Product Description
high capacity 72v 40/50/60ah lipo battery

Hello. This is Margaret from Melsen. Melsen is a pioneer in the lithium battery market and a unique lithium battery solution company. LiFePo4 and NMC(Li(NiCoMn)O2) are the major material. 

Melsen lithium battery flat pouch cell can be composed into various battery packs by series and parallel connection,such as 12v/24v/36v/48v/72v/96v/108v/110v/120v/144v 12ah/15ah/20ah/25ah/30ah/33ah/40ah/50ah/60ah80ah/90ah/100ah/120ah/150ah/160ah/200ah, and so on.

Lithium polymer battery modules in parallel or in series, can be used in electric vehicle, E-bike, UPS, energy storage system, telecommunication base station, E-scooter, E-tools, unmanned airplane, golf cart, fork lift, cleaning car, electric wheelchair, etc.

Battery quality control for after-sale
All of Melsen battery cells in a pack are with very high consistency.In a pack, each cell has its own sole electronic code(ID number) for quality control after-sale. Assume one cell in a pack is damaged in any reason after several years later, we could provide a exactly same cell to the client to replace this damaged one(same voltage, capacity, impedance,etc.), in order to make sure all of the cells in this pack with very high consistency. Melsen has a strong system working for this.
