This is a little thread i decided to make because i think that some person have various information and opinion regarding the Battery sold from PingBattery.com and i decided to make a highllight on my personnal experiences and opinion.
These battery are a very good choice when people dont have the time or dont want to build their own battery and also want a SAFE battery that they can sleep while it is left connected on the charger
These battery also offer decent power over the standard ebike battery ( about 2-3C easy) so at 48V-15A you get burst power of about 2500W and with a 60V 20Ah you get 3-4kW.
I still today have good opinion about these battery and the seller due to my personal experience and my familly experience and also friend that i have recomamned these battery too.
Ping batery are not perfect but If you buy some Ping battery and do some little mod, they will certainly become one of your best battery for the price!
I bought 7 of the 48V 15Ah with v2.5 signalab BMS 5 years ago( back in 2008) and today they still give above 14Ah all the 7 battery!. These are used by my familly ( oncle, cousin grandma etc) and they follow exactly the advices i recommanded and these battery ALL work good today
btw these 15Ah ping are used with 4C burst( 60A on a 40A controller and 2C constant average and charge at C/3 ( 5A charger)
I can still recommand Ping battery today.
Ping is a great guy and will agree to customize your battery for only few buck and can also sell you some spare cells even if your battery maintnnace skill is not so good.
These battery are good also because they use LIFEPO4 cells that avoid your ebike to have a max top speed affected over the discharge
They also have about 1000-2000cycles compare to 300-500 for the lipo or liMn
Here is some tips:
Maintenance:
- NEVER leave your battery discharged for more than few days
- Avoid fully discharge your battery ( keep at least 1-2Ah)
- in storage mode: disconect the white Balance connector ( this will avoid draining the 4 first cells channel)
- in storage mode: keep your battery between 40-60% SOC ( easy to do, fully cahrge it and make a run of 1/2 of your total Ah)
- in storage mode keep your battery in an area of about 10-20 celsius or close to that
- once all the BMS led are ON, dont leave your charger connected for more than one day
- ensure that you ocasionally charge your battery to get all the BMS led ON ( meanng your battery is perfectly balanced)
- avoid droping it and install some additional foam around it to avoid your bike rack structure to torture your battery due to vibration
MODS
-Replace the stock charging mosfet of the BMS with a 4110 and beef up the related traces ( the stock mosfet is crap and at 5A will burn un the first 100 cycles
-replace the stock discharging mosfet with the 4110 and install a copper plate as heatsink! This will make yor BMS to run coller and might allow a little more voltage output.
- on the aluminum cahrger, remove and replace with a jumper the surge supressor in serie at charger AC input on the PCB ( it look like a ceramic capacitor shape) This component often burn and is not really usefull it only damp the AC surge current when you power On your charger
-replace the crap XLR connector that often end out to melt and make bad contact
total cost of the mods about 30$
