Newb battery and charger advice
Just got a Slash 4x4 and need a battery and charger. I am not going to get into competitive racing, and will not be using the Slash every day. Safety is also a concern, I already ordered a Lipo charging/storage bag.
1. What is the main difference between the Nimh batteries and Lipos? Speed? Charge capacity? For a casual user, should I just consider Nimh instead of Lipo?
2. Is Nimh safer than Lipo? Are Nimh batteries also prone to explode if damaged?
3. Are 2S Lipos safer than 3S, 4S, etc. or are they all prone to explode if damaged?
Based on any responses/info received, I will ask about specific battery/charger advice.
Thanks!

One of the best places, IMO, that will inform a person to the use of LiPo batteries....http://www.rogershobbycenter.com/lipoguide/

1:Nimh batteries are much heavier for lipo, and don't offer nearly as much performance. Most people will not go back to nimh once they tried lipo.
2: MOST people say nimh are safer than lipo. They can explode, but very rarely. It is also rare for a lipo to burn if not damaged.
3: A 2s lipo fire would be smaller than a 3s or 4s, assuming that they were all equually charged.
The links that RustyUs gave will anwser all your questions in depth...

Thanks for the info and links!!! It was EXTREMELY helpful, though I am still a bit confused by all of the technical specs. I’m trying to narrow down options for the charger and lipos based on the following criteria for how I will be using it:
- need a charger and some Lipos for my Slash Platinum 4x4
- I will not be racing, just bashing, and it will mostly be used on flat paved surface, and occasionally on some dirt/grass
- I’m not going to be using it all the time, possibly only once a week? Though who knows...
Batteries:
- 2S
- don't want to take any chances with larger capacity batteries that will run longer (one of the articles mentioned that the motor could overheat, not sure how likely that is though?)
- SAFE as possible
Charger:
- like to stay around $150 or less if possible, though will pay more if needed
- SAFE as possible
- Safety features such as over/under voltage protection, time out feature, temperature probe for over heat protection, cell count confirmation/protection
- adequate cooling fans and heat sinks
- balance charging to ensure each cell is properly charged - Shows all cell voltages when balancing
- ability to charge 2 batteries at a time would be nice
- auto shut off for safety reasons
- ability to storage charging
- charges different chemical battery makeups
- Can measure the Internal Resistance of each cell & the entire pack
- accurately tell me my battery condition by showing how much charge goes into them
- accept a 12-14 VDC input

The Kinexis charger is a good charger for the price.
I would stay away from the turnigy and gensace lipos. Look at a Venom LiPo as they have a much better warranty and the company is easy to deal with.
Here is some good reading if you want to learn about electric operation. It's written for aircraft but most everything crosses-over to surface.

I run Gens Ace batteries in my RC10T and SC10. They don't perform as well as Venom or a few other brands would, but they are fine for bashing and priced right. Get yourself a 2 cell hardcase lipo in the highest capacity that will fit your truck since that 4wd sucks the power. I think Gens Ace makes a 6500 that will go in there. Get 2 while you are at it.
An 80 watt charger will be fine for your purposes. As long as it's lipo compatible, it will work fine. You don't need to measure resistance for bashing.
Overheating is the result of drawing too many amps, caused by having your gear ratio too high. Follow the manual and you'll be fine.

The only reason to "update" is if the components are not in working order. Batteries do self discharge when sitting for long periods of time. Depending on age and condition of batteries, you might find some that will hold a charge.
Is that charger a peak charger, or one with a timer knob?

Batteries have a shelf life. Their internal components break down over time.
For future use, it's very helpful to take a minute and review your posts for grammar and spelling. I know some consider it picky to speak up about it, but when you use good writing people can understand you better. We can't help you if we can't make sense out of your post.
