Been running cheapo 24V controller for several hundred miles with a mix of 25.9 and 33.3V batteries.
Seems to have "sharper" take off with hard throttle ... initial surge.
2 additional eZips slated for controller upgrade ... waiting on delivery ..
Yes, I will build 2 additional 33.3V battery packs.
Laptop recycled - 8p 2160mAh = 17.28Ah
+ RC LiPo - 2p 2000mAh = 4Ah
= 33.3V 21.28Ah
Intended for eBike, re-geared for 20mph top speed.
Will pull 1C plus from stop, but only briefly.
Local hills should demand less than 1C, at specified gearing
RC added to supplement 1C+ surge requirements
9s12p 2600mAh NOS Sanyo cells 33.3V x 31.2Ah = 1039wh = 1.039 kWh
For trips ≤20mph and for "geared up" eZip for assist toward 30mph!
broke a spoke on 2013 eZip, maybe 33.3V extra torque and better surge from new controller?
I will rebuild 4 wheels for eZip.
Been waiting for mass production opportunity.
2 OEM wheels with 13ga SS spokes and washers.
2 aftermarket alloy hubs, better rims and 14ga SS spokes - got 2 WheelMaster alloy w/SS spokes on clearance, relace onto new hubs.
Will document ...
