Today I connected my 48v 5amp charger to my 48v 10ah lifepo4 battery as I've done for the past month with no problems and today it decided to blow.. Something went pow as it does and nothing at all works, no lights, no fan.. So I decided to try my other 48v 2amp charger which came with my e-bike kit and that also went pop.. Now that just has a ticking noise with the light blinking on and off with the fan but nothing working right..
I've ordered another 48v 5amp charger from ebay but before I connect it I need to know if its going to blow again.. The battery is working fine, it wasn't completely flat before I tried to charge it and still has life left in it..
I took a meter reading from the battery at both ends (the recharge end and lead to controller) and got a reading of 52.6V on both sides.. is this normal?
Does anyone have any idea whats going on and why my chargers have blown?
ps - I also open both chargers and dont see any burnt out fuses or diodes.. fuses on both chargers are ok..
