If you’re upgrading your golf cart to lithium, you already know the benefits, lighter weight, longer life, faster charging, and little to no maintenance. But once you’ve made that decision, the next question is: which battery brand is the right investment?
Two of the most recognized names in the lithium golf cart battery market are Allied Battery and Eco Battery. Both offer U.S.-based engineering and performance-driven products. But when comparing their big bank systems, important differences emerge especially for users focused on reliability, safety, and deep-cycle performance.
Brand Overview: Allied Battery vs. Eco Battery
🔋 Allied Lithium
- Heavy-duty steel casing for protection and durability
- Built-in fire suppression technology
- 2A Dedicated active balancer for real-time power distribution
- Remote on/off switch for added control

- 8-year full replacement warranty on most major battery packs
Why Active Balancing Matters
All lithium battery packs must keep their internal cells balanced especially if deeply discharged. Allied Batteries includes a Dedicated 2A active balancer, which redistributes energy between cells continuously during charge and discharge. This ensures performance stays consistent and reduces the risk of long-term imbalance.
Eco Battery uses passive balancing managed by the BMS, which works more slowly and may require extended full charges to correct imbalance. For deep-cycling and heavier use, active balancing offers a huge advantage.

Final Thoughts
Both Allied and Eco Battery offer strong lithium solutions for golf carts. Eco Battery performs well in most builds and offers a generous warranty. But for deep-cycle use, long-term reliability, and enhanced safety, Allied Big Bank stands out with better construction, faster balancing, and more robust control.
