36v 60ah lithium batteries, with guage and smart BMS app $1000 each

[FishingwithRusty]

this is the same battery ive been running in my boat for the last 2yrs without issue. Ive got 4 of them for sale. if you have a Stealth or Powerpole charge you can run just one battery as i do, if not you would likely want 2 in parallel. weighs less than 40lbs.
