hi all, being new to rc car cells i am finding a few things perplexing, the biggest of all being weight (mass) of lipo batteries.
I am trying as hard as i can to keep weight down on my Typhon build and found a battery which gives me C rating, mah and the weight range in 4s, so all great there apart from the fact i cant find stock of these batteries in Australia all out everywhere on Performna racing 5500mah Hv 25.2v and 120 c shorty fitting the typhon tray so sweet as bro.
I have noted the effect of c rating on batteries and seems consitant with weight of the battery as does the increase in mah, naturally.
Now i am trying to find a HV 6s battery and things in 6s just do not add up, unfortunately Performa racing do not make 3s or 6s, so that just plain sucks as they hit my target spot on with 4s.
I was looking at 6s from spammers, the new advanced batteries, but holy hell seriously $300 Aud battery plus postage, dimensions are out of control on a 6800 cell and weight, like really are we strapping in nearly 1 kg just to run 6s?
To my mind weight is a major player, the Performa 4s is only 410g, @ 5500mah 120c, more than double the weight for 6s is just plain stupid, weight means available power,torque to the wheels, less load on drivetrain and motor and less current draw through the esc to move a heavier load.
Math is telling me i should be able to find around 6000mah 100c HV battery that weighs in at around 600-700grams, why are we pushing 1kg batteries around and paying a small fortune for them, i can buy a Castle 1717 for only $70 Aud more than supposedly the most advanced Battery going.

The only available cell that comes in around $200 shipped that even comes close is the SMC
https://www.coast2coastrc.com.au/sm...-v2-22-2v-5200mah-120c-hardcase-traxxas-plug/
Is the above SMC the best we can do so far as performance and weight goes?? Please advise your best recommendation.
I have no problem paying for quality as with many things we get what we pay for. For some reason i don't like wires and balance leads hanging out of my cell, don't ask me why maybe in the year 2022 i simply expect better.
Am looking into 6s for the Typhon build, has anyone run a centre locked diff? such as below and what were your findings versus open centre or open with earplugs?

Has anyone found it necessary to run a heavier motor mount on 6s?
I am not looking into serious speed running just yet but the 1717 is on the cards at some point in the future, maybe limitless?? will see what the TLR can do as a test chassis first.
aprreciate some pointers from the folks who have the experience and willing to pass along.
