[QUOTE="oexing, post: 108347, member: 1493"] Glen, big question to your problem with the LiFePo4 battery is, what was the root of the defect and what was the consequence ? I´d rather believe the Podtronic went over the Jordan and only then the battery was cooked with overvoltage. Anyway, I will get some motorbike rectifier from Aliexpress, for three phase brushless generators - three yellow wires/three phase motor - output into two wires positive and negative 12 V - more like 14 V in fact, I guess, for charging a battery. You can get them for 15.- to 25.- €€ and I expect them to handle all overvoltage coming from the 24 V or even 48 V AC brushless motors. A test will show, no big deal if the electronics send smoke signals. I could go for a 48 to 12 V converter anyway, but a motorbike rectifier would do both jobs, the converting of AC output from the brushless motor to DC plus limiting voltage to 14 V for battery charging. The Podtronic is way overprized at € 80.- something . The typical modern motorbike alternator is mainly a three phase AC alternator, a large sort of flywheel with magnets in its rim, rotating around a set of coils . The current from three sets of coils is fed into - well, the motorbike rectifier. The small China brushless motors are basically the same principle, only the positions are changed: The magnetic rotor spins in the centre and the sets of coils surround the rotor. And yes, I could have the Alton any day , for an acceptable sum. But then, I like to be creative and think about things someone else may not yet have come upon possibly. So especially in a forum more brains might come to even better ideas to benefit our community ?
