I wired up the 24v 100ah LiTime and gave it a whirl today.
For starters, I weighed my x2 old lead acid TM batteries and they came in at 63# a piece (126# total). My old on board charger I removed was another 14#. The LiTime on a scale was 41#. I also have it so the terminals are accessible from a side compartment so I’m going with the Dakota Lithium 5ah 24v portable charger. I netted a cut of 97# in the front of my 17’ boat. This wasn’t the main incentive but worked out nicely.
I used spot lock intermittently in a light current on and off for a couple hours, then drug some chubs around with it slowly in a bit of current for another 45 minutes. When I checked the Bluetooth app, I had used a whopping 10% of the battery.
Barring some major surprises or failures, this was a slam dunk upgrade
