Okay, here's the deal:
I'm looking for some NiMH batteries. I came across these Tenergy cells on eBay.
I've been reading around Endless-Sphere and am getting mixed reviews.
Apparently they don't do too well at high discharge rates, but all I want them for is a measly 200W skateboard motor. With the 20 D cells I'm looking at the discharge rate should be about or less than 1C (24 x 10 = 240 Whrs). In fact, it may be less than this. The motor, I suspect, is rarely, if ever, drawing 200 watts. The SLAs currently in there are providing me with an "actual" capacity of about 72 Whrs, and lasting around 20 minutes. This gives me an average rating of about 180 watts, and, because my sister's board is a little slower than mine, I'm almost constantly accelerating and decelerating. I wouldn't be surprised if the Tenergy batteries lasted nearly an hour and a half at full speed. I know the batteries end up being around 8Ah, which is still almost three times what I'm getting out of the crappy SLAs in there now.
Basically, all I need to know is this: Will the Tenergy brand D cell 10000mAh work for what I want to use them for? If not which cells will for a similar price?
