| How to charge it? | With any 12V multi stage charging source, or time limited single/double stage. |
| Maximum charging voltage, current, ambient temperature? | 14.4V, 70A, 50 °C |
| What settings for multi stage charging? | 14V~14.4V absorb, 13.2V~13.3V float |
| What about higher float like 13.8V | Permitted if not applied indefinitely. |
| Can I use it in a dual battery system? | Yes, but not under the bonnet. Charging current must be limited to 70A either by wire resistance or DC/DC charger. |
| How to store the battery for long periods? | In a cool dry place, 50% charged, all wires disconnected from positive terminal. |
| Does the bluetooth module drain the battery when sitting idle? | No, the module goes into low power state when not actively communicating with another b/t device. |
| How accurate is the SOC reading? | Reasonably accurate initially but can drift with higher cycle count.. |
| How to keep the SOC reading accurate? | Charging the battery to 14.4V will re-establish initial SOC accuracy. |
| What happens if the BMS isolates the battery during charging? | That depends on the charger or solar regulator. E.g. Victron blue solar MPPT controllers with updated firmware aren't fazed by this. |
| Why would the BMS isolate the battery when almost fully charged? | The charging voltage could be too high, or the cells need re-balancing. |
| Do the cells need to be re-balanced after some time? | That depends on how the battery was used and charged. |
| Cell voltages are within a few milli Volts but start to diverge above 3.5Vpc, is that normal? | Yes, perfectly normal for this type of chemistry. |
| How to re-balance the cells? | By plugging the battery into a balancing device. |
| What voltage can the battery be discharged to? | The BMS isolates the battery at 10.8V~10V or when a cell drops below 2.5Vpc. |
Should I use a low voltage disconnect?
| Yes, recommended trip setting approximately 11V. |
| Can I wire two of these batteries in parallel? | Yes, but they need to be of similar SOC/voltage at time of connection. |
| Can they be wired in series? | Nope, requires another BMS module, please enquire. |
| What's the maximum current draw? | 150A |
| Do I need to fuse the battery? | Yes, the fuse rating depends on the wire gauge, max 150A. |
| What if something breaks? | Thanks to the battery's modular design it can be repaired. |
