What is the diference between lyen and EMC EV 84-132V??

[chucho]

What are the main diferences between this two controlers? Why do they have that big difference in price?
Why to buy one or the other?


EMC EV Specification:

18pcs of Genuine IRFB4115 Mosfets.
Recommended 60-120V operation, 135V max
50A Current Limit
6mm2 (>10AWG) High Temperature Silicone wires used on Phase and Supply cables
Dimension: 257 * 85 * 45mm
Weight: 0.84kg

Lyen Specification:

Model: EC-184115-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: Confidential
18 x genuine IRFB 4115 MOSFET N-CH 150V (tested up to 150V before damage)
120V battery optimized (for higher or lower voltage & current such as 84V-132V, you may need to program the low voltage cutoff. Be aware the absolute battery topped off or fully charged voltage cannot exceed 150v)
45A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off at default: 95v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped) Silicon wires installed!
Dimension: 9" x 3.4" x 1.75"( 229mm x 87mm x 45mm) plus mount extensions
Total weight: 805 gram

probably no difference, but it don't mention what versions the controllers are.
