## Questions & Answers

**Q: Can this be used to power my solar fence box?**
A: Check what the fence charger requires for amperage hours, I assume it is 12v volts and solar charging during the day. Lead acid batteries have a power loss at about 50% of charge/ power drops some but is usable.  LifeP04 have a power drop around 80% of used charge, will go into a protected mode 10.6volt stopping extreme power loss of the battery, the device is called a BMS battery management system. Just get the correct amperage battery or higher, you can parallel to get the current if needed for the fence charger. LifeP04 batteries will charge to full power much easier that lead acid since they do not need an extra push at the end to get fully charged. Hopes this helps.

**Q: Is this a good battery for boat**
A: HWE 12v 7ah not only perfect for boat for fishing-finder, but also for solar energy storage, house alarm security system, emergency lighting power system, automatic garage door, outdoor camping, and household power supplies.

**Q: The chart shows max discharge current = only 7a. it must be ≥ 45a to replace same size lead-acid battery in a ups. do you have such a lifepo4 battery?**
A: Yes, our battery with consistant current 7A and peak with 30A for discharging, because it's a built inside  smart BMS to protect battery during charging and discharing.   If must be above 45A, we suggest you use 2 12V7Ah battery in parallel of use other battery with bigger capacity.

**Q: Is it safe to use for fish finder on a kayak, high humidity or wet environment?  What charger work for this battery?**
A: The waterproof rating of our 12v 7ah LiFePO4 battery is IP65, and our lithium battery was build-in a BMS protection system to protect the battery from short-circuit problems. It can be safely used in your fish finder.
Per the charger, we recommend using a professional 12.8v lithium battery charger, which can charge efficiently.
