New modules arrived.
These LG Chem built modules contain very high quality NMC pouch power parallel 15 ah cells from LG Chem configured in 37V30Ah - 10S2P order for 1100 Wh's of capacity. The rigid steel OEM casing provides excellent compression and has connection for watercooling system. It has a protective cover over the cell tabs and terminals and there is a direct balance lead connection and two connectors for the thermistors (blue wires) built in the pack.
Balance pin-out of the 14 pin connector (Molex Microfit 3.0 - MX-43025-1400) - cable is not included.
1 X X X X 10 9
2 3 4 5 6 7 8
Cell 1 connect to - gives single cell voltage
Cell 10 connect to - gives full pack voltage
The same cells are also used for example in Opel Ampera/Chevy Volt/Renault Zoe packs. High discharge rating 10 C.
These modules are excellent for slim light-weight powerpacks in scooters, cargobikes etc.
Weighing around 10 KG.
The onboard electronics board is a cell voltage & temperature node and sends information by CAN bus to the pack's main hub.
It doesn't really have any value to DIY because you need to reverse engineer the whole protocol and CAN language. Besides, it will only tell you monitoring information. It can't shut down the power like a BMS can.
130 mm wide
280 mm high
320 mm long (w/o coolant tubes 300 mm)
The modules currently have a storage voltage and are stored dry.
Modules are located in Breda, The Netherlands, Europe.
Shipping optional if possible. PM for more info.
1 module: € 175
2+ modules: € 150/pc
per 2 with original flexible high current interconnect for series connection.
As an example, in 1 of my projects I am using two of these modules in series in a Govecs (Gen4 @ 70A max discharge) scooter for more than 1,5 year now and they pack a punch. I only charge to 4,1 v/cel. Recently after a year of use I checked the voltages and they were all still perfectly balanced. Using almost daily for commuting. Few pleased customers already also are using these modules from previous sale threads.
For those interested: I also have the CAN operated EV Powerchargers IP67 chargers which came included with the packs. Charge voltage is a bit too high perhaps for ES -> 250 VDC - 420 VDC. They retail around 1200 €.
Price = € 200 / charger.
