I'm excited to try out the new strategy: 1) Prolong charge & balance the pack 2) Quick discharge the 28 modules to 6V, making note of discharge...
Heehee. I've spent more on tools than modules. (and it's been almost 3 years) 1 of the modules in block 5 is bad. I could get back on the road...
Prolong's documentation for the light bulb discharger says 200W down to 140V (5V per module, less than I'll be taking them for capacity testing)....
Yessir. I have 14 AWG with a 0.02V drop from the reading on the charger. It's actually higher than the voltage at the terminals.
Jeez. The Tenergy T180 only discharges at 2A. So I guess I get to buy another thing! [MEDIA] A 250W 35A discharger that makes pretty charts....
Ok so from what I can tell, peak delta detection doesn't work with prius modules, so I'm playing it safe... First, manual cycling! Laborious, but...
Ok so first of all, every spare module has electrolyte crust on the negative post. Hoping I can clean those up. (You can see the left most module...
Went to storage today to pick up my spare modules. 13 total modules. 2 broken modules (missing post & doa cracked from ebay where the seller...
Updated plan: I just purchased a Tenergy T180 100W hobby charger and 25ft of 16 gauge copper wire. While prolong does work for balancing, I want...
I'm still struggling to understand why the car would allow this to happen. If the whole pack is toast now that's super depressing.
Hey Folks, I'm trying to figure out if my car toasted the good modules by bringing them to >9v. I didn't think it was possible, and it made a...
First: Ok, so far so good. I'll just swap block 5.
Second: Wait what?
Third: Hmm..
Fourth: Oh. Oh this is bad and scary.
Ideal outcome after using a grid discharger + balance 3 times would be a voltage difference of 0.2 or less. Is that possible, given the factory...
Hi folks, I identified 2 failing blocks and 3 weak blocks in my new used car's traction battery. Not technically a Prius, a 2012 Lexus CT200h...
