Hello, everyone.
Thanks for the interesting forum. I read it regularly .
I've decided to upgrade the battery of the Jonway MSG-D 1000 W electric scooter. I need your opinion, and any ideas are welcome.
The batteries are SLA 5 x 12 volts = 60 V. I’m thinking to replace them with one of the following options
1. 17S12P 18650 LI ion Samsung 29E, 2900 mAh, 8 A max from EU store;
2. 17S14P 18650 LI ion some Chinese mark Lava, 2200 mAh, 4,5 A max from local store. I tested a sample. Draw 1,5A for 1,5 Hours from 4,2 to 3,2 V, 2 amps for 40 min;
3. 20 sell soft bag lifepo4 20 or 30 ah battery 3.2v high discharge battery from Alliexpress. 60 A continues. The seller says they are delivering to Europe, but it's probably not going to be easy.
BMS – on the way smart BMS from ICGOGOGO.
Currently the range is about 30 - 40 km daily. After 3500 km it is closer to 30 km. Controller is Chinese 35A, cut off 52 V. The continuous current consumption is about 20A on flat ground with no hills or climbing. The wattmeter measures 600 to 1000 Wh for daily trip – to go to work and back. At first time I will not change the controller, possibly will increase current to 45 amps if It be able with more shunts. I need also for more speed, because the max at the moment is 55 km/H. Not enough for main streets in our city, and slight up to 75 km/h will be perfect … and if it is possible for the new battery pack to provide and maintain more speed - it is welcome.
My main aim is to increase the range with a single charge up to 60 km or more and at the same time the new battery should have a maximum number of cycles. Will use everyday from April to October, eventually in the weekends the battery will have a rest ...
Will the specified configuration be enough to meet my goals and at the same time leave enough energy to keep the battery from overloading?
Are the LiFePo4 better option than 18650 LiIon?
