E-Bike 48V 5A Lead Acid Battery Charger
48V AGM, GEL and flooded packs need three stages, not two: this runs CC, then CV, then float, which is why it suits a battery left on charge. 180W, voltage d...

A 180W 59.2V (or 58.8V) lead-acid charger for 48V AGM, GEL, and flooded battery packs — 3-stage charging profile (CC/CV/Float) designed specifically for traditional 48V electric bicycle and e-bike lead-acid batteries. Voltage display, sturdy shell, active/passive cooling, and standard 3-pin inline or GX16 output. Built in our own 3,000 m² factory in Shenzhen since 2011.
Key specifications
Model / battery · YZ270 series · 48V lead-acid battery packs (AGM, GEL, Flooded)
Output · 58.8V / 59.2V DC / 2A to 3A (approx. 120W–180W) · 3-stage charging profile (Constant Current -> Constant Voltage -> Float Charge)

MOQ / lead time / warranty · 1 unit · 10–15 working days · 1 year
Check two things before you order: first, ensure your battery type is lead-acid (AGM/GEL). This unit uses a strict 3-stage lead-acid charging profile (reaching ~58.8V–59.2V with float stage), which is completely different from a 48V lithium-ion pack (13S charges to 54.6V) or a 48V LiFePO4 pack (16S charges to 58.4V) — using this on lithium can cause overcharging issues. Second, check your e-bike's charge port connector (commonly 3-pin inline, 3-pin XLR, or DC barrel plug).
