Voltz 4000mah Hard Case 3S 11.1V 50C LiPo - Deans

No, this will be too big for that chassis.

This is the battery we would advise in that car: VZ0341

4A would be our standard charge rate on these (1C)

It should be fine yes - just be aware this has a deans connector and you'll likely want EC5

Yes that should do

yes should do as they use velcro straps

I think VZ0341 would be a better fit in that

If it's the VXL model then yes that would physically fit, however the connectors will be wrong

Something like ET0225 would do the job

Or ET0202 would be a better spec

Afraid we don't sell that car (it's not one I've heard of...!) so we couldn't advise sorry!

Charger though - something like say RDNA0465 or ET0202 would be ideal

Constatn

No it's too tall.

You could look at say VZ0341

Standard XH balance plugs on these

No I think it'll be too large sorry

It should physically fit (the wires might be a bit tight coming out the top of the pack) - however as you point out, the connectors are wrong.

You'd be better using the Traxxas 3S packs such as TRX2872X or TRX2849X

No, your ESC should provide a "BEC" voltage to the receiver of around 6v, so your servos will be fine.

Correct, we'd charge at 4 Amps on these.

We're not 100% sure... we'd stick with the recommended  HLNB0039 - it's 3S 3600 so slightly higher capacity and is a drop in fit.
