MAXKGO

MAXKGO sells lithium-ion battery packs, chargers, and related power-management hardware aimed at e-bikes, e-scooters, and small EVs. Most SKUs sit in the mid-range price band—complete 36 V–52 V e-bike batteries run USD 269-499, while 2-10 A chargers sit between USD 39-89. The company is online-only, shipping globally from Shenzhen with English-language storefronts on maxkgo.com, Amazon, and AliExpress. The brand’s hook is “drop-in upgrade power”: every battery uses name-brand 18650/21700 cells (Samsung, LG, Panasonic) and includes an IP65-rated hard case, integrated BMS with Bluetooth telemetry, and Anderson or XT90 connectors pre-wired for popular motor kits. Their 52 V 20 Ah “Dolphin Max” pack is frequently cited in DIY forums for delivering 1 kWh at 6.3 kg—about 15 % lighter than typical Chinese replacements—while the 5 A fast charger line advertises CC-CV profiles tuned for each chemistry. Customers are hobbyists converting conventional bikes, fleet owners repairing shared scooters, and specialty shops that need reliable packs without OEM mark-ups. They value open-spec compatibility, verifiable cell origin, and English tech support that will share BMS pin-outs and firmware files. MAXKGO competes with generic Shenzhen battery factories on price and with Western aftermarket brands on transparency. It differentiates by publishing independent cell-level cycle-life data, offering a two-year warranty handled from a U.S. warehouse, and maintaining UL-tested assembly lines—credentials few low-cost suppliers match.
