X-peak 3 problem?
 

I thought I had this charger thing figured out but I guess not. I have a 5S2P 8000 mah pack that I'm charging with the X-peak 3. I know this charger will only charge to 5 amps but it should still charge the entire pack just slower, right? Well I had suspisions about it the past two flights when the charger put exactly 5500 mah in the pack before shutting off. Well for the first time today I flew until the voltage cut off and the charger still only says it put in 5500 mah. Am I going to be forced to have someone seperate the pack for me or is the pack indeed fully charged? Today I flew for over 45 minutes. It took just over 90 min to charge the pack back up. Please help.

I had similar problems with another similar charger. Here is what I found.

1. The charger timed out, it took too long to finish.
2. Not enough voltage was input into the charger. I could not do it from a 12 volt car battery, I had to buy a powersupply that put out 13.5 volts.
3. I think your charger is a UK item, you might contact them.

I probably didn't help, but, what the heck, I tried.

MIke:

Did you ever think about this. Input to the charger is 12 volts, output to the Lipo pack 15 volts. That means the charger has to have a transformer inside. When it boosts 12 volts up to 15, it looses amps. Not enough amps or volts and your battery will not fully charge. Don't forget, as Lipos get charged, they actually resist the charge more. It's like the charger has to force the volts into them. When they report back to the charger that the voltage is dropping off, the smart charger stops to avoid an overcharge. Something is fooling your charger or the charger is underated and really can't handle 5S at your amps. It could also be that it's made in the UK and paying you back for the US independance. LOL

Found to solution on another board. I figured I would post here for the info.

Hi Mike,

You have proberbly the X-peak3 plus.
This one loads in capacity. So it stops after 5000mAh +10% = 5500mAh

You need to restart the X-peak3 plus, to get your 8000 mAh pack filled.

Ps. the older X-peak3 did fill with amps. So it loaded until the batterty was full
