Frequently Asked Questions
What charger do I need for this battery?
You need a LiFePO4-compatible charger with 43.8V output voltage. Standard lead-acid chargers are not compatible. Recommended charging current is 25A to 50A for optimal charging speed.
How long does this battery last?
The battery is rated for 3,500 charge cycles at 100% depth of discharge. With typical golf cart use (2-3 rounds per week), this translates to 10+ years of service life.
Will this battery work with my EZGO TXT golf cart?
Yes, this battery is compatible with EZGO TXT models from 1996 to present, provided your cart uses a 36-volt system.
Can I use this battery in cold weather?
The battery operates in discharge temperatures from -4°F to 140°F. For charging, the temperature must be above 32°F (0°C). The battery includes low-temperature charge protection to prevent damage.
How much weight will I save compared to lead-acid batteries?
This battery weighs 81 lbs compared to six 6V lead-acid batteries that typically weigh 400-420 lbs total. The weight reduction is approximately 320-340 lbs (75% lighter).
Is this battery waterproof?
Yes, the battery has an IP67 rating, which means it is completely protected against dust and can withstand water immersion up to 1 meter depth for 30 minutes.
Can I connect multiple batteries together?
You can connect up to 2 batteries in parallel to increase capacity. Do not connect batteries in series to increase voltage, as this will damage the Battery Management System.
Does this battery require maintenance?
No. Unlike lead-acid batteries that require regular watering and terminal cleaning, this lithium battery is maintenance-free. The sealed enclosure requires no servicing.
