Quick question ... With a Giant EnergyPak (energypak 400 ) if you press the battery button (lightning bolt) it shows the current charge status, but I have found if I press and hold the button for about 7 secs it shows two different sets of indication lights ... does anyone know what these are...

Back in 2011/2012 I bought a "Alien Ocean Aurora" which was fit for purpose at the time but ended up being very much like "triggers broom" , same bike but new - wheels / tyres / handle bars / brakes / seat / seat post / pedals & a knackered battery ) and still weighed more than a pile of RSJ...

Thanks for the prompt reply... I will drag my bike from the shed tomorrow.... So the existing controller (behind the battery on the rack) which just takes a two wire input .... can be removed and put in "under-saddle tool bag" and then I just buy a generic "36v 10aH lithium battery unit" (e.g...

Wow... sorry just seen when I joined... 2011, so I think that might explain why my original battery might be a bit poorly (in my mind it was only a few years ago, oh dear!) Anyways thoughts best options ? 1. Try and replace the battery , plug/play and get going going again ? 2. Replace more...

I'm thinking about resurrecting my old Alien Ocean Aurora and need to replace the battery but struggling to find a straight replacement (same connection.. etc plug and ride !) for the 36v 10aH lithium battery unit. Any recommendations (links) greatly appreciated, or if you think its better and...

Sorry to jump on this thread, but I'm also thinking about resurrecting my old Alien Ocean Aurora and also need to replace the battery but struggling to find a straight replacement (same connection) for the 36v 10aH lithium battery unit. Any recommendations (links) greatly appreciated, or if...

ok thanks again for all the information, I will measure the voltage of each cell within the battery pack and see whats what. I have also ordered the Li-Po charger that D8veh kindly recommended. One rather basic question though (excuse my ignorance), how are the cells connected together ? and...

Yes your right I should of used the bike more regularly! (but that rain and snow stuff isn't nice ;-) ) I had a quick look on the Alien web site and it appears a '36V 10ah' battery is £349, I assume thats the one the Aurora uses. I was just wondering if other people had experiences of getting...

Thanks JimB Wow what a great explanation :-) I guess that the safest option will be only to measure the cell voltages (to better understand how healthy things are) and then maybe start the search for a new battery (any recommendations of who, where and what to buy) Also has there been any...

Great thanks johnc461165 I will get my volt meter out tonight and check. I assume that after charging the low individual cells every thing was balanced and ok again ? Also how did you manage to charge the individual cells ? Thanks Mark

Hi thanks d8veh, for the prompt reply Yes the bike had been running fine last year before its rest ;-). When you say 'measure the individual cell voltages', I get a little nervous of doing something stupid and ending up with a load bang and a smouldering mess. Could you describe with a...

Today I refitted my battery that I took off in November, it has been fully charged, ie I charged it every 2 months. Going out tonight I travelled 1.5 miles then the bike cut out, no power, switched off with the key, switched back on power back, twisted throttle and it cut out straight away...

Thanks for all the advice, went with a matt black 'Bern Watts' with Removable earpads ;)

Very quick question, any recommendations of safty Helmets used with 'pedelecs' (usage is on and off road , 2/3 tarmac 1/3 offroad)

Sorry to be a bit boring, but what is the distance from the bottom bracket to the top of the frame seat post ? (21 inches) or even better what is the distance from ground to the bottom of the frame seat post ?

Many thanks for the info, (any pohto's of the Aurora with the new forks ? :D )

Hi I'm considering buying an Alien Aurora, does any one know if the handle bar stem is a 'quill' type and whether its removable (also what size 1inch or 1-1/8th)? Also does any one know the battery weight ? Thanks Mark
