Questions?? brushless w/NiMH batteries?

Can you still run a brushless motor with the batteries that you use with brushed motor w/ the long run times that a brushless would normally run?
(im running a havok 1/10 spec brushless system 17.5t). Will i lose some power w/o lipo if its possible?

Been running brushless with NiMh in 1/12 scale 4 cell NiMh for two years now. Works great!

Not in 1/12 scale. In 1/10 off road I ran NiMh with brushless in 2008. In 2009 I made the switch to LiPo in 1/10 off road.

Me too. But 6-cell. I've been running nothing but NiMH since I'm waiting for my packs to die off before I plunge into LiPo.

So far, my NiMH has been super strong and hassle-free...

I run four packs of 3 cell + 3 cell NiMH saddle configuration for my B44, four packs of side-by-side 6-cell NiMH for the rest of my vehicles. Brushless systems I have are:

Mamba Max + 5700Kv

2nd Mamba Max + 4600Kv

Ezrun 60A V2 + 4300Kv


When I initially dove into the brushless system, I did have a fall out of a pack. It made my systems cog, so I found out that pack was really weak.

It's the odd-ball "Sanyo" Team Orion matched pack. I think it had a bad cell in there that couldn't handle the sourcing.

Rest of the packs, they're no prize winners either, they are 4 to 5 year old 3300 to 3600 mAH NiMH, most are GP-based cells (I think GP cells are the best NiMH out there, reliable and trustworthy). But they run strong though...

Wait til ya throw a Thunder Power 40c 5400 saddle in the B44. WOW! Best part is you can race 3 qualifiers and the main with just ONE pack. Just top it off after the 2nd round and it's all good.

So the NiMh still gave you a good brushless run time?

NiNh will do you fine, but for time It'll give you minutes depending you driving style. Lipos will give up to 20minutes depending on driving style. Lipo has better Accelleration and punch when you need it. May have to purchase a lipo charger, It does take a little more time to charge, but lipo you can charge them anytime. Just maintain them correctly. Learn more about lipo on the web. You'll find which one is best for you. NiMh's the past, lipo's the future.

Cheap NiMH packs will have more punch in stock then cheap Lipo packs as a rule.

We've been using brushless with NiMH for about 7 years now.

The advantage of Lipo over NiMH is weight and steady voltage. They weigh about a 1/3 less than an equivalent NiMH pack and the voltage is as strong at the end of six minutes as the start.

With 1/12 scale the trend is 1S 3.7V Lipo packs where you will need either a booster or a Rx pack to power the Rx and servo. With today's Lipo making 8 minutes is no problem and the voltage is steady.
