The connector has 0.100 in. pin spacing with 0.025 square pins and fits

Apogee and other brands. Pins should be in order of Voltage.

You may wish to purchase a Thunder Power adapter, P/N 549. Thank you.

IMPORTANT NOTE: Ninety percent of the battery packs on the market are wired in sequence. If your battery pack is NOT SET UP WITH A STANDARD CONNECTOR WITH THE VOLTAGE ON THE PINS IN SEQUENCE (expl. 4v, 8v, 12v) you will be putting 8 volts across the adjacent pins instead of 4 volts and one of the lights (led) with burn out and depending on how long you leave it on as it gets really, really bright like high beams  on a car (unplug asap) you could burn out the resistors and transistor so please observe the sequence of your connector. If you are uncertain of the sequence/voltage then you may check it first with a volt meter.

The old fma packs had 5 pins and then a gap at the top, then the newer ones had 5 pins and a gap at the bottom. Now some have 5 pins with no gap.
