| Couple Questions about Lipo's
I'm getting a new mini boat, and the only packs i can use in it are Lipo(because of the weight). The company recommends a 3 cell pack. And from there I'm lost, with the C, burst, etc. I will be running this motor, a 400 Df outrunner(2600 KV 18 amps continuous) with a Castle Phoenix 25 esc(this combo will make it a 50+mph boat). So i need a lipo pack and charger but dont want to spend an arm and a leg on it. Can anyone help me out. Or does anyone have any ideas on regular cells that are small and light http://www.castlecreations.com/products/phoenix-25.html Last edited by '83 chevy; 07-31-2007 at 08:37 AM. |

those are not bad batteries. i run them in my 1/18 scale stuff. they hold a good charge and have alot of high output. just like any lipo. what price range are you wanting to spend on a charger. and keep in mind these things can blow up if not taken care of.

I would recommend a charger that balances too. Are you ok with waiting 3 hours for a charge, or would you want something faster?

ahh yes, that would explain the seperate charging plug that is only two wires. What is your budget for a lipo charger? $60, $30?

I already have a Peak charger i use for my other boat packs, and car packs. Maybe I can sell that and put the money towards a multiuse charger. Might either go with this http://www2.towerhobbies.com/cgi-bin...?&I=LXMRH8&P=0 or this http://holmeshobbies.com/product.php...9&cat=7&page=1 Last edited by '83 chevy; 08-01-2007 at 04:03 PM. |

Any of the chargers mentioned would work well and be easy to use too. I actually have one of the 535 thunder power chargers now and they are pretty awesome for the size. Just three buttons for everything, but they only charge lipo.

| x2 on the duratrax ice charger. i use it to charge lipo heli packs, li-ion nitro heli rx packs as well as nimh tx packs. best all in one charger IMO, and they can be found on flebay in your price range.

I would recommend against the triton, and go with any of the other 4 button chargers or the triton jr. instead. I found that the scroll wheel played out and got hard to use over time on the triton, making it very hard to dial in the correct parameters. On top of that the wheel is also the select/enter button, so it gets even more use.

The maximum discharge of the pack is 18.75 amps, the motor only draws between 12-15amps depending on the prop. And the Esc can deliver 25 amps.
