Team Losi- Portable Alkaline charger

       Remove this ad - become a site supporter!
Hey guys.
I bought a Team Losi micro T for one of my kids. These come with a portable charger that uses 8 AA alkaline batteries to do the charging. These power the charger to charge the battery pack in the car. My question is, can I safely use MH batteries in the charger rather than alkaline?

Re: Team Losi- Portable Alkaline charger

You can. But why? There are better options out there.
You have to understand there are some limitations to the charger. This changes with the type of battery you are using

I dont know the circuitry of the charger or the battery it is charging, so I will explain some of the techincal issues and you can make your own decisions from there.

1) The difference in operating voltage between alkaline and NiMh is 1.5V vs 1.2V per cell.
This means an 8 cell battery box in alkaline will have 12V nominal vs the same 8 cells in Nimh which will have 9.6V.
So with NiMh, you are already starting off with less voltage in your charger than it would with Alkaline

2) what is the cuttoff voltage of the charger?
The charger probably has a cuttoff voltage programmed into it. It measures the voltage levels of the alkaline batteries (as a whole- not each individual cell). When the charger detects that the batteries are low, it probably sends an alarm or shuts down the charger. While I dont know what this threshold is, lets say for arguments sake that the voltage threshold is 9.5V. Given a 1.5V Alkaline (12V for 8 ) you could recharge the car pack say 5 times before you drain the alkaline batteries to the point they hit 9.5V and shuts down
But for NiMh batteries, you might only be able to charge 1 car pack before it hits 9.5V and shuts down. This can become very frustrating because you are constantly trying to keep the NiMh batteries charged

Work arounds:
Q: Is this going to be used as a portable device or charging from home?
If it is going to be used at home, why not just get a 12V power supply, hook it up to your charger and be done with it?
Or better yet, just get a good intelligent charger with a built in power supply that is 10x better than that losi charger for about 40 bucks?

If you need portability, again, the best option is to go with an intelligent charger I mention above. The one I recommend is dual power- 120V for at home and 12 V for on the road

If you want portable power with what you currently have
1) get a 12V gel cell and wire a lead from the battery into the charger you have now
2) Assuming you are running your car at a track/field, you can hook up 2 leads with alligator clips to the battery box and tap 12V directly for your car battery
3) use *9* Nimh Batteries. This will require an external battery box. 9 1.2V Nimh Batteries will make 10.8V and last you that much longer before your charger senses the input voltage is too low. This option is the least that I would consider for but I wanted to mention it to you as an option. (you could go with 10 batteries, but 10 freshly charged NiMh will output more than 12V when you first put them in, which could potentially damage the charger due to over-voltage; Again, without looking at your charger, its hard to say what its maximum rated voltage is. Some are designed to operate between 10-18V, and others are not.)

Just out of curiosity, what kind/brand/voltage/capacity is the battery that is being used in the car?

Re: Team Losi- Portable Alkaline charger

I'd have to check to be sure, but I believe the battery pack voltage is 4.8
