1. Thanks for the advice. I have a similar 36V battery pack I could use as a DC power source. Would apreciate your advice on resistor value to apply. 2. Great detective work! Yes I'm in Sydney. Would love to take you up on the offer - I'm sitting perilously on the edge of my technical ability...

Apologies to those who have already viewed or responded to this. I originally posted in 'E-bike technical', however with only 3 responses I thought that 'Battery Technology' might be more appropriate. I've got a near new 36V/8AH LiFePO4 pack that has been in storage for a while and has gone...

Thanks for the input so far. Here is more information. When measured at the battery socket the voltage is negligible - hardly enough to move the needle. I decided to take the whole battery pack out of the packaging and found that there is 20V+ on the other side of the circuit board. I tried to...

I've got a near new 36V/8AH LiFePO4 pack that has been in storage for a while and has gone flat. As the charge has drained below a certain level, the electronics are now preventing the battery from being charged. I've heard of someone being able to 'jump start' the battery and therefore fool the...

I have a 36V LiFePO4 battery for an electric bike. The on/off switch was faulty and as far as I can determine the battery is OK. The manufacturer sent me a replacement battery top with all wire connections marked. Re-connecting the battery looks easy enough but is there anything I should be...

I have a 36V LiFePO4 battery with a faulty key switch. The battery works intermittently when you jiggle the switch. The manufacturer kindly send me a replacement battery top (with new switch etc in place) but I'm a bit nervous about replacing it. Is there anything in particular I need to be...

Thanks for all the comments so far. The manufacturer says range is 32km to 35km without pedalling for the LiFeP04 batteries. Slightly more for LiPo. Also the LiPo are rated for 500 recharges, the LiFeP04 are rated for 1,000 recharges. I'm leaning towards the LiFeP04 batteries at the moment based...

I have the option of selecting a 36V 8AH LiFeP04 battery or a 36V 10AH Lithium polymer battery for my ebike. Range is important. To be used with a 200W hub motor. LiFeP04 costs a bit more but not much. Would be interested in the Forum's recommendations on this one. :roll:

I have personal experience with these bikes - the L1 is also sold via http://www.electric-bike.com.au in Australia. The battery weighs 3kg, which is about 7ibs so this is correct.
