Inside these power packs are also battery discharge indicator (see below) to show the remaining charge left inside the battery, these meters will be used later in the conversion process as battery string monitors (6 strings 12 volts each = 72 volts total system voltage).
Each power pack also has a 250 volt dc fuse, Anderson type battery plug in, heat sink with 12 volt mini fan, shunt connectors, 12 volt work light, 12 volt accessory socket plug in and as a added bonus lots and lots of screws.
Screws for free free, free, free
I will have extra amp meters as seen above for free and can ship you one or two, you pay for postage or I can drop them off to you if you are local. If you need any email me email@example.com
