which brand of chargers do you use or do you just go with the adapters that come with the tanks?  I don't think those provided are the best.

Jarlath has made a good post on this. I'll try to find it and insert the link.
For me, I have a couple of chargers. One is a Venom Pro2. I can adjust the charge rates. Charges multiple style batteries. And I have all the connector ends for the different batteries. I am still working on standardizing them. Any quality charger that has these options will be better than the USB charger or simple charger that comes with a tank. Your batteries will last longer and hold charge better.

please don't tell me you spent $250 for that Venom Pro2?  I just want something under $100 with Tamiya connector since all of my batteries are with Tamiya connectors (same as my Tanks).

OK. A cheapish and decent charger is the following from Amazon.

This will do most any type of battery that we use in our tanks/rc cars/etc...

You would need to buy an Adaptor however for the Tamiya Connector, or I could likely make you one... (This one I listed would be a Dean's to Tamiya adaptor)

thanks General.  I have no problems cutting off the Deans T connector and replacing them with a Tamiya connector.  Right now I have, from Amazon, a HAISITO charger for $66 which I will be testing.  That's about the range I am comfortable with.  I'll give you an update later.  Thanks again.

No. ha haa. The Pro2 I got was about $80 at the time. Since then I also got a Lectron charger that does everything I need it to do. That one was about $50 at the local hobby shop. 
American $. Witch, according to Ren, is about $1000 Canadian.  

Can't remember what I paid for mine

I guess no LiPo charging? 

Nope im not into lipos

Lipo's are higher performance for higher cost and higher risk (maintenance).

Not for everyone and with lighter tanks, not really necessary.

From Amazon I ordered a Haisito charger but when testing it out the instructions and programing got so complicated that I am returning it and ordered a smaller less complicated charger.  I guess simpler is really better.  To paraphrase "K I S S".

hey go to HITECx1 mini charger under 75.00 it will charge any battery and also discharge same very good charging system even for us older guys Doug
