Objective Battery Test Titan LION vs. Kypom LIPO vs. HV LIPO - Valken Others

Got these in a bundle I picked up recently. Never tested the iPower brand before, will be interesting to see how it does even though these were used for an unknown amount of time.

iPower Airsoft Lipo Pack 2s 1100mAh 20C (butterfly)
Capacity - 846mAh, 76.86%
IR - 78.23mΩ, 12C, 13.1A
I'm not sure if my individual example was of below average quality, but this is not good. Worse performance than a Titanpower lol

iPower Airsoft Lipo Pack 2s2p 2200mAh 20C (butterfly)
Capacity - 1562mAh, 70.98%
IR - 26.3mΩ, 13C, 28.6A
Comparable to the Kypom 2s 2200mAh 25C, not bad. Aside from below average claimed-actual capacity%, it is a solid pack.

Do note that the 2200mAh version is a 2s2p configuration so these should be similar readings in terms of calculated C and the IR should scale accordingly. It does not.

Sorry for the late updates, but initial testing on the August 2022 batch of Guges batteries is complete. I am currently running charge cycling trials but I wanted to get this data out there when I could.


Batteries arrived safe, they are marked only with these stickers. This is really all the information I need


All of them came with miniTam connectors, some of them have foam spacers on them? They will be changed to clone Deans per usual


Connector change complete


These were sent all around 50% charged rather than the industry standard 30%

As of right now, all I have are IR readings taken after charging the battery to 100% for the first time. I assume these lipos are brand new, they certainly look it.

GUGES1 5517178P 3s 1300mAh 20C
0.20 FoM, 10C, 13.0A
111.7mΩ total pack IR
C1: 45.43mΩ (bad cell?)
C2: 29.96mΩ
C3: 28.89mΩ

GUGES2 7520100P 2s 1300mAh 20C
0.27 FoM, 12C, 15.0A
78.8mΩ total pack IR
C1: 34.04mΩ
C2: 34.58mΩ

GUGES3 6018163P 2s 1500mAh 20C
0.37 FoM, 14C, 20.3A
49.8mΩ total pack IR
C1: 20.80mΩ
C2: 21.74mΩ

GUGES7 9020120P 3s 2000mAh 20C
0.26 FoM, 11C, 22.7A
74.6mΩ total pack IR
C1: 22.78mΩ
C2: 22.14mΩ
C3: 23.24mΩ

GUGES10 753496P 2s 2200mAh 20C
0.38 FoM, 14C, 30.0A
33.8mΩ total pack IR
C1: 13.58mΩ
C2: 14.59mΩ

Initial impressions show average cell matching, with the GUGES1 lipo having a very out of balance cell that will hurt performance. This is a smaller sample size but the actual C ratings are a little lower than the Kypom batteries...which is actually a good thing (?) since the Kypoms are rated for 25C instead of 20C.

As mentioned before, charge/discharge trials are still being done to get at least 2 data points per cycle for each battery. Sorry for the wait

So, I confronted the new factory about the embellishments of their C rating and they came back with this:

"Regarding the continuous discharging C rate of the airsoft batteries, all the customers just require 10C~15C, but most of them will label it 20C or 25C, if you need the real C rate to be 20C, the MOQ for each item is 2000pcs, more over, the battery materials and manufacturing processes need to be optimized, so the cost will be up over 20%, do you think is it necessary to reach 20C? Actually our current quality can meet the airsoft gun's requirments.

We have been providing to many famous airsoft brands all over the world for many years and receive the good feedeback from them. Such as Zero one airsoft, Colombi Sports, Evolution International S.r.l. and so on. I think our batteries also can meet your requirements.

I am looking forward to hearing from your feedback soon.

Wish you a nice day!"

I am looking for packs that far exceeds AEG requirements. Most of the packs that are listed do that to a minimal degree. But I want better for people so if they "mod" the gun the pack can handle the power needs.

Rather disappointing that they lie or exaggerate to make sales...just like Airsoft Resellers.

It also confirms my suspicion that Airsoft LIPO are 2X rated in their capability for I see a lot of 20/30 C ratings, but under "continuous" use...they seem much slower than what they should be.

Apologies for taking my time with getting these results up, but here's an updated post with some extended testing. Between 10-12 cycles on each battery were done, capacity going in (at 1C) and out (at 2C) has been recorded. IR was recorded after the intial charge to 100%, and all tests were done in a climate controlled room at 65°F with enough time between tests for equipment and batteries to cool down. SD Σ ΔV (self-discharge sum of change in voltage) is the total voltage drop from all cells, measured after 10 days with the batteries fully charged and left in storage.

GUGES1 5517178P 3s 1300mAh 20C
Capacity - 1181mAh, 90.85%
IR - 111.7mΩ, 10C, 13.0A
SD Σ ΔV - 0.04v, 0.95%
Cell 1 was severely mismatched in this battery which likely led to reduced performance especially with constant discharge. A well-matched battery would drop IR to around 90mΩ and raise constant amp rating to 14A or maybe more. Above-average capacity (although still over-rated) for its class.
Verdict: Better QC would mean better performing battery

GUGES2 7520100P 2s 1300mAh 20C
Capacity - 1244mAh, 95.69%
IR - 78.8mΩ, 12C, 15.0A
SD Σ ΔV - 0.01v 0.24%
Capacity is right there but the performance is lacking. Very low self-discharge, though. I thought this would be a 2s version of GUGES1 above but for whatever reason the individual cell IR went up from ~30mΩ to ~34mΩ.
Verdict: Better capacity estimate but mediocre performance

GUGES3 6018163P 2s 1500mAh 20C
Capacity - 1266mAh, 84.40%
IR - 49.8mΩ, 14C, 20.3A
SD Σ ΔV - 0.07v, 1.68%
This one is actually not too bad, even though they severely overestimated capacity by over 18%. Self discharge was high compared to others in this batch, but the rest of the specs were great.
Verdict: Very good battery if you treat it as a 1300mAh model.

GUGES7 9020120P 3s 2000mAh 20C
Capacity - 1956mAh, 97.8%
IR - 74.6mΩ, 11C, 22.7A
SD Σ ΔV - 0.06v, 1.43%
Medium C rating but high capacity means it can dump 20A continuous no problem. The triple butterfly configuration is unusual to me, thicker than a combined stick pack and I guess would fit best in a Crane+buffer tube combo?
Verdict: Dimensionally unwieldy but if it fits it's alright

GUGES10 753496P 2s 2200mAh 20C
Capacity - 2239mAh, 101.77%
IR - 33.8mΩ, 14C, 30.0A
SD Σ ΔV - 0.04v, 0.96%
The winner of this bunch, a rare example of properly stated capacity with not too far off discharge ratings. The brick style bufferfly package unfortunately limits this one to PDW style stocks or PEQ battery boxes but the results of testing shows
Verdict: Solid battery for PDW stock/PEQ box AEGs

The original Kypom test also had a brick type battery win the 'closest specs' award of the group, I wonder if this will turn into a trend or just a coincidence. I go know that minimizing the distance away from the discharge leads is better in terms of reducing localized chemical reactions but I think 2C is low enough where this isn't really a problem.

This right here is the important part, and tells the entire story.

The experimentation we're doing is a small step in the right direction, knowing true specs will help the customer make informed decisions. I use data from e-cig forums when choosing li-ion cells for WMLs and it is extremely helpful, unfortunately I don't have as good equipment as they do. Being able to graph voltage vs time during discharge will allow quick visual comparison between batteries.

Out of all of the batteries I've tested the overall average 'actual' C rating is 63% of advertised. Those BlueMax li-ion batteries were the bottom two spots, 21.9-25.0% advertised with some of the Kypoms and funnily enough Turnigy's high end Graphene/Bolt LiHV (granted they are rated for a hilariously high 65-75C) from 28.2-37.1%. On the top end for airsoft-size batteries we have some Turnigy Nanotechs and some Kypoms in the >70% range.

Do note that Titanpower li-ions are not part of this percentile list since they do not have C ratings. To refresh everyone's memory I tested the 2600mAh and 3000mAh 2s models and they both came out to 9C...if they were rated by TP at 20C that would mean 45%, 15C would mean 60%, and a market-tailing 10C would still mean 90% advertised continuous discharge.
