Battery charger query

[7cfm]

I recently purchased an additional battery and charger from Kudos to use in Parallel with an existing battery on my bike. When I charge the new battery the charger indicates red as expected, but when it’s fully charged the light continuously flicks red/green/red/green etc.

Is this normal? I have two Kudos chargers and they both behave in the same way. This is my first lithium iron phosphate battery, the other 3 bike batteries I own are all lithium manganese and all show a steady green light on their respective chargers when fully charged.

I have a Kudos bike. The charger light is red when you first start charging, then as you've noticed it flickers red/green. If you leave it on it will eventually stay green. I don't know if it's fully charged when it's flickering but it will eventually stay green.

Hi It sounds like the battery balancing the individual cells I would Give Kudos a call and ask the question

They are the experts on there battery and chargers

Thanks both, I will try and leaving it charging overnight tonight and see if that sorts out the flickering.

Not sure if you should leave it all night ?

Maybe an hour or two and turn it off before you go to bed.

Hi We recommend with our battery's you leave them on for 12 hours the first 6 charges to balance out the cells in the battery

Thanks Frank, thats useful to know. I'll check it before bed and if it hasn't settled down I'll see whats its doing in the morning.

I've never checked how long mine flickers for but it's not long, certainly not all night. If I spot it flickering I just leave it a little while and it is green and the charger is cool. Most times I never see it flickering as it's went green and it's finished charging by the time I look at it. I wouldn't worry too much about it.
Of course, you know you've now got my curiosity up and next time I'm charging, probably tomorrow, I'll try to keep an eye on it.

I've just realised, I won't be charging tomorrow. Tomorrow is my wife's birthday, it might be a good idea if I don't go out to play on my bike.

I've just realised ..... Tomorrow is my wife's birthday

I guess you'd better pop out and find a 24 hour garage then

I have just checked and the battery charger is still flashing red/green, the charger is cold so I guess that's just the way it works.

I just did a search and found your thread, just charging my battery for the first time and my charger is doing the same as yours.

 

[Jimod]

Is it a kudos battery and charger? How long have you had it on charge for?

 

[Nigelk]

The battery was already charged 3/4 so I have had it on for 2 hours.

Once mine starts flashing green/red it normally goes solid green after about 30 minutes or so. I've never managed to time it.

Thank you for the feedback.
