SV27 - going lipo - what connectors are needed?

[MLJones8]

Hey all, my name is Mitch and I just purchased my first rc boat (supervee 27 electric w/ deans). I've been doing research on many forums/sites for about a month now and I plan to just start out with lipos. The sv hasn't arrived in the mail yet, and I haven't purchased the batteries but I have a few questions.

- I plan to run the stock motor/esc so I'll need to purchase a LVC.
- My choice of power is going to be:
(2) Flightmax 2s1p 5800 mAH wired in series = 4s1p, 14.8v, 5800 mAH (@ 100a)



Now some questions... (keep in mind my sv has deans and stock parts):

The Flightmaxx 2s1p's have 3 pin balance plugs and bullet connectors (these are not used during a run correct? i.e. only during charging), what all connectors do I need to run w/ the LVC and in series?


So if I...
- Purchase the LVC w/o dean connectors:
Do I simply...
1. cut off each dean connector on my boat and
2. solder two positive wires together & positive from LVC
3. solder two negatives together & negative from LVC
4. solder the 3 negative sides to the - post
5. solder the 3 positive sides to the + post

This means I would need 3 dean connectors?
- One MALE for the 6 wires from the ESC/LVC
- (2) FEMALES one for each battery
- and the series adapter pictured blow?


Last question:

- After we have decided which connectors are all necessary and exactly how to wire it.... Should I just change the plugs on the boat to bullet? instead of soldering on dean plugs for everything?
- I think the batteries come w/ bullet connectors
---Thus all I need is 4 bullet connectors & some extra wire to make a series adapter?


Thanks!

Wires

Cut a small section of insulation from the red and black wires on the ESC and solder the LVC to each then use a little silicon sealer to seal up the wires as for the bullets you don't need any adapters just new ones for the ESC.

wizard,

Thanks for the reply... My sv27 is still in the mail (so I can't look), but isn't there 2 red/2 black wires coming from the stock ESC? If so I'm unable to do it your way... correct?

No you eliminate the deans connectors and jump the two packs so theres no jumper in the ESC harnness together look closely at the photos

Ok I think I understand now... I'll have to just wait for all the equipment to arrive to be sure.


One last question: I'm assuming one of your batteries has a male negative lead (thus enabling you to run them in series as pictured)???

- How do you charge it? A home made connection?

Bullet connectors

Cool use these http://www.offshoreelectrics.com/pro...d=ose-55bullet
Did you buy your batteries and charger yet? I would suggest these its what I use and work great and you don't need to change the connectors

http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=10305&Product_Name=Turnigy_5000mAh_2S_40C_Lipo_Pack

and this charger

http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=10305&Product_Name=Turnigy_5000mAh_2S_40C_Lipo_Pack

or this one this is the one I use myself

http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=7523&Product_Name=Turnigy_Accucel-8_150W_7A_Balancer/Charger

you will need this power supply also

http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=6879&Product_Name=16A_14v_DC_Power_Supply_for_Chargers

I can charge up to 2 packs at a time with no problems if you get a cheap charger it will take forever to charge your batteries plus spend alittle more now and you will save money in the long run good luck check out my post's for photos they will help with set up also you need to seal up the hull for leaks and Z-poxy all the wood don't forget.

You posted links to the same battery twice instead of the charger

Great thanks for all the info! I placed an order for the flightmaxx 5800 lipo's but once I got to shipping (air mail 6-31 days). I canceled to research if that was the true shipping time to the US or I I should pay the extra cash to get faster shipping. If I switch to the batteries you suggested I'll save $12 and get a higher C rating, but loose 800 mAH.... Would you suggest doing so?

As far as the charges go I'm thinking I might go with the Thunder AC6 (but won't be able to charge two 2s lipos at the same time (well I could, but at a very slow rate).

The 5000 work great not sure about that charger send me a link the ones I suggested can be used at home and at the pond if you buy a good one now you will have it for years I can even charge 4 packs if I want to but prefer to only charge 2 at a time. Found that charger I have one like that too only 50w will take a long time to charge big packs try to find something with about 150-250 watts 4packs charger and power supply from HobbyKing 275.00 shipped 1-2weeks thats the best you'll find I think good luck

I was under the impression that the 50w AC6 knockoff charger would charge each 2s 5000 mah lipo in under 90mins, so less than 3 hours total. Yes that seems like a long time; but since I'm just entering the hobby I think I can make due until I can justify the extra $200 for a better charger. After all for an extra $200 I could buy a lot more juice :)

Packs and Charger

I think you misunderstood me. The $275.00 shipped is for 4 5000 40c Turnigy lipo packs,8c 150watt Turnigy charger,and 15amp power supply. I can charge 2 packs in about an hour

Understood, so w/ your 50w charger you run your batteries in parallel and are able to charge them in an hour? Or w/ the 150w your able to do this?

150 watt

With my 150 heres a Photo of my set up

[wizard122]
