The 'M' cell batteries are industrial grade and are used for high power applications. They are rated at
10,000 mA at 3.3 volts. The chemistry is Iron Phosphate Lithium-Ion, and that makes them explosion
proof in discharge or charge operations. They can easily output up to 100 Amps in an open circuit condition.
With 4 or more of them in series arc welding is possible.
We chose the 'M' cell batteries as the most reliable battery for the intended usage for Search and
Rescue operations. Another benefit of these batteries is that they can more than double the number of
recharges of the common 18650 size batteries.
We will later make a shorter battery compartment using three 18650 batteries in a 2 inch diameter by
5-1/2 inch size for non Mission Critical uses.
The Head of the SR1500 has a control knob to vary output from zero to max and on the opposite side of
the head is the power switch. These are positioned so that with the fore-finger of either hand the light
can be turned on or off and without moving the hand the thumb can rotate the output knob.
The back of the 'M' cell battery compartment will have a removable key ring adapter larger than the
ones that we use on our other lights. It can be used as an attachment point for a shoulder strap or as a
window breaker. The light with batteries does weigh 3.2 pounds.
Also later we will have a pistol grip attachment and a remote power cord to connect to a 12 volt battery
power supply.
The SR 2000 will use the larger 83 mm reflector that we get from Phoenix. These are the best reflectors
quality wise that I have seen. The test samples from KD were junk as compared to these in both build and
spectral performance. Very impressive.
Clint:
The 'M' cell battery compartment is larger in diameter than the head of the FR series lights. We may make
a remote battery pack using the 'M' cells as a long run time option.
We have the 'M' cells in stock along with the battery charger for them. I still have to design and make a holder for charging them.
