Contact us for pricing or to purchase.
AMPTRON® 48V 75Ah Lithium LiFePO4 Batteries are an alternative replacement (AR) for most applications currently using a deep cycle Gel, AGM or Flooded Lead Acid battery. The high peak discharge current makes these batteries suitable for high load applications such as in most standard size 48V electric golf carts, utility vehicles and other 48V applications utilising electric motors. The 75Ah capacity usually allows at least 2 full rounds around a golf course without recharging.
