Installing two BigBattery 72V FALCON in a 2002 GEM Car. Video will show installing one battery in the hood and the second battery in back under the seat. Six 12v flooded lead acid deep cycle batteries were removed prior to install. Note, the customer brought in the GEM with front battery tray removed.

So, the controller converts it from 72 to 12 volts to run the lights, etc? My GEM has a capacitor blown on the computer card. Can that card and the old charger be bypassed with a modern 72/12 dc transformer?

@@markblinson603 I have not tried this...in theory. It does sound correct

[@grovesville]

isolate the cables from chafing against studs.

[@MrTomatoFarmer]

How did this go? Is there enough power?

[@DeepcyclebatterystoreSanDiego]

Small gain in range

[@kdreed96]

Are 2 of these falcon batteries comparable in capacity to the 6 lead acids?

[@DeepcyclebatterystoreSanDiego]

28ah ea, connect in parallel.. the oe sealed lead acid have 100ah with 50%DOD

[@MrTomatoFarmer]

Is that a yes or no?​@@DeepcyclebatterystoreSanDiego

[@DeepcyclebatterystoreSanDiego]

@@MrTomatoFarmer customers who have the two battery kit say it has the same range as the lead acid.

[@DeepcyclebatterystoreSanDiego]

customers who have the lithium kit say range is similar to a new set of gel lead acid. Top speed a little higher due to weight reduction
