Why this charger lasts
In CC mode the charger pushes a steady 2A into the pack until it reaches 42V, then switches to CV mode and holds 42V while the current tapers to about 5–10%. That taper is what stops the pack being overcharged — the difference between a battery that lasts its rated life and one that comes back as a warranty claim.
Active cooling
A high-speed fan moves air across the power stage, and the shell itself is an aluminium heat sink. Heat is the biggest killer of charger lifetime.
Fireproof housing
The enclosure uses fireproof material, so a fault inside the power stage stays inside it.
Four protection layers
OVP, OCP, SCP and OTP. Charging stops on a fault and resumes automatically once it clears.

CC/CV charging curves for lithium and lead-acid packs — and the conventional-parameter matrix from 3.7 V to 96 V — are on page 2 of the technical data sheet.
This 42V build is one configuration of a platform we build from 1 series (3.7V) to 23 series (96V) and beyond, for lithium, LiFePO4 and lead-acid packs. Not sure which build fits your pack? Ask us.

Own SMT lines, assembly zones, aging chambers and IQC / IPQC / OQC checkpoints sit under one roof; every unit gets a 24–48 hour full-load burn-in, and your order runs through three inspections before we photograph it and dispatch. Certificate copies are available for your technical file.
Frequently asked questions
Are you a factory or a trading company?
We are a manufacturer, building chargers in Shenzhen since 2011. Our 3,000 m² facility has its own SMT lines, assembly zones, aging chambers and QC stations, with a monthly capacity of 150,000+ units. We welcome factory visits and third-party inspections.
What battery does this charger suit?
A 36V (10S) lithium-ion pack. 42V is the full-charge voltage of 10 series lithium cells at 4.2V each, so a 42V 2A charger is the correct match for a 36V lithium e-scooter or e-bike battery — electric scooters, e-bikes, hoverboards and personal mobility devices.
Can it charge a 36V lead-acid or LiFePO4 battery?
Not with this 42V build — a 36V lead-acid pack (3S) charges at 43.5V and a 36V LiFePO4 pack (12S) at 43.2V. We build both versions on the same platform; tell us your battery type and we will quote the right output voltage.
