can I only buy the wire that connects to the battery on one end?

The cables are compatible with other battery tender products. Search for battery tender cables to find what you are looking for.

Will the charger wake up my battery. I have 30ah eco worthy that shows it’s at 4.7 v. Thank you

Generally, the occurrence of 4.7V in the battery indicates a battery cell malfunction, and the charger is generally unable to repair it. Activation can only be considered when the battery shows 0V.

Have a eco worthy 100ah 12 lifep04 battery. at 11.7v does not seem to charge. why does amp show 0?

I have used this unit to charge a 30 amp hour lifepo4 battery with no issues. The charge time required for a 100 amp hour battery @11.7 volts would be rather long. I do not know why the charger is reading 0 unless it is not detecting the lifepo4 battery. At the minimum it should display 11.7 volts. When I plug the battery in the charger detects and flashes charging amperage and voltage alternatively. It may be a back connection between the battery and charger unit. Hope this helps.

Does this charge lifepo4 batteries, or is it a lifepo4 battery that is used to charge various thing?

The 5Amp 12V Automatic Smart Battery Charger is mainly used to charge 12v lifepo4 batteries, and can also support 12v lead-acid batteries
