Unmatched Cycle Life
You can expect over 10000 cycles at 1C charge and discharge with 80% depth of discharge while retaining more than 80% of original capacity. Daily riders get over 27 years of service. This eliminates frequent battery replacements and lowers total ownership cost significantly.
No Temperature Worries
Discharge from -40°C to 60°C. Charge from -40°C to 60°C. Store between 10°C and 35°C. BMS high temperature cutoff at 65°C. Whether you live in the far north or the hot south, this battery works every day of the year without performance loss.
The Numbers That Matter
Nominal voltage: 48V. Rated capacity: 19.5Ah (rounds up to 20Ah for simplicity). Total energy: 936Wh. Internal resistance: ≤65mΩ. Efficiency: 99%. Self‑discharge: 2% per month—so it holds charge during long storage. The internal layout is 20 series and 13 parallel (20S13P). The case measures 185 x 145 x 310mm and weighs 15kg. Terminal: 2+6 plug. Housing: cold‑rolled steel with IP65 dust/water protection. Cell chemistry: LTO. Optional 4G/RS485 SOC display available.
How Much Power You Get
Continuous draw: 20A—that's enough for flat roads and gentle hills. Need to climb a steep grade or accelerate quickly? Pulse jumps to 60A for up to 10 seconds. The BMS cuts discharge at 30V and reconnects at 40V. Short‑circuit protection fires in 200‑500µs. No voltage sag, no hesitation.
Two Ways to Recharge
Feed it CC‑CV with voltage between 55V and 57V. Float at 55V when full. Standard 10A charging tops it up in about 2 hours. Bump that to 20A and you're back on the road in roughly 1 hour. The BMS stops charge at 57V. The kicker: LTO takes high current even when the battery is frozen solid—no pre‑heating required.
10000 Cycles Means You're Done Buying Batteries
At 1C charge/discharge and 80% DOD, this pack retains >80% of its original capacity after 10,000 cycles. Daily riders get more than 27 years of service. That's not a typo. You'll wear out the bike before you wear out this battery.
Works Everywhere, All Year
Discharge from -40°C to 60°C. Charge from -40°C to 60°C. Store between 10°C and 35°C. BMS high‑temp cutoff at 65°C. Northern winters, southern summers, coastal humidity, desert heat—this battery doesn't care. It just works.
