Default Quickest way to charge HPI BAJA 5B servo battery

So what is the fastest charger for the BAJA 5B servo battery or can i buy a different battery and charger for it? The stock one takes 6 hours for 45min of run time and you cant buy a second battery to charge or what??

You can get faster charging NiMH, but I recommend going Lipo if you want fast charging capabilities and longevity.

I charge my stock Baja battery from a Triton II. It takes under an hour even at 1C. Don't waste your money to get more capacity. My battery goes 4 tanks on half a charge - more than enough for a full day of anything.

4 tanks on half a charge?? Really? Cause the BAJA manual says only 40min to a tank and 45minutes of runtime to a charge?

you should get a lot longer than 45 mins on a 3000 mAh 6V NiMH... With a 7.4 Lipo even longer.... You need to ensure you have servo's and a receiver up to the 7.4V or get a voltage reducer.

I watched the battery carefully because I was almost talked into getting a 4000 mAh right off the bat. Glad I didn't.

Remember the car is only running two servos. Average servo draws are less than 200-250 mAh each. That gives you at least four hours to a charge. I check my battery religiously and it has never taken more than 1100 mAh after a full day of operation. One tank drains under 200 mAh.

You *must* make sure that you cycle your battery first to get max capacity out of it, however. On the first charge it might only take 900 mAh or so. You can't cycle it with a wall charger. I *strongly* recommend that you get a charger that can tell you how much is going in and out of the battery.

Not familiar with that one. It will need to have a digital readout and capability to cycle.
