TrakPower lipos for Off Road?

[tiny tom]

I am thinking of buying trakpower 3200 (20c) 2s 7.4v saddle pack, which I am going to use to race at club level. As anyone used this in off road racing? I am going to use it in a pred x10
And does anyone know when the brca are going to allow them to be used?

What motor esc setup are you going to be using with these? Because 3200 mah at 20C, means you can only get a max 64 amps out of those batteries which is not a lot for some of the very fast modified motors out there today. Using a very fast motor will probably cause the batteries to heat up considerably, not to mention they might not give you enough current to power the motor properly (thus reducing performance). Lipos are quite an investment and you don't want to be re-investing just because you don't get enough power for your racing needs.

Just as a comparison, I ran (for the first time) my B44 with 5500 mah Lipos (15C) and a Mamba max 6900 kv motor. The motor is very powerfull, but the batteries were delivering plenty of power and satyed nice and cool. Some others at the track were running smaller packs (2500-3000 mah) and they were getting very hot (some even swelling!). Not good.

Anyways, it's just food for thought! Buying a bigger Lipo not only gives you longer run times, but more power to the motor.

Hope this helps!

Well I am going to run the losi brushless speedo and 5.5 or 6.5 motor, but after speaking to trakpower they said that they don't really over heat. And they think that 3200 would be enough to do the race, and only needed 2 packs.

i ran 3200 in my d4 with a 5.5 and they were spot on. chris long has been finding the 3200 pack plenty good enough and up to the job, and he is a far better/fastr driver than me

you wont have any problems with the trac power 3200 lipos 20c we run these cells with 6.5 in our tcs and have no problems but if you wait no dought trac power will realse the new 3600 30c version in a saddle pack configuration.

I have run the 3200 trakpower saddles in several 1/10th off road cars. 2wd and 4wd. In 4wd I was using an Atomised B44 running a Novak 5.5R, I ran 7.5 minutes of absolute flat out driving on a large grass track and they had 10% left in them.

IMHO the performance of the 3200 Trakpower is almost identical to my top spec Slingshot 4500 packs, both in power and duration.

Just don't forget to set the Lipo cutoff on the speedo. If you discharge them past 6 volts they will almost definately be terminally damaged.

Confirmed. You'll find 3200 20C saddle plenty for any buggy, any motor. They are as good as the best 6 cell nimh pack on first charge, but the Lipo (providing you follow the guidelines) will continue to be this good for, well, for ages - mine haven't dropped off yet and to be honest, ive abused them as hard as possible without doing anything obviously wrong.

Don't forget these are 20C, this means 64amps continuous. The Peak ampage will be more when demanded.

If you are going to anything more, such as 4900's, then you will need to motor down otherwise it won't be controllable.

Oh, and nobody can say that the BRCA will be allowing them. If they did it'd be an utter gamble to say now.

All I can say is proposals to the BRCA will be made, and to get them accepted then please do attend the AGM and show your vote. I will be. The rules are proposed and voted on by the members for the members, "Yes, this is you!" (26th October) www.brca.org
