Arf I just see in the shop the charger is not for lead acid battery... so for my project i don’t Know which battery i can use with this machine in regard with the weight. I don’t want to fabric myself lithium battery, i think it s too dangerous. I have 6 lead new battery, it s damage, maybe with another charger ? But is it compatible with pcb 1.3 to control the charge and compatible with the sender ardumower (i have an original rl2000 charger)
