kINGHAPPY, DAVE, WHOEVER. Bought a 18’ Duffy Electric boat. I’ll be keeping this puppy so need to figure out a turn key lithium package. 36 volts. Looking for range as the top speed is only 6 MPH. GC batteries said to give 6 hours of operation. Willing to give up marvelous technical gadgets for simplicity and minimum component count. Rodney ---

If money was no object. Drop-in lead acid replacement. I was offered MN. dist. for these. About %40 off. Still too rich for me. Actual turn-key. ---

Ok, now we have a price point!😃 On the other end of the scale. I will give you 16 X 60ah pouches. 36v nominal. 24v to 44v range. Actually a good option if you need less than 100amps. My 48v pack: ---

100ah lithium will be more than 100ah lead. If you can make 44v work, this is what I have in my Gem. It’s two 44v batteries. One will give you 100ah @ 44v nominal. Neatest package best bang for buck. I have one you can test if you don’t mind shipping both ways. ---

Let me know. The volt packs are neat. No assembly needed. The only draw back is that they are assembled in 6packs and 12packs. If you can make them work it’s a good deal.
