Does anyone have any feedback on the 36v10ah Nimh Batts from www.batteryspace.com? I'm wondering if they can really handle 30amp discharge. Thanks
Hey Ric, glad to see you made it here. Weren't you asking about these batteries a couple months ago?
I have a pack from batteryspace made of their 9AH D cells .. I got the pack a couple years ago and they may have improved the cells since then .. e.g. mine is rated at 9 AH while now they're rated at 10 AH. I notice they list the rating as so:
Discharge rates above 1C (you're talking about 3C) is not recommended and warrantied. I'm interpreting it to mean you shouldn't do it on a regular basis and that the farther above a 10 amp rate you go the dicier it will be. Even their F cell pack has the recommended and warranted rate at only 13 amp.
My experience with the pack I have is .. I tried using it on my bike with a wilderness energy 36v 35 amp brushed system. This is the same bike I showed you last fall at the EV rally, that I showed you with a pair of DeWalt packs for it. With the batteryspace 9AH pack, the pack would get very VERY hot when discharging at the highest rate (35 amp controller .. but I don't know the actual discharge rate) and sometimes it did not properly charge up after a discharge like that.
I recall that ChasB has an F cell pack from batteryspace and last year he was very happy with it.
