View Full Version : Newbie - 2 Q's Batteries & Parts
02-16-2010, 11:09 PM
1) I've read a lot of the posts on battery selection and there is a lot of good advice out there. For now, I am looking at sticking with NiMH batteries and will run them in parallel so that I have more run time (father/son bonding). Is this battery (I would buy two) a pretty good one for the 1/16 eRevo VXL?
Venom Racing 7.2v 3000 NiMH Stick Battery Pack w/TRA Plug - 1532T
eHobbies has it for about 28 bucks each, which may be a little steep, but I am looking for good run time. Let me know your thoughts.
2) I am assuming that I will be breaking parts in no time. The closest track is more than an hour and a half away, so I will mostly be driving on blacktop and grass, but will find ways to get serious air. What do you guys recommend as far as spare parts to have on hand. I know there is no way to know for sure, but would like to have some parts on hand so I don't have to wait 2-3 days each time I break something.
Thanks in advance for all your help!!!!!

Those batteries will not fit
You need a 2/3 sized cell pack and the largest capacity out there will be 1600 mah, stock traxxas pack is 1200 mah
2s 2200 mah lipos will cost you around $20 each

i dont think that one will fill inside. the biggest ive seen is a 1600 mah. might want to make sure it will fit b4 buying.
02-16-2010, 11:36 PM
oh yeah you might want to have front bumpers and skid plates
02-16-2010, 11:39 PM
yep, it won't fit. sorry.
Which NiMH 1600mah battery would you recommend?
02-16-2010, 11:49 PM
I've had a few of the so-called 1600 mah packs and none of them performed any better than the standard traxxas packs
My IB1600 cell packs ($25 ea) only took 1200 mah of charge and had small discharge wires
Others may have different experiences
Do you have a particular reason for not changing to lipo ?
A charger and 2 x 2s 2200 mah lipo packs should set you back lees than $100

The only reason I have been focusing on NiMH instead of Lipos is that since I am new to the RC world, and I didn't know if I should add an aparently difficult battery to the mix. Am I wrong about the level of difficulty associated with lipos?

they are really not that difficult.
Charged correctly, they arent any more dangerous than nimh. As long as you set your charge rate and capacities correctly, and have the balance plug connected, its pretty easy.
The problems come when people overcharge them, try to charge them when they have gone below the low voltage point, or charge them too fast, or do not balance them.

Slightly more technical in their handling but once you understand them they are a breeze
They provide longer runtimes and more power for the same size pack
I would just grab a second traxxas pack and run them in parallel until you get the hang of the truck
Then upgrade to lipos
02-17-2010, 12:16 AM
i am wanting to do the same thing you are doing
i want to stick with NiMH and i just what to know what battery and charger would be best for me
02-17-2010, 12:19 AM
Stock traxxas packs and any 50 watt ac/dc charger capable of charging nimhs
Stock charger works fine just takes 6 hours, good charger will take an hour or so
If you plan to go lipo at a later stage get a good charger now
02-17-2010, 12:25 AM
If you stick to nimh get this Battery
If you do go to lipos ********* is good if you can solder
If you can't solder
Get this charger, so when you say I should of got lipos like they said you will be ready :lol: JK kind of. Charges 2 lipos no problem $60 Delivered to your door
02-17-2010, 12:26 AM
Since I will be running with my son, 6 hrs/charge is not going to cut it. It would make the most sense to get a decent charger that also charges lipos. What do you recommend for lipos and a charger? Can I charge 2 lipos at the same time?
02-17-2010, 12:50 AM
I just went to the link you provided on the charger and they had a really good video on the basics of charging a LiPo battery. Very helpful. Thank you to all that responded to the battery question.
Any thoughts on the second part of my post? Spare parts?
02-17-2010, 01:12 AM
Axle carriers, A arms , pushrods and turnbuckles. Have not broken anything yet. I run in wide open dirt nothing soild to hit like curbs, light poles, trees etc.

Stick with nimh bats with either onyx 100 or onyx 240 charger the 100 with charge bats in about an hour, 240 will charge two at same time. get atleast two sets of bats for each of you. i have 8 total 4 series 1 powercells and 4 1500mah bought off ebay http://cgi.ebay.com/1500mah-RC-Battery-Two-2-Traxxas-1-16-E-Revo-Slash_W0QQitemZ400102614401QQcmdZViewItemQQptZRadi o_Control_Parts_Accessories?hash=item5d27f96581 the price is for two bats and they work great!!!!! BTW if you rmake one mistake with lipos they fry and some youtubes vids show the entire car melting....it was cool! i will NEVER go lipo, im not rich to have to replace whole merv.

Eddies , The videos on youtube show intentionally overcharged LiPo's. They are safe if you follow the Rules : Balance , Low voltage cutoff ( ~3.3 volts per cell ) , 1c charge unless specified other charge rate , and No charging of damaged packs. NiMH can also be dangerous if not taken care of. Try to Overcharge a NiMH or charge a damaged pack and you will end up with the same result than LiPo.

I saw a couple that were intentional, but there were a few were they were using the car and smoke stafted coming out of it and then the guy ran for the extinguisher by the time he got back the car was melted in half. lipo=fire (my opinion)
02-17-2010, 09:54 PM
Your opinion isn't very realistic. LiPo's are like anything else; if you treat them right they don't have problems. If you abuse them, they'll break.

anyway..........I would rather spend time having fun with the rc's with my son then having worry about my son or myself accidentally destroying the cars...It's about bonding not bashing
