i went to a vendor site to order 2.5ohm dual coil cartos, and this is what is states:

The 2.5 Ω carto has two 5 ohm coils run in parallel giving a total resistance of approximately 2.5 ohms.
The 2.0 Ω carto has two 4 ohm coils run in parallel giving a total resistance of approximately 2.0 ohms.
The 1.5 Ω carto has two 3 ohm coils run in parallel giving a total resistance of approximately 1.5 ohms.
The 1.25 Ω carto has two 2.5 ohm coils run in parallel giving a total resistance of approximately 1.25 ohms.

Please don't use the 2.0Ω or 2.5Ω on 3.7v PV's (not enough voltage), they work best on 5 - 7 volt devices!




i currently use 2.0 boge single coil cartos on my ego and they work great, so i don't get why they say don't use 2.0's or 2.5's on 3.7v pv's??

LR = 1.8Ohm or lower best suited for 3.7V
SR = 2.2-2.5Ohm best suited for 3.7 - 5V
HR = 3-3.5Ohms best suited for 6V
XHR = 3.5Ohm plus suited for 6V+

LR are designed to be used on high drain batteries e.g IMR or Lithium manganese. These have the capability to supply the current demand.

When it comes to DCs, the chart above explains why the 2.0 and higher requires higher voltages, to meet the current demand. Although the DC is 2.0Ohm, you are still running 4Ohms of resistance x 2.
