I purchased an Alien Ocean 36V 26" kit in October 2009 and attached to a Haro Heartland DLX comfort bike. Everything has worked fine until recently when I have experienced a complete power failure on a regular short ride. This has now happened twice in roughly the same place suggesting perhaps that the battery is starting to lose its effectiveness. I have not done many miles in total over the past 21 months and have kept the battery charged up as recommended during the winter time. If I wait a few minutes I get the power again but this only lasts for a few yards and then power loss which is accompanied by an erratic flashing of the 5 spot power display. I also get increased whine from the motor before the cut out. It seems a little early for a failed battery in view of the distance I have done since new and the number of charges but I would welcome any thoughts from readers.
Alien Battery problem?

Hi the battery has lost its capacity this is caused by both use and age chemical reaction

It is possible there's a loose or broken connection inside the battery. Charge it up, put it on a voltmeter and then give it a good shake! There's another thread on here from a few weeks ago about somebody who had a BMS wire come loose. I've had a tab linking two cells break. All on Alien Phylion batteries. These things are often fixable, but please BE CAREFUL.
Jbond - Many thanks for the suggestion. The connector is the standard one supplied by Alien with the kit and I have checked this and all wires seem secure so it may well be as you say a loose connection in the battery. I will look into this and many thanks for your help.
Hi
yes the connector is different but the supply the plug to fit on the battery feed to the controller in the Charger box along with a new slide plate for the battery

Hi
I totally agree if you get it wrong you will have a fire on your hands as the battery is nearly 2 years old it is not worth repairing against the cost off a new one with 2 years service life .
It is a sorry state of affairs but most electrical items are throw away when they are out off warranty as the cost off labor is so high and the new model if far more advanced
Battery's are a consumables and it looks like 2 years is about average life span of usable capacity

Guys thanks for your help. I am not proposing to do anything to the battery. I will however need to purchase a new one and wonder if there are any better ones that would fit the Alien rack. Alien replacement batteries are currently out of stock
Alien replacement batteries should be back in stock from next week along with there new 350w bikes and kits.

Thank you Bigroy and jbond. It will probably be easier for me to get a new battery from Alien if they will shortly be back in stock although purchasing one from BMS in China would be cheaper. I am becoming tempted to maybe invest in a new bike possibly the Aurora or Wisper 905se rather than getting a new battery as it will be in the region of £350 and this money could be put towards that. I will have to have a few test rides to see if a new purpose made bike would feel different to a kit. I am more interested in range rather than speed so I will have a good look into things.
