My charger burned out so i went to the Thrift store and bought a couple cordless drill chargers to obtain the right voltage and they have been working great for two years now. My scooter is 48 volt so i got two chargers that equal aprox 55volts and never any troubles : )

Modifying a battery is the same as building a new battery. See this thread: https://electricbikereview.com/forums/threads/electric-bike-battery-repair-repacking.16033/
A 60 v battery would require 2 more cells in each stack compared to a 54.6 v full charge "48 v" battery. It would require a new case. The cells you buy should be the same discharge current, type, and age of the old cells. Not likely to happen the sort of wild west electronic supplies are on alibaba. Welding cells together is not for newbies, can potentially burn your hands off, and can potentially burn down the building you do the welding in. I have a welder and I weld outside on the dirt in good weather, not in the garage it would cost me $40000 to replace. I don't weld lithium Ion cells. Others do on that thread.
I'm not going to tell you who the reliable battery suppliers are in the US since you live in France. I will say I bought one pile of trash described as a battery on Amazon. I bought another from E-bay. I got my money back from Amazon, not E-bay. you have to prove your order is trash, not a battery, in under 31 days to get a refund.
I built my own 4 A 54 v charger out of a 45 VAC transformer, capacitors, resistors, semiconductors, fuses. Peak voltage is 1.4 x nominal winding voltage, -1.4 v for the two rectifiers. You'd need a 48 vac transformer for 60 v I imagine.

Hi indianajo, and thank you for your help and time,
yes i well add 2cell S to up V and to cell P to up A,
And for battery i build it only with spot wilder, so it's easy, i need just to now ho to calcul resistance to now what resistance i need to up charger to 60v.
