In addition to the 24v 10ah pack I also bought a 36v 10ah pack. This is meant for my Electra Townie, WE 36v BD motor w/ 35A controller. I've also bought a 36v 15ah pack and it's due to arrive soon. But this is some test results with the 36v 10ah pack.
On wednesday I started to ride it to work but the pack cut out 2-3 times in the first 1/2 block so I took it home and rode a motorcycle instead. Today I wanted to test it more carefully.
First test.. I have a big honkin variable resistor that's rated for 300+ watts. Using that I could demonstrate 20+ amp discharges. I don't remember right now the specifics.
The voltage does dip quite drastically. At the fully charged state it's 46v. Since it's should be an 11 cell pack that works out to 4.1818 volts per cell. However it quickly drops to 42v and as the discharge rate rises the voltage drops down as low as 36v. I haven't observed a full discharge so I don't know the extent of this.
The pack did cut out a couple times during this test.
I installed the pack again on my bicycle and took it out for a spin. First I simply held the wheel off the ground and let it run w/o load. Even at full throttle it didn't run over 10A discharge but applying the brake a little raised the discharge rate above 20A.
Riding it I was able to experiment a little with where the pack is cutting out. This occurs between a 20A and 33A discharge.
Clearly with this pack on this bicycle I'll have to be extra careful with the throttle. And clearly that's going to be hard to do. However at moderate throttle this bike moves reasonably well. And the throttle is a little sticky and can be set to hold a 6A discharge rate which provides a very nice assist.
The BMS part of the pack was a bit warm after 5-10 minutes riding around.
The ratings are:-
Rated voltage: 36v Capacity: 10 AH
Weight: 3.5 KG
Suggested load: 400 watt, max load: 700 watt
CHarging voltage: 46v (max)
Charging current: 5A (max)
Rated discharge current: 10A
Max continuous discharge current: 20A
Cut-off current (max current): 35A +/- 5A
