what is the correct charge amperage?

1c is the safe bet which would be 5a, we regularly charge at 2c or 10a

Does this fit the RB10?

Yes it's a short pack and will fit with the foam spacer. The rb10 also accepts long batteries, but the shorty will increase steering response as it lowers weight and brings the weight over only the rear of the chassis, eliminating weight on the front wheels. For 2wd it makes it twitchy in the corners, faster and better in the air; but the long packs can make it more stable in corners with the extra weight. Short packs for tracks with lots of jumps, long packs for tracks that are mostly on the ground. 🤙🤙

Hi why do these batteries say single use instead of rechargeable?

It must be a typo. I have two of these packs and I use them for RC Drag racing. They are NOT single use packs. They work well. Have good punch and consistent power delivery.

What size are the bullet connectors, 4 or 5 millimeter?
