Yet another CRF 250 Build but its my first so... ;)

About to buy a 20s13p battery from Amorge myself with a similar shape. Going with their Lishens instead of the Samsung 50S. P42A/P45B is way too out of budget for me.

I thought about going 50S because at 13p I'd get 65AH with a peak of about 335a. I would use 300a continuous at most. Then I thought it might not last even though theres 13 extra AH, due to heat from using the cells near their peak often while riding. Would cost me around ~$1450 for the 50S cells, ~$1900 for P42A, but ~$1000 for Lishens.

Going to pay tomorrow morning

@unluckypanda
I was at the same point as you now.
I took the time to watch this Video and try to learn everything about the cells along the way (thats a freaking 4H+ Video xD)
but the guy put a lot of effort into this:

but after watching this I sattled on the Molicel P45B as it gives me the most bang for the bug for my build as of right now.

Today is the day I just placed my Order at Amorge


so my final Battery Shape for the Honda CRF 250 2009 (same frame from 2006-2009) is:

Molicel P45B
22S13P 81.4V 58.5AH (Optional 20S14P 72V 63AH but I went with 22S)
Metal Casing
Open Discharge (BMS only for Charging)
QS10 Plug for Discharge
XT90 Plug for Charging
QS10 Plug Battery Leads 650mm Length
10A Charger
Shipping by air









Molicel P45B
22S13P 81.4V 58.5AH

so this Battery pack will give me:

Total Number of Cells in the Pack: 286.00
Battery Configuration: 22S13P
Pack Capacity: 58.50 Ah
Pack Energy: 4633.20 Wh
Pack Max. Voltage: 92.40 V
Pack Nominal Voltage: 79.20 V
Pack Cutoff Voltage: 55.00 V
Max. Discharge Current: 585.00 A

I plan to set the controller for 300A continuous and 450A Peak so I am still on the very safe side I guess.
