Been on a test run

[stevebills]

I took the external battery for a 4 miles test run seems okay
I picked up a volt meter on the way and its reading 39.5 volt
when I got home and how low will it drop before I can charge it back up?
The charger still thinks its fully charged and stays green light.

Hi Steve it should take a charge I would say bad connection between charger and battery there is nothing stopping it if you have disconnected the BMS

I was being thick as I forgot to join the red and black charging wires to the battery with the other output wires
and I did use 30 amp block connectors like you suggested for now it was the easiest option

I was thinking of runing without a Bms and Maybe get a ping when this thing packs up!
This is from 2007 and its a li-ion 36v 22ah but its never been used and stood since then.
I am suprised it still works to be honest.

Hi Steve

why not it works

I would not recommend Ping

I would recommend V power have had some off the V power battery's in the workshop heavy BMS

normal faults cables not thick enough burning out connectors not heavy enough

for connectors you can purchase from torberry small quantity and they will solder on

Why not Li Ping Frank, he's got a very good record, something that V power don't entirely share?
