Cell
Although it really depends on the model, most are 12V.Do You Have The Old battery how many cells does it have,most 6volts have 3cells and 12volts have 6.It all depend on the tractor some use a motorcycle battery.
decreasing cell size mean increasing cells/cluster and while every cell have BTS (base station) so i can have mix of frequencies with condition that noco-channel interference happen unlike if i have large cell size so i 'll hv small cells/cluster. as example : i hv 3cells/cluster i.e 3 BTs if 1st BTS give frequencies (3,8,6,7) 2nd give (5,4,2,1) 3rd give (11,12,13,20) so i can use these frequencies no more to avoid interference but if i hv small cell size i can use more frequencies while i actually avoiding the co-channel interference
