Hello everyone, I am starting a new business with RC car rentals. We are using the BRP 1/18th scale cars as rentals but are not sure which way to go as far as batteries. I was thinking of using AA's in a 4 pack configuration but was unsure of what type cells would be best. Any help would be appreciated. Thanks.

If you go AA's check out cheapbatterypacks.com. They are better that the duracells and such you will get from Wal-Mart.

Now if you go Li-Po, I would look at 1cell not 2-cell for rentals. If you go 2-cell you will be working on alot of stuff. But you could just tune-down the esc to prevent the high speeds 2-cell would provide.

If you don't go with the Li-Po packs look at using AA's that are hybreads or "Pre-charged". They hold a charge on the shelf so you don't have to to re-charge packs that have not been run for a week or two. They will hold about 80% of their charge for a year.

If you go Li-Po be sure the ESC has a li-po cutoff or you add one to it. If not you will be replacing the packs much sooner. If a li-po cell gose below 3v per cell or above 3.7v per cell they will be damaged and gas out or puff up. The gas is highly explosive.

Li-po's are great and can give you 10 times the service life but you have to insure they are not abused. I know how abused a rental can become.
