ACEPow 4s1p Hardcase battery
 

I recently purchased a ACEPow 4s1p hardcase battery. Sure, some will say that I wasted my money on an a unknown. But wouldn't it be nice to see what the unknown is capable off? I wanted the battery to have wires coming out of the casing, instead of those goofy 4mm bullets deal. It got build and send to me. It did come with the clone Deans connector and the fit and finish is just not there. It didn't come with an overkill 8awg power wires, but rather 12awg. I cracked the baby open and found 4 Gens Ace cells in there. I still haven't found anytime to actually run the battery in any of my vehicles. First it's just too hot and second family time. I did however run 1 cycle with my charger through it in my hot garage.

Garage temp 97.9F
Battery temp after first charge 98.5F. After 20A discharge rate, temp 111F.

Second charge 98.5F at 20A and 5025ma went back in.

Resistance of the cells 1.1, 1.1, 1.3, 1.1mOhm.

Shuffing 20A into the pack doesn't raise the battery temp. It's getting the amps out, raises the temps.

When I get a chance to run the battery, it will have the EC5 connector in place.

I've two of 2s 5300mah 30c ace lipos and I love them except hardcase. On a hot day race lipos puffed a little but after cooling down the cells went back to their previous form but the case didn't. I tought allways hardcase lipos are more suitable for offroad use but I'm not sure anymore.
BTW where did you find 4s Ace lipos? They are very hard to find..

Interesting how much they warmed up with just a 4C load on them, though I guess ambient temps & the constant load right down to LVC play their part. Seem like they would also be okay to remove from the hardcase & add your own shrink wrap if you so desired- its always hard to see whats happening inside a hardcase, -damaged cells or puffing etc.

Neil, it's the discharging that gets them hot.(insert LincPimp comment here). Charging them at 4C didn't increase the cells temps.

I ment discharging- 4C load = 5000mah cells being discharged at 20amps :wink:

have you had a chance to run this battery yet? i am thinking about getting one.

Ah yes, I did get to run the battery and it performs well. I charge it at 20A with no problems.

Good review I just purchased 2 of these in 2s off hobbypartz.com

I am also looking at getting cheaper li-pos as well. HobbyKing just takes to long to get and the shipping price...ugh! These may be a good alternative to the Zippys and such.

I have a n onroad project in the pipeline that needs to run 2 4s batts together so for $ 80- a set...not to bad at all

Also on their site are Blue Li-po...any one have any ideas if thgey are good?

I'll add a review of the 2s packs I got once arrived.

Thanks...just read you review. You seem to like these packs and for the price how can you go wrong.

I am tired of waiting 3+ weeks for the Zippys and these seem to be a great alternative

Any other place to get these except Hobbypartz? Worldwide shipping needed.

5300 6S 30C

Hobbypartz has never had the battery's I Want in stock. So I started buying "These" on ebay work great, US shipper and unlike the Turnegy battery's they fit great in my T3R
I run stock 17.5 so 30c is plenty.

I should have a decent review on these after tonight. Haven't raced all last week due to food poisoning, but tonight it's on like donkey kong.
