I have already posted a question about putting AGM batteries together in a case/box and had some really helpful answers. I have another question about the batteries themselves and wanted to put it as a separate thread.
I am converting a small motorbike for my young son to electric from petrol and it will be powered by a 48v 800w hub motor. I have been tossing up between agm batteries and lithium. Agm ones are fairly cheap ,safe but fairly heavy (16kg for four 12v) Lithium are expensive , light but have been known to catch fire. Lithium have a pretty long life and a lot of charging cycles. I am actually more keen on using deep cycle AGM batteries for a number of reasons but can anyone tell me how "efficient" they are. I have been told that a 15ah one will lose power fairly quickly and that after a while just go down to 50% whereas lithium will go on on a good power until it has no charge and then stop suddenly. Can anyone let me know about the efficiency of AGM batteries and any experience with them and whether they would work for me. Thanks
