Looking at getting a RC Tamiya buggy

http://www.modelsport.co.uk/tamiya-dark-impact/rc-...

and don't really know which or how many battery packs to get - 2200, 3300, 4000, 4500? I'm going to keep it standard to start off with, but potentially upgrade the motor when I get used to it. Not thinking of racing it - just hacking round the back garden and a mate's old quarry.

Was thinking about getting two 3300 packs on no more basis that it was sort of in the middle! Last had an RC model 25 years ago and I'm thinking battery technology's moved on a bit since then!

Battery technology has moved along as I found out recently when I got back into battery RC. If you have a decent fast charger then go bigger capacity, but stop where the price goes up out of proportion. Get 2 or 3 and that'll probably do for most of us.

I was in the same boat as you.

It has been described to me in boxing terms, that voltage = how hard the punch is, and capacity = stamina, how long you can keep it going on for.

I have 3300 Nimh packs on most of mine, mainly because they're reasonably priced, but also the bigger the capacity, the longer it'll take to use up the battery, but also thelonger it takes to charge. A 3300 battery probably takes about 40 minutes to charge. If you get bigger you'll be charging forever, arguably better to have a couple of 3300's.

I went bashing with my son at the weekend using the twin motor Tamiya Dual Hunters and 2 batteries was more than enough for us to have great fun with.

I decided to invest in a decent charger, Lipro 6 Quad which charges 4 batteries at once, all digital and can also charge Nicd and Li-po. It cost me £170 but the Nimh need a bit more attention charging than other batteries in so far as they need cycling and draining fully before charging. They don't like being topped up. My nephew who doesn't use his much had a knackered Nimh and this charger brought it back to life after a couple of disharge/recharge cycles. Well worth the money imho!

Good luck,
Cheers

Cheers for info.

Went with 3 x 4000 packs in the end as the quarry is a good 20 min walk from the road and I'm not carrying a car battery and a charger for that long! Hopefully a stock motor should last an age on a 4000. Hopefully car should last 3 loooong sessions!

Went with cheapy charger in combo deal. If I get into it properley again and (critically) manage to persuade mates I'll upgrade to one you suggested.
