Just received my order from Promatch yesterday. Great pricing @$89.99 per pack, free shipping on orders over $100.00. They came shipped with about 3000mah charge in them, discharged them down to 6 volts, then charged them back up @ 5 amps on my turbo 35 gfx, both packs took over 5200 mah of charge...can't wait to use them this weekend...almost blew the tires off the rims on my dirt buggy. Just wondered if any one has used them and how they are doing compared to other lipos out there

Thanks,
Bill Luongo

I haven't compared them to other LiPos but when I ran one in a Slash, it was faster than with a 7-cell pack of 3300s.

I could have sworn that I clicked on the 'electric on-road' forum...

so i guess the guys from smc and from ultimate hobbies shouldn't be posting there either ...just figured i'd get a response in this forum...and lipo batts are used in electric onroad

I've only use three lipos so far, TrakPower 4900 Gold, Trinity 4500, and the Pro-Match 5000.

Using my DPD dis-charger and the external plug I dis-charge all three battery types once a month and record the numbers for comparison.

To date the Pro-Match battery is my best. 30A dis-charge Rt-577, Vltg-7.33v These numbers are about 100 seconds and .1V higher then my best TrakPower. Based on my comparison so far I would highly recommend the Pro-Match. In fact I plan on buying a few more myself.

I have not used the SMC 28C battery yet but I have a feeling it will also be one of the best in the market. My problem with this battery is the wire placement. in fact I wash all Lipo vendors would use the 4mm banana jacks like Orion and TrakPower.

I hope not. If that happens, someone in a rush to plug in their battery might plug them in wrong and end up blowing their ESC's.

I'd rather have the option of putting on deans and having one less failure point to deal with.

i agree with sabin...one of the reasons i avoided the orion was those silly banana plugs....i saw 4 guys plug them in wrong in a matter of a couple of weeks...burnt speedos...shorted battery....one of them caught on fire...not for me. deans pretty much make it idiot proof...i am capable of idiocy

Me and a buddy have 1/8th scale electric conversions and are running the SMC 28C LiPos (because they came out first when we needed packs for the 1/8th scales). I sure wouldn't want my Neu motor, capable of drawing 100+ amps, trying to pull that current through a 4MM banana plug.

And on to the subject: The ProMatch LiPo. My car isn't set up with Deans but my buddy's is. We were out practicing yesterday with our 1/8th scales. Since I still have the Deans on my ProMatch packs I let him run them for a while. He said there was no difference he could feel between the ProMatch 25C and the SMC 28C. This is a Neu 1512 2.5/D/F in a 1/8th scale buggy.

thanks taman...i kinda thought that might be the case since promatch and smc nimhs were pretty close in performance....took the chance on the promatch for the price difference right now...just made the switch to lipo brushless in three cars.

If you're worried about idiocy (no offense intended), you could always make a banana plug/wire/deans connector and just leave it in there and use it like every other battery pack...

I fail to see the big difference between deans and banana plugs.

In a rush, banana plugs can be plugged into the wrong polarity since they're the same . Deans can't.

Ive seen this happen Bye, Bye Speedo and your underpants

Logika

They could make banana plug diffrent on one polarity for example plus is 3.5mm and negative is 4 mm you would never stick that 4 mm in 3.5mm.

Again I fail to see how thats any different than direct soldering. Plus my wires only reach the right spot.
