I have a Master's degree in math, but it is for education not engineering/electrical. I'm a math teacher/assistant principal and I share a lot of what you guys teach me in the classroom. The students love it. Several are helping me build a huge track on my land. We live in the country.

Yep, that is correct to get amp ratings.
A correct C rating is vital to battery selection, but the resellers do lie to make their products more attractive...
Generally speaking the only Chinese packs I would suggest are True RC and Zippy, as their ratings seem to be solid and true. Not sure where the RCM lipo cells are from, but they have honest ratings too.
Any enerland mfg cell is a good bet too. These companies use enerland cells: Thunderpower, Flightpower, Neuenergy, Polyquest, Polyrc, Hyperion, and Outrage (not 100% on the last, I have not personally taken them apart). Pretty easy to tell an enerlan pack, as it will have the solder tabs at each end, where all of the chinese cells that i have seen have the tabs side by side on one end.
Enerland cells are built to tighter tolerances and have better quality control. So you have a better made cell that is matched to the other cells in the pack properly. So the pack will stay in balance and perform well. Once you hold a single enerland cell in your hand and a chinese cell in the other you can really see and feel the difference...
Glad to hear that you involve the kids in the hobby! Have fun with the track! |
