![]() | In Series or Parallel, It's Up to You
- You can connect these GEL batteries in series or parallel to power your system. But please note that the maximum number that can be connected in parallel is 4. As for in series, there is no limitation. - We recommend connecting batteries with the same voltage and capacity from the same brand. |
NOTE
· We recommend only using consistent battery types. DO NOT mix new and used batteries together as it will reduce overall performance .
· To avoid cycle-life shortening, we recommend not discharging the battery below 40%.
· It is highly recommended to use a battery balancer to extend the battery service life when multiple batteries are connected in series and/or in parallel.
· We highly recommend installing the battery upright. It is allowed to install the battery on its side only if there are special reasons for doing so. DO NOT install the battery upside down.

FAQ
1. How many life cycles does this GEL battery have?
This CASISolar 2 Volt 400ah Deep Cycle Gel Battery enables more than 1000 charge/discharge cycles at 50% DOD (Depth of Discharge) in cyclic applications.
2. Will the battery come with the terminals? And if not, what's the size of the connector terminals?
Yes, it comes with two copper screw terminals. The size is M8 x 1.25 x 16 mm.
3. Can your gel battery be charged by e-bike charger with AC?
Depends. The charging current should be less than 0.25C10. For example 25A is the max for 12V100AH battery. So only chargers within the permissible voltage range can be used.
4. How to properly store the Gel battery?
Store it in a dry and cool place at -30℃~50℃. Charge it to full before delivery and recharge after three months.
5. How can I fix this GEL battery if I over discharged it?
It can be restored to normal voltage and continues to operate normally through low-current charging. Please note that frequent over-discharge may cause irreversible damage to the battery's life. To avoid cycle-life shortening, we recommend not discharging the battery below 40%. You can contact us to make sure your system working in balance, info@casisolar.com.
6. What is the maximum charge current? Optimal charge current?
The max charge current for this battery is 60A. The optimal charge current should be based on whatever the charge controller will give it as the optimal charges based on the current level of the battery. An intelligent battery charger or solar charger will take care of the optimal charge for the battery.
