Need Help, Going to buy Headway's for the Big 13 Pulling tractor

PLEASE!
Looking for help and advice.

Well, the money's put aside and we are ready to buy 104 Headway 38120P batteries to power the 13 inch motor in the pulling tractor.

I'm looking for the best value since I'm retired. The $2000.00 or so is a big chunk for me so I have to get the best value I can.

The 72 volts we tried last season just didn't do it (of course the bad gearing choice I made didn't help

).

100 batteries for the tractor and 4 spares. (the 4 will probably be used as a 12 volt control battery)

We plan to go with 50S 2P to start off this year and next year we will be adding 50 more batteries as we prove out the systems and home made controller until we reach a total of 200.

Looking for advice from people who sell and/or who have bought Headway batteries.

I can wait a while since pulling won't start until May of next year. I'll also be building a Simon/Jack charger and we are looking at various balancers.

Just a thought, have you looked into the Nano-Tech R/C batteries from Hobby King ?? They are rated at 50C-to 90C discharge. Charging can be 20 minutes or so, IF you have the means.

Guys are using them for absurd e-bike use and abuse. They are pouch types. One guy even did some welding with a large series of those packs, tied together.

Might want to browse around on the Endless-sphere forum ??

There is a thread on ES about pulling a starter motor for 6 minutes, I believe, on a Honda Civic.

Also, pulling a starter motor on a High tech Ford v-8 engine, for less time. batteries took the load, still take a charge and still have not blown up.

They come in different voltage packs, lighter in weight, and the guys that are into serious battery tech, are becoming very enthused.

Fully agree with your decision, Jim. Have been following your threads. Neat stuff you are doing.

Down here, it's damn boring.
