Hi Freelancers I would like for you to design a battery charger and balancer all in one. It will be designed to charge and balance a lipo battery through the balancing leads only. Previous experience with lipo batteries will be appreciated. It will basically be a 6 cell version of this [login to view URL] Input will be from 5 - 14 volts Output will be 25.2 volts to charge a 6 cell lipo Current output will be limited to 1 - 1.5 amp Device will be permanently connected to the battery and will need to have low power consumption The device should light an led and stop charging if too much of an inbalance is detected or another fault with the battery is detected A boost converter similar to the lm2577 should be used Readily available and cheap components should be used Reverse polarity protection is required Once the design is finished i will have sample boards made and sent direct to you for assembly and testing. You will then be required to send me a completed sample that i may test. You will need to order you own components for this. Thankyou for your time
