and
