Re: Buying LiPo's cheap in Canada Here is the Dynatron Starter with the two 3S lipos in series. The tray also holds the two glo drivers one short one long, a plug wrench and spare plugs. The black box on the back with a push button is 12 volt power supply for an electric fuel pump. I also make these aluminium caps for the fuel jugs because I got tired of fuel going bad when left on the shelf. A Viton o-ring seals the bottle. Most of the time my glo require just the starter/batteries, the fuel jug/electric fuel pump and I'm good for the day. It doesn't get much simpler than that. Oh with the 22 volts the starter will do the 50cc and under gas. Dennis |

Re: Buying LiPo's cheap in Canada quote: I don’t use them for flight packs any more haven’t for a couple of years but they still take a full charge and run the expected amount. ..... Aha!  I use very old Zippy's also but I use them to turn over a 12 volt torque starter on my glow and also as a source for the glow starter when I fly without onboard glow!

Re: Buying LiPo's cheap in Canada Quote:
If my packs are not to be used on a regular basis I do keep them at the recommended storage charge. My shop is heated and air conditioned so the batteries never experience extreme temperatures. Yes it may be time to get rid of them but me being a tightwad I hate to get rid of something that still is working. I don’t use them for flight packs any more haven’t for a couple of years but they still take a full charge and run the expected amount. There are just lighter more powerful options available. Yep out of all the Hobbyking stuff I found the Rhino and A-Spec the best of the bunch but take a look at the last picture you will note the gassing of those two compared to the Pulse on the right. All three flown in the same two airframes with the same motor/esc combo. Dennis |

Re: Buying LiPo's cheap in Canada Anyone who has lipos from 12 years ago should write a book about it. There aren't too many of those hanging around anymore. I have rhino batteries from about 5 years ago that pound the crap out of outrage batteries. |

Re: Buying LiPo's cheap in Canada Understand everyone’s battery needs will be different. If the power system you are flying has a low draw in the indoor/foamy/parkflyer class and you do not change anything the recommended batteries will work well for you. As soon as you start changing things your batteries may end up being the weak link. A parkzone setup recommending their 3S 2200 pack and the recommended charger is a good match but as soon as you decide to put a more powerful motor many times the esc starts to give you issues so that is upgraded. Not many at this stage give the batteries much notice but now the draw may be too much and they puff/fail. Plug and play systems are great but most end up wanting more. When you do that you need to build a balanced system matching the motor/esc and battery. This is where many fail. Like most of you I like to support my local hobby shop and since there is none in my immediate area that stocks the supplies I require mine is in the US which is 20 minutes away. I try the batteries/equipment he carries in stock. He carries Flightpower but the availability I needed was sporadic. He recommended I give these new ones he was stocking (Pulse) a try. The Heli guys were raving about them. I know they put a work load on their batteries so I gave them a try and have come away with a very positive opinion of them. Not inexpensive but reasonable for my needs. As to who makes the cells it’s like who actually makes the motors we use who can say for sure. If a certain brand works for you then it’s the right choice for you no mater what the cost. Cheap or expensive if it leaves you wanting it’s not any fun. When I go to the field I want as few hassles as possible so cost is but a small factor in the fun quotient. Anyone been riding motorcycles for a long time? Remember the emergency tool kit? Yes it had the necessary emergency tools but how did they work? Better to make your own tool kit up with brand name tools, spend a little more but when you need them you can depend on them to do the job. Dennis |

Re: Buying LiPo's cheap in Canada Quote:
The biggest batteries that I use now that I got out of land RC all together are 3s 2200mah. I have only had a few brands...all of them budget brands except Parkzone. The funny thing is that I've puffed 3 of the very expensive Parkzone lipos but none of the budget ones. I'm also very careful with my lipos...never over discharged, low charge rates, etc. That said, I'm not in any way disputing your findings, just saying that you don't always get what you pay for. I believe the Parkzone and a lot of the other pricier lipos are just re-branded budget brands. I do believe there are some really good lipos out there...like you said Thunderpower, and I bet other premium brands like Flightpower are good as well. Since we are on the topic, I believe the Revolectrix batteries are reasonably priced and supposed to be of good quality. I keep thinking that I will try them next but like I said my current stock of lipos just keep going flawlessly! |

Re: Buying LiPo's cheap in Canada You can say all you like but if I had used a Canadian supplier - just a transaction,,however,,picking up stuff from private sales and yes a few HK LIPO's on a trip to US a few days ago..sitting in Alki Park in Seattle watching the ferries etc. and getting a tan, then walking around Washington Park Arboretum and looking at all the cherry blossoms, and green grass..Oh and did I say getting a tan 18-20 deg C and the sun WAS shiningExcellent hotel 71.25 US a night with free excellent breakfast and newspaper and.... but hey I could visit Winnipeg for $130 CDN a night. Gas $2.56 US a gal.(3.78 litres) Sometimes it's not about the money. |

Re: Buying LiPo's cheap in Canada Now let’s be clear no one in our club pushes the batteries as hard as I do so less expensive batteries may fill the bill for them. I do know one thing I constantly hear complaints about puffing and failing to take a charge or balance. I know many have had issues with their batteries and from my observations most are related to Hobby King batteries/chargers probably because these are the ones most common at the field. Many of the batteries I observe in use show some gassing or puffing usually greater just after charging but will go down if they sit for a bit. |
