I have two old SMD/Mugen style boxes(2x motors..) I have always used two nimh stickpacks, but was wondering how to use a lipo with them. Could I just use XT60 to Tamiya plug adapters? What size lipo - 3S or 4S? Or 2S per plug since a normal stick pack is like 7.2V?

I don't want to have to solder or rewire or otherwise do a bunch of fiddling. But if I could just buy an adapter and use lipos I already have (lots of 4S and 3S...) I'd consider it, instead of buying more stick packs.

Thanks.

Edit - OK, I see I was right.. It'd have to be 2x 2S...

I guess if to use a 4S I just have to solder one or two wires I'd do it.. I have a ton of 4S lipos...(planes and quads etc..) But don't have any 2S, except very small for micro quads..

You can use I 3 cell lipo. with a much larger amp load connector..Make a jumper for the battery you connect closer to the + side of motors.. xt60 and Tamiya are not that great .in my mind.

Herrsavage

All my lipos are XT60...(except a couple car lipos with Deans...)

No clue how to make a jumper...

the rc guy

OK to make a jumper take a male plug or what ever plug comes from your battery and hooks up to your starter box...take a short piece of 12 ga wire brae both ends and bare them.then tin them add 2 small pieces of heat shrink tube now solder them from + connector pole to - connector pole. wait a few and slide heat shrink over connector and solder joint.. connector or jumper made. put on starter box now your ready to connect a lipo to get your nitro up n running.ill try to add pic later

the rc guy

on a deans plug it will be the female on Tamiya im not sure but its what ever plug goes from battery ti starter box wires. sorry dont have a jumper and not walking out to pole barn to find 1

Don't think I've got any 12awg wire laying around, but I do have some XT60s which came with wires attached, so I assume 12awg. Anyway, I was just searching and couldn't find any clear pics about how to do it. If it really just takes soldering a simple wire I should be able to do it.. I'm a nitro and nimh guy ha ha... And even though I've been flying (mostly PNP) planes and quads for a while, electronics is not really my thing..

So yeah, some pics would be appreciated. Thanks..


Edit - So, looking at this pic, I just remove the one-to-two connector, and solder on an XT60 where the one Tamiya plug is, or? So basically just removing the series adapter and changing the plug?

Herrsavage

Ok, got it... Snip off the Tamiya plug and solder in the XT60. I tested it with an adapter and it worked. I assume a Tamiya plug can't handle 4S though... Or can it?

the rc guy

no to handle 4 cell lipo its the amps is all.. and yes to solder xt69 in Tamiya plugs place..

Starter Box: 4S Lipo + Tamiya connector ok?

I bet Tamiya would work - for a starter box that isn't being run for long periods at high power..

Still, I'd have to order a connecter, but I have the XT60 right there. I really am not fond of soldering though... Oh well, guess I have to.. I am thankful that it will save me from having to buy more stick packs..(mine are all like 10 years old - or older...)

the rc guy

do what you want its all yours even if it goes up in flames..

Just replace the Tamiya connector with a Deans (or XT60, it will work as well) with the wiring as in your picture. Even if you hate soldering, do it once properly and you're done with it. When I began with nitro I left the Tamiya and eventually they started smoking and melting - unpleasant to see.

Don't use the adapters, with a single connector you can use both a single 4S pack or 2x2S hardcase packs (in this case you need an opposite Deans or XT60 with bullet plugs on one pair of +/- from different packs, and a jumper cable to connect the other opposite +/-, just as you would to power an ebuggy).

the tamiya connectors struggle in these applications because of load draw, especially when a engine is tight/cold.

they are OK for anything made and manf back in the 80s-90-00 but certainly not now - i believe they should not come on starter box's, guess it might depend on the factory, some box's come with deans now.

I converted the Ofna blue box to single Deans plug. Well, I say I converted it but in actuality the previous owner robbed the plug wiring off it. In any case, I bought the Reedy lipo 4S pack that's intended for starter boxes, and was surprised when it showed up because it's about the size of a pack of vending machine peanut butter crackers. Cranks my .21 Novarossi engines all day with no problems though.

I'm going to solder on an XT60. I have tons of 4S lipos, from 1500-3700.. I'll probably connect 2x 1300 4s quad lipos for 2600mah, since I haven't been flying quads much.. I'll just put some velcro in there. Plus I have a parallel adapter.. So just one snip and solder job, and I should be good to go.
