Decent Portable Generator for Field-Charging

[del19_82]

Kipor are hit and miss,i have the clarke one and its crap also.....honda next for me should of listened to my mate and got one from the off!

My Honda 10i has started mis-firing. It was perfect for a year or so and then started running quite poor, it's got to be run at half choke or it cuts out. It's been back to Honda & their response was that they do go and that there isn't much that can be done for it .

try cleaning the carb
as it sounds like the jets are blocked similar to my dads 25 year old honda one

Give it to Matt to get serviced del..

whats the Honda UK warranty on generators..? I might try and sell a Kidney

[barney]

seems the warranties vary..up to 5 years which sounds great. I wonder if there are loopholes though?

try this little generator

Nah, these, then we could have one at each club

We got one of these nuclear jobs at our club. Charges a 5000mah pack quite fast, I can get away with about 10C

I get 6 x charges(5000mah lipo's) off a 100 amp leisure....is your 70 made by Carlsberg?

How low is the volts from the battery when the charger cuts out. Some chargers will only go down to 11V, others will work to 10v. You need thick cables to avoid dropping too many volts at 12v.

I got a Kipor IG2000 from KMS (see Dashiks's thread) It ran great but the inverter board failed last week. The Kipor is just a shade over 6 months old with about 4 or 5 gallons through it. Its never been near its output limit, running only a couple HP server supplies and 2 x 300w I-Chargers

Now something like this I would expect several years in domestic use + I thought our consumer rights would have given me cover for at least a year...not according to KMS.

You can ask him for more detail on their overload warning light and exactly what the detector circuit is measuring. A generator should not fail if it is overloaded. The instruction manual even says that an overload does not kill the generator but might shorten its life. I assume that you weren't getting the overload light on before it failed completely, and that you always plugged in the chargers after the generator was up to speed as it says in the manual. It sounds like an infant mortality to me. Ask for contact info from the company and go to them. Every thing sold should be fit for purpose. If it is not you can claim a refund. He has no evidence that you have overloaded it.

If you are going to charge lipos from your car battery make sure you run the engine between charges, unlike leisure , car batteries are not designed for deep discharge and will be damaged very easily.
The main problem with using leisure bats for field charging is that as pointed out above, the lipo charger will cut out when the voltage drops below around 10.5V, I have a 140 Mah leisure battery and I managed to charge a 4500 mah 12s lipo 2.5 times before cutout. Then I bought the Honda, very quiet, very efficient, very expensive,

[cjcj1949]

On my charger the cut off voltage is variable and will go down to 10V. The damage to a lead acid battery due to deep discharge takes a while to happen and I don't think a few hours would be a problem. I would run the engine while charging if possible as that will keep the battery at 14V which will be better for the battery and also keep the volts up for the charger.
Lead acids do have a big swing from being charged, up to 14V if full down to less than 12V at 10's of amps down to 8V or so at 200amps. It may be an idea, especially for people doing high current charge and discharge to use the old lipos that are not good enough to fly as charging batteries.

This problem is going to get worse as lipos get better and can be charged quicker. I'm not sure generators are a longterm solution. Buying more flight batteries will work, as will mains electricity and on site storage batteries. Chargers that work to a lower voltage would help as well, or charging at 24V or 240V.

I know it's boring, but 240v and moisture can be a problem. I'd like to know what people think of having floating supplies or having earthed supples with rcbs. Is there a safety device that will work on a floating system?

Thats a very good warning from modelguard, as one of our flyers was using the car battery on his two year old BMW to recharge his packs and although the low input voltage alarm on his charger had not operated, when he came to start the car later the battery was dead. The AA man was called and he declared the battery totally defunct,so the car was towed and away and the flyer ended up having to buy a new (and very expensive!) battery.

I use three Yuasa NP12-17Ah deep cycle standby batteries for field charging that came from a 110V central battery unit that was being scrapped at our local leisure centre. The engineer was more than happy to give me all eight batteries and despite being 5 years old they still perform like new, so I gave the other 7 batteries to club members.

These batteries offer a much safer and almost worry free option for recharging away from home, providing you remember to charge them up before you go to the field of course!!

I think that means that the BMW had a dodgy battery. I've had batteries that had very low capacity(2AH), that would start a car but wouldn't after I had the radio on for 30mins. You can't rely on your car car battery being able to start your car at the best of times, if you are not sure then don't do it. If your car doesn't start after using it to charge your lipos then charge it up using your lipos and the lead acid program on your charger. I wouldn't use an AA man or any other mobile battery man as they are a good way to ruin batteries and the car electronics as they use very high charge currents that will finish off a car battery and some of these fast charge setups don't limit the charge volts and have caused car electronics to fail due to being overvolted. I've recovered batteries that others have said were dead. Sulphation can be reversed. Everybody who uses car batteries for field charging leaves them discharged for a few hours without problems.

I'm going to get our clubs resident engineer (AJM) to have a look at it and see if he can find anything, like i said, its been back to Honda & we had no joy with them finding a fault on it
