Go lithium 16 volt battery and charger. The battery is a 20ah battery but will need to be repaired. will charge up to 16volts and show full charge until load is applied. The battery is a year and half old and was run in a dirt late model. 10 amp Charger is a year and half old and works perfect. Have charged a good battery and works like it should and charges fast. I have 3 chargers for 16V batteries so selling 1 charger and 1 battery as a package. Go lithium does repairs on batteries and are reasonably priced on the repairs so battery should be repaired. Charger is good to go. 25.00 flat rate shipping
