Hi I’m using a 6.0 Volt Ni-MH 1600mAh Battery Pack (that I bought from Lynxmotion) to power some servos. I’ve been using the battery for a while and now the voltage reading is 5.7 volts.
I have a charger (from an old RC car) that has the following specs:
AC ADAPTOR
Model No. DV-1230
Input: 120 VAC 60 Hz 6W
Output: 12 VDC 300mA
My question is, is it safe to use this charger to recharge my battery pack? If not, what type of charger should I use to charge the battery pack?
NiMH can be charged from any charger that can do NiMH or NiCad. The charger needs to detect the peak of the charge. What you have posted sounds like a simple wall pack. This is probably designed to trickle charge a battery, or as a supply to a built in charger. But it does not sound like something that will charge a NiMH pack. From what I remember trickle charging a NiMH pack can only be done after a normal peak detecting charge.
Here are some pictures of the charger:

I would be good if this could work, but I may have to buy a charger. I used the battery that can be found here:
What sort of battery came with the RC car???
That bulbus thingy inline with the cable may be a charging circuit…
It came with a 7.2 Volt rechargeable Ni CD Battery Pack. I don’t have the battery with me right now, but I can post a picture of it on Monday if you need to see it.
No need for a picture. Best guess is it might work. Only down side is it was designed for 7.2, not 6.0. So I dunno…
I was hoping that wouldn’t matter. The reason I say this is because there are two universal chargers for sale from Lynxmotion:
2.4 - 7.2vdc Ni-CD & Ni-MH Universal Smart Charger
6.0 - 12vdc Ni-CD & Ni-MH Universal Smart Charger
Both of these support a range of different battery voltages. But the charger I have does not explicitly state this.
Is there any danger in trying the charger out? Will the 7.2 volt battery charger blow up my battery and burn my house down if I use it with a 6 volt battery pack? 
If I buy one from lynxmotion, which one should I buy?
The two chargers we sell are pretty much the same. If you don’t need to charge a 12vdc battery the other will charge a little faster.
The charger is not likely to burn. It’s only got 300mA of current. The most likely fault would be it wouldn’t charge properly or not at all.
is this a cross-post? Seems like the same question was asked in another thread.
