Default Blade 400 Stock Charger Question and Problem....

Hey guys well I have a new blade 400 and I have been learning to hover it. The problem is that the batter is only lasting about 3 mins and each time I used it, it would reduce the time. So I just figured the battery was a dud. I have not even flown more then 3 mins yet so it could not have been over used.

Yesterday how ever I noticed the charge time my charger was doing was way to short. I would charge for about 3 mins then shuts off then starts up again then shows solid read lights meaning its ready. Well there is no way that its ready in 5 mins. I am thinking that the charger is bad but I dont know enough about these things yet. I was curious if anyone has had this problem before? I cant get a good charge for about a month so I am stuck with what I have now.

Again everything is what the kit came with for the B400. If I unplug and plug the battery back in it charges a little more then stops and it will keep doing it. Any advice would be great. Thanks!

Oh and I read about 11.4 volts right now across the three cells.

My girlfriend's Uncle bought a B400, and crashed it pretty bad, and asked me to put it back together for him. I said, "I'll DO IT THIS ONCE, but from then you, you have to rebuild if you want to fly".

Well, the B400 is a decent little bird, and flies really well. I put it all back together and installed some JR 287MG servos, and charged up his pack with my charger. I noticed his pack got really hot after flying and like you, only lasted about 3.5 min before seriously losing power. I told him to get new packs, and not get eflite packs. That pack was either damaged or low quality. It didn't puff or anything, but it's probably a fairly low C rate, and lower quality to be cheap enough to include in the RTF box. I definitely wasn't impressed. I've also fried my share of eflite chargers, I'm NOT a fan of their cheap little plastic box chargers. I'd scrap that thing as soon as you can afford.

If I were in your shoes, I'd get a new charger, you can get a little cellpro or a 3E for 40-50 bucks that'll be fine. There's all kinds of new units out right now that others can recommend. I did the small 3s charger thing, then after a year or so, I got a Logo which runs on 6s, and upgraded to the Thunder Power 1010C, which I freaking LOVE, and has worked like a CHAMP over the past couple of years. Honestly I'm so ignorant of the current charger marked because my TP charger/balancer combo has worked so well, I've never looked beyond it.

Optimally you want to find a charger you like that will tell you how many mah you're putting back in the pack, then you can base your flight timer on your mah calculations. After you upgrade that, buy some quality thunder power or outrage packs, or even some zippy/turnigys from flyhelirus.com and you should be a lot happier.

11.4 is low for a fully charged 3s pack, you want to see around 12.6 for all three cells.

Good luck, and have fun!

I had the EXACT same problem. In fact, it happened on two separate batteries. The Lipo that came with the RTF was an 11.1 3s 1800mah. Like you said, I would get about 3 mins flight then all of a sudden I felt the B400 lose power already. I called Horizon Hobby and they told me I had a bad Lipo. Then, they sent me a new one (the same exact battery). I had less than three 4mins 30sec flights on it till the same thing happened again! Now, here's the kicker. When the first battery died, I bought a new Parkzone battery (11.1v, 3s 2200mah) while I was waiting for the replacement. This green Lipo NEVER had any problems and I have probably cycled it atleast 20 times. I would fly the entire 4:30 consistently. I'm sure I could have gotten more but I didn't want to take any chances. The difference I see when I charge both types of Lipos in the same stock charger is that towards the end of the charging, in the green Parzone battery, the LEDs would actually fluctuate from GREEN-YELLOW-RED. Yellow means that the individual cells are being balanced. On the blue stock battery, it goes from GREEN straight to RED. I called Horizon Hobby again and told them my sob story and they offered to send me a 2100mah battery instead but from eflite not from Parkzone. I am still waiting for the second battery to arrive but in the mean time, I decided to go ahead and buy a better charger. I bought a Triton EQ from Tower Hobbies and got the EC3 leads and balancing board from the local hobby shop. I did not want to take any more chances and I did not want to overstay my welcome at Horizon Hobby.

Why not do what eabing did, phone up horizon hobby, chances are they'll replace it free of charge.

What are you using for a power supply for the charger?
